I Description TWA 6

Process description in general

The Berkefeld drinking water purifier serves for provision of hygienically perfect, crystal-clear drinking water.

Every normally polluted and germ-contaminated surface or well water can be treated. The unit is not suitable for desalination of brackish or sea water.

Berkefeld drinking water purifiers operate acc. to the precoat filtration process. The raw water from rivers, lakes or wells is pumped into 4 pre-treatment tanks (8

m³ each) by means of a motor pump or electr. pump. In the single raw water tank the chemicals acc. to the Berkefeld EMERGENCY EXERCISE or ACTION SDP (standard dosing p lan) are added. The addition is effected in four steps with corresponding retention time. The water pre-treated this way is supplied to the precoat pump via the surface suction device and via the raw water collector.

In the beginning of the filtering process a certain quantity of filter material (Berkesil KE) is fed to the precoat filter by the precoat pump. By the following pre-treated raw water stream the filter material is precoated to the special Berkefeld filter candles located in the precoat filter, and there it forms the filtering layer. Flow direction in the precoat filter is upwards (see attachment 6).

After the filtration the required chlorine value in the pure water is adjusted by means of a chlorine dosator being connected in subsequent position. The chlorinated pure water is supplied to the pure water tank, and after a retention time it is supplied as drinking water to tanks or distributors by a pure water pump. By the secondary chlorination a re-infection is prevented.

With increasing pollution of the filter layer the filter head loss increases. If a filter head loss of about 3 bar is reached, the filter process is interrupted and the plant is backwashed. The flow direction in the precoat filter is now downwards. After backwash, new filter material is precoated and the filter process starts again.

The pure water reservoir facilitates short-term output peaks of about twice the capacity of the plant.

Since drinking water treatment is of utmost importance it is advisable to follow these instructions exactly and to practise all processes described in practice operation with starting and stopping the operation repeatedly.

A reliable operation can only be expected if the manual operation of the plant has been thoroughly trained on exercises and the operating staff is well acquainted with the functioning of the plant.

The exercises must be repeated every three months since an absolute reliability in operating such appliances is only guaranteed by constant repetition.

Attention

IV 1. Colour of hoses and pumps

All hoses and pumps are coloured.

All red hoses and pumps are raw water conducting plant components and may only be coupled with this colour marking.

All white hoses and pumps are pure water conducting plant parts and may only be coupled with this colour marking.

All black hoses are sludge water conducting plant parts can be coupled with red hoses for extension if required.

Red and white plant parts must not be coupled. The circulation hose is the only hose which is coloured red-

white because this conducts pure water and pretreated raw water.

IV 1.1. Installation, pumps, hoses, raw water tank

Open supporting ring (see annex 1) in such a way that the supporting ring hinges show to the bottom. Put 8 supports into the supporting ring and protect with the chains. Bring the supporting ring as near as possible to the discharge point.

Take raw water tank from the packing (packing see annex 3), unfold and suspend into the supporting ring in such a way, that the outflow hose shows to a discharge possibility (pit, at running waters below the water discharge point etc.).

Suspend discharge hose into the supporting ring. Install the other three raw water tanks in the same way and place as near as possible to the first.

Assemble the suction sets (see Attachment 2) correspondingly and couple them to the raw water tanks from inside. Suspend suction sets with the end support into the supporting ring.

Attention

Install the raw water pump as close to the intake place as possible. Connect one or two raw water suction hoses with strainer, protective basket and plastic float with chain on suction side. Secure the suction valve and hoses with an arrester cable.

Hang the raw water inflow pipe into the first raw water tank and connect it to the raw water pump with a corresponding number of raw water pressure hoses. The raw water inflow pipe is alternately hung into all raw water tanks which are then being filled.

Now the four raw water tanks have to be coupled to the raw water collector with additional raw water suction hoses. It has to be checked that all four ball valves of the raw water collector are closed.

