GENERAL

1 General

1.1Introduction

This service manual contains basic instructions and information which are to be observed upon set-up, operation and maintenance.

Therefore, it is imperative that the service manual is read by the installer as well as by the responsible specialist staff prior to installation and starting of operation. Please observe not only the general safety instructions listed in the section “Safety Instructions”, but also the special safety instructions included in the other sections.

1.2Marking of Instructions

The safety instructions contained in these operating instructions, which in case of non-observance can cause dangerous situations for persons, are specially marked with the general symbol for dange.

The safety instructions contained in these operating instructions, which in case of non-observance can cause poisoning, cauterizing, etc. for persons, are specially marked with the death’s-head symbol.

CAUTION Following this symbol are recommendations or tips which make working easier and provide for secure operation.

NOTE Following this symbol are recommendations or tips which make working easier and provide for secure operation.

Instructions that are attached directly to the equipment must be observed under all means and kept in completely readable condition.

1.3Intended Use

The equipment is intended for the conditioning of untreated water into drinking water.

The retention degree of harmful chemical substances and biological pathogens or contaminants is very high.

The quality of the produced drinking water ultimately depends on the contamination degree and salt content of the untreated water.

-Prior to the initial starting of operation, we recommend carrying out an analysis of the untreated water.

-Continuous drinking-water quality can be ensured only when the equipment is controlled regularly.

-The respective national or international drinking water regulations are to be observed.

Under consideration of these rules of conduct, water produced from this system can quite safely be classified as drinking water.

GENERAL

WTC 600 LP / MP

1.4Safety Instructionse

1.4.1Quality of the Untreated Water

Sufficient quality of the untreated water must be ensured!

Faultless drinking water is achieved only when all filters of the equipment are maintained regularly.

1.4.2Chlorination of Drinking Water

When applying post chlorination, the limit values set by national laws must be maintained. The chemicals used have a caustic and fire-promoting effect.

Dangers:

-Danger of fire in case of contact with combustible materials.

-Toxic gas develops when coming in contact with acids.

-Heat or direct sunlight decomposes the chemical: Chlorine and oxygen are released.

-Caustic effects to the eyes, skin and respiratory system result.

Safety Instructions:

-Wear acid-resistant protective equipment (goggles, gloves) and when dust is produced, breathing mask protection with a filter.

-Keep an eye wash bottle (small) readily available.

-Provide for adequate room ventilation and a washing facility.

-Store the chemicals in a cool, dry place, not below 5 °C.

-Store chemicals in a location out of the reach of children.

In Case of Accidents:

-In case of contact with the eyes, rinse immediately and thoroughly with fresh water and consult a doctor.

-Use water to extinguish; avoid impact and friction.

-If solutions are spilt, flush the area with a sufficient amount of fresh water.

1.4.3Disposal of Chemicals

It is generally recommended to admit resulting disinfection solutions, preservation solutions, etc. into a neutralizing system.

If this should not be possible, the disinfection solution, after clarification with the relevant authority (mayor’s office, district administration office, etc.) is to be neutralized and can afterwards be led into the public sewer system.

2.3.3Operating Modes

2.3.3.1Automatic Operation (Standard Operating Mode)

After switching on the main switch, the system is fully automatic controlled through the electronic control system and the float switch in the drinking water tank. The mode selector switch is in the “Auto” position.

The control system usually operates in the normal plane in the operating mode operation.

With the exception of an error acknowledgement (only in case of pre-selection Vwacknowledgement by actuating the ESC key button), no further operating by the operator is possible; this is to protect the control system against unintended / unauthorized manipulations.

NOTE By entering the respective password, the user level or the technician level for input of operating parameters, etc. is cleared (see section 3.4.3.1). The program structure is given in the appendix, Figure 21.

NOTE Operating parameters and setting values are listed on the data sheet by the manufacturer (cf. Tables 34 and 35).

2.3.3.2Manual Operation

The float switch in the drinking water tank is deactivated by the manual / automatic rotary switch ("Manual" position), so that the plant can run continuously.

CAUTION Manual operation is not standard operating mode, as the system does not switch off automatically.

OPERATION OF THE SYSTEM

3.2Mixing Chlorine, Flocculation Agent and Antiscalant

3.2.1First fill of the metering tanks

The first time they are filled, the metering tanks are filled with 30 litres of chlorine-free water. This is taking from the reverse osmosis at the drinking water sampling tap (1/12).

For the first fill of the metering tank, the system is switched to disinfection mode and set to the following flow rates:

-Drinking water: 100 l/h

-Concentrate: 600 l/h

CAUTION During the disinfection operating mode, all confirmation queries are switched off! Observe the pressure downstream of the fine filer: as soon as it is less than 2 bar pressure, immediately switch off the system. The high-pressure pump is running dry!

Use the prescribed system yield (50% or 75%) and the water analysis to determine each of the chemical quantities for a 30 litre metering solution according to Chap. 3.2 to 3.5, add to the tanks and mix well.

Switch the system to operation mode.

3.2.2 Pre-chlorination

CAUTION Only use drinking water to dilute the original chlorine product upstream of the chlorination point. This water is taken from the drinking water tap (1/4.21).

1.Take the system yield (50% or 75%) from the evaluation of the untreated water analysis.

2.Take the analysis values for iron (Fe), manganese (Mn) and ammonium (NH3 or NH4 ) in mg/l from the untreated water analysis.

OPERATION OF THE SYSTEM

3.2.3Antiscalant

The drinking water for the metering solution is taken from the sampling tap for drinking water (1/4.21).

The antiscalant metering quantity can be set with a very good approximation using the following table. The optimum quantity can only be calculated using a calculation program after a precise water analysis has been carried out. The typical metering range lies between 2 and 5 mg/l.

Where water hardnesses are higher than 28°dH, special design is necessary.

If this design is not possible, the following setting is recommended: 5 mg/l RM5000 and 50% yield, until the precise design is available.

3.2.4Metering Amounts and Mixing of the Post Chlorination

The chlorine quantity given matches a chlorine content of 0.3mg/l in the drinking water.

The following quantities of RM 852 or calcium hypochlorite are each required for 10 litres of metering solution:

-

RM 852 Sterilization Agent:

32 ml

-

Chlorinated Lime:

17 ml (= 18 g)

Example: 75 litres ready mixed metering solution (one metering tank) consists of 7.5 x 32 = 240 ml RM 852 or 7.5 x 17 = 128ml (=136 g) calcium hypochlorite and chlorine-free drinking water (cf. Chapter 3.2.3 for extraction).

The quantities must be adjusted accordingly for higher or lower chlorine contents.

Example: Chlorine content: 1.2 mg/l

-

RM 852:

4 x 32 ml = 128 ml

-

Chlorinated Lime:

4 x 17 = 68 ml

3.2.5Flocculation Agent

The exact demand in flocculents can only be determined by test. Therefore a test solution is mixed first, then the raw water is flocked and finally the dosing quantity is evaluated.

3.2.5.1Mixing of the flocking test solution

Auxiliaries:

-Measuring cup with 500-ml-scale 6.277-001.0 (within service kit)

-Desalinated water (refill water for car batteries)

-Flocculent RM 5001 6.294-716.0 resp. 6.294-703

-Measuring cup 25 ml 6.394-425.0 (within service kit)

-Dropping bottle 50 ml,PE 6.394-426.0 (within service kit)

-Plastic eating spoon.

Work Steps:

1.Give 25 ml flocculent RM 5001 into measuring cup

2.Fill up with desalinated water to 500 ml

3.Stir up thoroughly with plastic eating spoon

4.Give 50 ml of this into a clean dropping bottle, close bottle

5.Cast away the remainder.

Service Handbook 08.2004

WTC 600 LP / MP

OPERATION OF THE SYSTEM

3.2.5.2Perform flocking test

Auxiliaries:

-Transparent cup, 1 litre with marking at 0.5 litre 6.277-001.0

-Dropping bottle with test solution 6.394-426.0

-Plastic eating spoon.

Work Steps:

1.Measure pH-value of water, has to be between 6 and 9

2.Pour 0.5 Liter raw water into cup

3.Give 10 drops of flocking test solution into spoon

4.Fill flocking test solution into cup, at this stir strongly for 5 seconds

5.Leave cup: flocking has to start within 1 minute and settle significantly.

NOTE If no flockung has start repeat test and change quantity of flocking test solution (first more test solution, if not successful repeat with less test solution).

If analysis is not possible on the spot, take out 2 litres of test solution and store in refrigerator at ca. 4°C until analysis. Cooling maintains cloudiness by suspended matter.

NOTE Shake well before measurement in laboratory.

3.2.5.3Evaluate flocking test

Adjustment of dosing pump flocking means:

-Stroke: 40%

-Frequency: 70%.

The required amount of flocculation agent RM 5001 is then calculated as follows:

-For 50% yield: number of drops x 120 = ml RM 5001 per 10 litres metering solution

-For 75% yield: number of drops x 80 = ml RM 5001 per 10 litres metering solution

Calculation example:

The flocculation test gave 11 drops of flocculation test solution to 500ml up to ideal flocculation, the yield is 75%:

11 drops x 80 = 880 ml RM 5001 per 10 litres of metering solution