IV 1.2 Operation/pretreatment unit

The raw water pump can be started acc. to the operating instructions for filling of the first raw water tank (see VII).

While the first tank is being filled, one prepares the treatment chemicals (chlorine, ferric chloride, activated carbon, lime) acc. to the respective standard dosing plan in the 17 l buckets filled with raw water. Take care that the chemicals are never added to the raw water tanks in undissolved condition. They should always be dissolved and stirred in a 17 l bucket filled with pure water or, if not otherwise possible, with raw water.

First fill in the water (approx. 10 l), then add the chemicals.

If the water level in the first tank has reached the knee at the raw water inflow pipe, one adds the first chemical (chlorine). One proceeds with the other chemicals (ferric chloride, activated carbon, lime) acc. to the standard dosing plan. Each time adding chemicals one has to stir vigorously with the paddle so that the chemicals are well distributed. (If available, the stirring can also be carried out with an air pipe.)

If the raw water tank is filled, one throttles the raw water pump and hangs the raw water inflow pipe into the next raw water tank. Here one proceeds just as with the first raw water tank. The same applies to the third and fourth raw water tank.

After each filtration of a raw water tank a sludge layer remains. The new filling can then be carried out as described in point IV 1.2 (use of the contact sludge). After about 5 - 10 new fillings the sludge is drained off the tank.

IV 1.3 Precoat filter

The precoat pump has to be connected with the four-way suction valve. A raw water suction hose has to be connected from the raw water collector to the four-way suction valve (C-Storz).

The precoat hose which is 2 m long and which is equipped with one Storz coupling D only has to be connected to the four-way suction valve. On the other side of the four-way suction valve the circulation hose (red-white, length 5 or 10 m) has to be connected with the circulation outlet (three-way tap) of the precoat filter.

On delivery side, a 5 m (or 2 x 5 m) raw water pressure hose has to be connected to the precoat pump to the raw water inflow of the precoat filter. The raw water inflow is always at the flow rate meter of the precoat filter.

The distances should be as short as possible (5 m circulation hose and 5 m raw water pressure hose). The precoat filter should be installed as horizontally as possible so that a proper deaeration can be effected.

The sludge hose (only equipped with one Storz-C coupling) is coupled to the StorzC outlet of the precoat filter. An extension can be effected by means of red suction hoses.

The pure water pressure hose is coupled to the pure water outlet (three-way tap) of the precoat filter.

Take care that the pure water hoses are not thrown into the dirt as this is the drinking water side.

At the end of the pure water pressure hose the chlorine dosing is connected and supplied to the covered 8 m³ pure water tank with a further pure water pressure hose via the pure water inflow pipe.

The pure water inflow pipe to the pure water tank is not hung into the tank but attached to the outside of the pure water tank so that the first pure water can be discharged (rinsing of the pure water pipes - about 30 sec). Installation of the chlorine dosator only after the pure water side has been rinsed.

IV 1.3.1 Pure water tank and pure water distributor

The pure water tank has to be installed just as the raw water tanks (see point IV 1.1; packing see Attachment 3). After hanging-in of the tank into the supporting ring, the support for the cover has to set into the tank, braced by a “spider” with the

Attention

supporting ring and the cover has to be laid on the bracing (see annex 1). Brace the cover with the cords at the supports of the supporting ring.

Pay attention to utmost cleanliness at the pure water tank.

Then on suction side the pure water pump is coupled with a pure water suction hose and a gate valve to the pure water tank (Storz C). On delivery side of the pure water pump, a corresponding pure water pressure hose is connected to which either a pure water distributor, a tapping pistol or the socket for the tank filling (truck) can be connected.

IV 1.3.2 Operation of the precoat filter

The raw water pretreated in the raw water tank can now be supplied to the precoat pump by opening the first ball valve at the raw water collector. Open main ball valve and precoat ball valve of the four-way valve, deaerate the precoat hose and fill both precoat buckets with approx. 10 l of water. This is also the easiest way to deaerate the pump. Then close both ball valves.

Then add the precoat material to both buckets (2 kg Berkesil KE, 1 kg per bucket). Another bucket with pretreated water is required for washing down the mixed precoat material. The precoat material has to be well stirred and wetted with a wooden stirrer.

At the beginning of the precoat process the slide valve being placed before the flow rate meter of the precoat filter has to be opened a little (2 - 2 ½ rotations) so that the precoat process can be carried out with a capacity of approx. 4 - 5 m³/h.

The deaerators of the precoat filter are opened, the sludge discharge ball tap is closed and the 3-way-tap is in position „filtration“. The precoat pump is started, the ball tap of the 4-way device at the precoat hose is opened and the precoating mass is sucked. If this process is finished, the ball tap of the 4-way suction device at the precoat hose is closed and the main ball tap of the 4-way device is opened for raw water feed.

The circuit ball tap of the 4-way device is always open. The pump construction allows that the precoating process can be carried out with low motor speed (fuel saving). As soon as water flows out through the deaerators of the precoat filter, they have to be closed. If the water flows through the pure water pipe at the precoat filter after a short time, the 3-way tap has to be turned to position „circuit“.

Attention

The deaerators have to be opened from time to time, so that entered air can escape. After approx. 5-7 min. circuit operation the 3-way tap is brought to position „filtration“ again.

The first water (approx. 30 sec.) should be used for rinsing of the pure water pipes. Only hereafter the pure water inflow pipe is put in the pure water tank. The full capacity of 6 m³/h is adjusted with the slide valve preceding the flow rate meter of the precoat filter. The pump pressure before the flow rate meter should be adjusted to 1 bar above filter resistance with the adjustment of the pump speed.

The minimum capacity shall not fall below 1000 l/h. The filter loss of head is readable at the pressure manometers of the precoat filter. The filter loss increases with increasing pollution. The adjusted capacity reduces, so that readjustment has to be carried out at the slide valve. If a filter loss of head of approx. 3 bar is reached at a capacity of approx. 2 m³/h and at full pump capacity, the filtration process has to be interrupted, as otherwise the plant operates uneconomically.

IV 1.3.3. Backwashing of the filter plant

During backwashing, the precoat filter is backwashed shock-wise in reverse direction, i.e. downwards. By shocking in batches (see annex 4) the solid filter layer is separated from the cartridges and flushed out through the sludge outflow hose.

The precoat filter must be backwashed with pure water.

IV 1.3.4. Bachwashing process of the precoat filter

Turn the 3-way tap of the precoat filter to position „circuit“. Close slide valve preceding the flow rate meter of the precoat filter. Switch-off precoat pump. Close main ball valve of the 4-way fitting. Open ball valve of the sludge outflow hose at the precoat filter. Open de-aeration taps of the precoat filter. Uncouple circulation hose at the circulation outlet of the precoat filter and wait until the precoat filter is emptied. Then connect the circulation hose again.

Close de-aeration taps and ball valve of the sludge outflow hose. Couple pure water pump with the pure water pressure hose (which is coupled with the pure water outlet of the precoat filter). Set 3-way valve of the precoat filter to position "Filtration" and start pure water pump. The pump has to be operated with full capacity. If the slide

Attention

valve and ball valve are closed, the pressure manometer on precoat filter side shows approx. 3 - 4 bar. The ball valve at the sludge outflow hose is opened suddenly and remains open for approx. 5 sec., then close slowly. This process must be repeated 6 times. The rinsing water flowing off the sludge outflow hose must then be clear. The sludge discharge hose must be held on to during the backwashing process or it has to be tied-up.

Switch-off pure water pump, let ball valve of the sludge outflow hose open, open deaeration valves and uncouple circulation hose at the circulation outlet and hold until precoat filter is empty.

The precoat filter is backwashed and can be started again as described under item IV 1.3.2.

Complete backwashing should not exceed 4 - 6 min.

IV 1.4.1. Purpose of the unit

The unit is used for dosing of water treatment chemicals in mobile drinking water purifiers. Installation can be carried out preceding or after a Berkefeld precoat filter plant by coupling the unit with the connections between 2 hoses. Dosing is carried out continuously into the treated pure water.

IV 1.4.2. Operation method

The dosator operates according to the back pressure displacement process, i.e. a firmly installed jam screen is installed between two connections in the main water flow, by which different pressure ratios arise in the two by-pass connections (∆ p).

∆ p

_____é ___________ê __

 P 1 P 2 ____________ ____________

By this the required quantity of water is supplied to the displacement tank via the motive water pipe with flow meter and adjusting valve. The same quantity of chemical solution is displaced and pressed into the main water flow. The adjustment of the chemical quantity to be added is carried out by an adjusting valve at the flow rate meter. The chemical solution is in a bag, which is housed in the displacement tank and which fills it out completely.

Annex 5 shows the dosing unit. It consists of the following parts: 01 Dosing tank (displacement tank)

02 Displacement bag 03 Filling and dosing connection 04 Main connections (retarding disc pipe) 05 Flow meter with adjusting valve 06 De-aerator 07 Drain

including the required connection pipes.

IV 1.4.3. Chemical addition in proportion to the water supply

The quantity of the chlorine added is determined by the corresponding responsible man in each single case. If no instruction has been given, we recommend to adjust chlorination of the water having a chlorine excess of

0.5 - 1 mg Cl2/l.

The following mentioned common chlorinous chemicals are used:

1. Chlorine bleaching solution chlorine contents approx. 12 % (sodium hypochlorite) (take care on temperature, gas evolution)

2. Chloramin chlorine contents approx. 28 %

3. HTH-chlorine (C8 powder) chlorine contents approx. 60 % - 65 % (calcium hypochlorite)

If a chlorine addition of 1 mg/l is demanded and an operation of the drinking water purifier with a capacity of 6 m³/h, the chlorine quantity to be added per hour would be 6 g Cl2/h. The flow rate meter has a measuring range of 0.5 - 5.4 l/h.

The dilution ratio of the chemical solution has been chosen in such a way that a chlorine quantity of 1 mg/l is added, if a flow rate of 1 l/h is adjusted at the control valve. The ratio between adjusted flow rate and dosing quantity remains the same at each adjustment.

For example: demanded chlorine addition of

0.5 mg Cl2/l = 0.5 l/h at adjusting valve

2.5 mg Cl2/l = 2.5 l/h at adjusting valve

If the drinking water purifier is operated with a lower capacity, the dosing capacity reduces in the same ratio (∆p).

IV 1.4.4. Preparation of the chemical solution

Wear protection clothes!

When preparing the solution, 9 l pure water and the chlorine media (corresponding to the concentration) in the following mentioned quantities have to be stirred well.

Chlorine bleaching solution 12 % 450 g Chloramin 28 % 190 g HTH-chlorine 60 % 90 g

After removal of the screwing, the prepared solution is filled (funnel) into the chlorine solution bag. The tank deaerator must be opened.

Before refilling the empty dosator, the motive water has to be discharged through the tank drain.

Before coupling the dosator into the pure water, the filter plant is switched again to circuit.

IV 1.4.5 Commissioning

During commissioning of the dosator, the following points have to be carried out exacty:

1. Close chlorine solution gate valve or separate quick-coupling

respectively

2. Close tank drain

3. Open adjusting valve completely

4. Open tank de-aeration until motive water flows out

5. Close tank de-aerator

6. Open chlorine solution gate valve or connect quick-coupling respectively and

wait until chlorine solution flows from the chlorine solution bag through the transparent overflow pipe

7. Adjust control valve to demanded value

Attention

8. Control function of the dosing unit at the control valve and overflow

pipe If the outflow for filling of a tanker has been elevated, the dosing quantity has to be

changed. Re-adjustment at control valve is absolutely necessary. If no pure water is given and the filter plant is switched to circuit, the control valve

and gate valve have to be closed or the quick-coupling has to be separated respectively. The dosator is switched off.

The dosator has to be uncoupled during backwash of the precoat filter.

IV 1.4.6. Shut-down, storage

After shut-down the plant has to be discharged thoroughly. Open all valves, so that the water can flow out from the displacement tank.

Especially the flow meter has to be protected against frost and has to be

stored in the box for accessories (blow through at opened adjusting valve).

Then unscrew the filling socket and pour out the residual chemical solution.

It is not allowed to take the full chemical bag from the tank, as it would crack from its holding.

Attention

IV 1.4.7. L E A F L E T

“Chlorine Definitions“

„Effective chlorine“ (total chlorine)

The sum of the elementary chlorine (free effective chlorine), available in the water at the point of time of analysis and its sterilizing acting compounds (bound effective chlorine) is called „effective chlorine“ (total chlorine).

„Free effective chlorine“

Chlorine, which is available in a water in form of dissolved elementary chlorine (free chlorine), hypochlorous acid or hypochlorid ions, is called as „free effective chlorine“.

„Bound effective chlorine“

Chlorine, which is available in a water in form of oxidizing acting chlorine substitution compounds (anorganic and organic chloramines) is called as „bound effective chlorine“.

Calculation as follows:

total chlorine

-free effective chlorine

= bound effective chlorine

=====================

IV 1.5. Controls during operation

All units operated with fuel must be checked at regular intervals on fuel and oil level during operation, so that a perfect operation is guaranteed. If the precoat pump would fail due to a leakage of fuel, the complete backwashing and precoating process would have to be repeated.

The same situation would occur with the electrical pumps. The current generators have to be checked continuously.

The quantity flow rate meter has to be controlled continuously during operation of the precoat filter. Should - for any reason - the precoat filter suck air or should the precoat pump fail, one would recognize this at the float of the flow rate meter and one could switch the 3-way tap to „circuit“, so that the pure water cannot be polluted.

The flow rate meter of the chlorine dosator also has to be controlled continuously, so that no excess or less dosing can occur.

The motor pumps and the electrical pumps must in no case operate in dry condition. This would cause a defect at the axial face seal or stuffing box.

IV 1.6. Dismounting of unit and storage

Thoroughly drain the plant after backwashing, with special care the flow meters at the filter tank and at the dosator (frost!).

Let all slide valves open, so that the air has free entry into the inside of the tanks. Connections provided with blind couplings to be closed only during the drive, open again in the depot.

The pumps have to be thoroughly drained before packing. Open the tap or screw at the bottom of the casing and incline the pump correspondingly (frost!).

Before packing, all plant parts have to be cleansed. If a thorough cleaning cannot be carried out at site, it has to be repeated in the depot or at any suitable place.

Before packing the raw water and pure water tanks have to be hung up at the small rings. the raw water tanks can be flushed with pure water, then dry and folded acc. to the attached plan (Attachment 3).

The plant is resistant to frost, provided that all plant parts have been thoroughly drained.

The foldable tanks are made of rot-proof, artificial material coated textile. The hose material is rot-proof as well. Despite this, hoses and tanks should be packed only after air drying. All plant parts have to be checked on completeness and readiness for use after each use.

Attention

IV 1.7. I M P O R T A N T N O T E S

If the first pre-treatment tank is pumped-off, one has to change-over to the second one in time. This is carried out by opening the ball valve at the raw water collector of tank 2 and only after that the ball valve of tank 1 is closed. The plant can be operated continuously.

It is not allowed to interrupt the started filtration, as the filter layer would fall from the filter cartridges if the water flow is interrupted. If, however, during or shortly after the commissioning the water flow is interrupted due to any reason, the unit can be started again (circuit approx. 5 - 7 min.)

The filter material fallen from the cartridges embedds by new start. If the plant had already been switched to filtration, one has to operate again in circuit during restart. But if the plant had been in operation for more than 1 hour, backwashing of the filter material has to be carried out as well as new precoating.

The operation time of the plant strongly depends on the quality of the raw water in the pretreatment tanks. In case of poor waters or at a very bad flocculation, the plant can show already after 1 hour a differential pressure of 3 bar and has to be backwashed. If the pretreatment is very good, running times of 5 - 7 hours and more can be reached at full capacity.

Operation interruptions:

If no pure water discharge is required for a short period, i.e. for 30 min., the plant capacity can be lowered by throttling the motor pump to approx. 1 m³/h. Then one switches to circuit, by which a water loss is avoided and the filter is not polluted. If water shall be given again, one only has to switch the 3-way valve from „circuit“ to „filtration“.

The filter material Berkesil KE has to be prepared already during operation for the next precoating. The precoating material only has to be stirred then and can immediately be used for further precoating after backwashing of the precoat filter.

Take care that during operation of motor pumps, the fuel tanks are refilled in time. Careful refilling of the motor pumps with fuel is absolutely required. The same applies for operation with electric pumps for the current generators.

VII Operating instructions and spare parts lists of aggregates

General operating instructions for Berkefeld pumps

Filled with water/surface water, this portable multi-purpose pump is self-priming and determined for lifting of contaminated water and sludge water. Due to its size and its weight it is especially intended as transportable multi-purpose pump, but it can also be used as stationary pump for continuous operation. It must not be flooded by the material to be conveyed and not be used in potentially explosive areas. It has to be used so that life and material do not become endangered in case of malfunction.

Combustion-engined pumps only to be used in the open air or in well-aerated rooms with tight exhaust pipe into the open air (exhaust gas hose) - danger of poisoning!

In spite of the simple the use and installation of the pump we recommend to observe these operating instructions. This will avoid damage, and the pump will be ready for operation at any time and will have a long service life.

Please give these operating instructions to the pump operator. We are, of course, prepared to send you another copy free of charge.

The pump may only be operated by trained expert personnel. We particularly point to keeping to the relevant rules and regulations.

Commissioning

Install the pump as near to the suction point as possible. Fill the pump casing with the liquid to be pumped through suction or pressure manifold. Connect suction pipe and delivery pipe.

Never operate without strainer!

Operation without strainer or protective sieve inevitably leads to destruction of the pump due to penetration of big solids.

Start the motor according to the operating instructions. Should these instructions not be ready at hand, the following hints will help you.

The suction process is effected automatically. Depending on the suction head and length of the suction pipe, the lifting starts after 10 to 300 seconds. The suction head is max. 7 m WC. If possible, the suction length should not exceed 3 x 3 m.

Important

Four-stroke fuel motor

Pump with four-stroke motor not to be installed with an inclination of more than 15°. Otherwise a lack of lubrication may occur. Check oil level.

Starting

With cold motor, adjust lever to CHOKE; with warm motor to RUN up to ¼ direction to CHOKE. Gas lever to FAST. Slowly pull the hand lever of the reversing starter until gearing, then pull hard and slowly return the hand lever again. Do not pull out the starter cable up to limit stop! After start, slowly turn the lever from CHOKE to RUN or open the CHOKE flap, respectively.

Switching off

Bring motor to idle-running speed and set lever/rotary switch to OFF. Advice from practical experience: Adjust the lever/rotary switch to RUN/ON again after switching off; then the ignition is not interrupted inadvertently during the next start.

Diesel motor

Check oil level.

Starting

Turn decompression lever until marking (pin) is on 12 o’clock position. Turn speed control lever to full throttle and turn the motor with crank first slowly and then faster and faster.

Switching off

Fully reset speed control lever.

Maintenance

In case of strongly polluted liquids and danger of frost, drain the pump after use. Should the pump get stucked in case of frost in spite of draining, the impeller is released again by some warm water.

Never thaw with open flame! For draining, remove the plug at the bottom of the casing and then tilt the pump forward

so that the water can drain off completely. The pump has no lubricating points. Carry out maintenance of the motor according to the maintenance instructions. Regularly

carry out oil change with the four-stroke fuel motors and the diesel motors.

Repair instructions

1. Dismantling

1.1 Drain the pump by opening the screw plug (13).

1.2 Release the screws for fastening the motor on the sledge and detach the motor together with the pump from the sledge.

1.3 Release the screws for connection of the pump casing (11) with the pump cover (1). Detach the pump casing (11) and then the flow director (8) from the pump cover (1).

1.4 For exchange of the shaft sealing, unscrew the impeller (6) from the motor shaft (right-hand thread). For that, stop the crank of the fuel motor; if necessary dismount the reversing starter. With the diesel motor, remove the lateral grid and keep hold of the flywheel. Pull off sliding ring (5) from the impeller and remove counter-ring (4) and O-ring (3) from the cover (1). Replace if necessary.

2. The assembly is carried out in reverse order.

The following has to be observed:

2.1 When installing the counter-ring (4), do not forget the O-ring (3) to be installed underneath.

2.2 After having pinned up the flow director (8) on the grooved pin (2) of the pump cover, adjust the ventilation duct between edge of the flow director (8) and impeller (6) to approx. 0.2 mm (put a paper strip in between). For adjusting the ventilation duct and for putting on the pump casing (11), put motor on the fore-part so that the pump cover is in horizontal position. Put O-ring (9) on flow director (8), „stick“ the O-ring (10) with fat into the groove of the casing (11) and assemble the casing.

3. Lubrication is not required.

The total hardness of the water is composed of calcium and magnesium salts. The carbonate hardness consists of hydrogen carbonate (HCO3).

Total hardness (TH) = carbonate hardness (CH) + non-carbonate hardness (NCH). A common measuring unit in Germany is 1 mval/l = 2,8 °dH (German hardness). French and English hardness degrees are measured as well.

1 °dH = 1,79 °fH = 1,25 °eH For flocculation iron and aluminium salts are often used, e.g.: Ferric chloride

Iron sulphate Aluminium sulphate Polyaluminium chloride

These salts are compounds of the corresponding metal and of the corresponding acid, e.g.

2 Fe + 6 HCl = 2 FeCl3 + 3H2 This iron salt has the property to flocculate the dirt and suspended matter being available

in the water and to sediment them then. FeCl3 + 3 HOH = Fe(OH)3 + 3 HCl During this process hydrochloric acid develops. This acid eats away the carbonate

hardness of the water. (A strong acid expels the weaker acid from its compound.) Ca(HCO3)2 + 2HCl = CaCl2 + 2 H2CO3 During this process the pH-value of the water is reduced; this applies to all conventional

flocculants. Examples: At a low carbonate hardness of 0.5 °dH and addition of approx. 50 g/m3 iron or aluminium

chloride, the pH-value may reduce to approx. 2 - 3. At a carbonate hardness of 10 °dH and addition of approx. 100 g/m3 flocculants there is

only a reduction to a pH-value of 5 - 6. 1°dCH is used up by 20.5 mg aluminium sulphate

by 19.3 mg ferric chloride by 17.1 mg sodium aluminate

Besides the pH-value, the conductivity and the temperature, the carbonate hardness is a very important factor for the raw water analysis.

The correct assessment in the analysis helps to save chemicals.

Explanation friction losses in pipes Shall water be pumped over a longer distance, the table located in the plant can be used. If a water flow of 10 m3/h shall be pumped over a distance of 1000 m, using a pipe with an

inside diameter of 50 mm, this means a loss of 5.25 m WC per 100 m. At a distance of 1000 m this means a pressure loss of 5.25 bar. When using the next bigger pipe diameter (70 mm), the loss over 1000 m is only 1.4 bar.

With this table it is possible to calculate from the start how many m³ of water do arrive at the corresponding distance with the corresponding pressure losses.
