SIGNIFICANCE OF

POOL AND SPA TESTING

A major family leisure pursuit is the enjoyment of Swimming Pool and Spa facilities world-wide. A basic necessity of Pool water treatment, to ensure such enjoyment, is to maintain the water in a safe and pleasant condition for the bathers.

In order to achieve such an objective, swimming pool water requires testing on daily, and sometimes hourly bases for disinfection residuals and pH. Equally important, Calcium Hardness and Alkalinity parameters should be monitored on weekly bases to ensure the pool water is maintained in a balanced condition, thus to avoid system failure because

of corrosion or scale formation.

DISINFECTION RESIDUAL AND pH CONTROL

In terms of swimming pool treatment, disinfection or sanitizing basically means to rid the pool of bather pollution, destroy bacteria, and control nuisance organisms like algae, which may occur in the pool, filtration equipment, and piping.

There are a number of techniques used, namely, chlorine, bromine and ozone dosing systems, of which chlorine is the most common.

Chlorine

Chlorine is a strong oxidizing agent that destroys mostly organic pollutants, bacteria and can combine with nitrogen containing compounds, forming chloramines. Only a part of the original quantity dosed chlorine, remains active and continues its disinfecting action.

From the free chlorine you can distinguish combined chlorine, as that part which combines with nitrogen containing compound and that is less efficient as a disinfectant. The addition of these two parts gives total chlorine. A pool manager needs to aim perfection where free equals total chlorine, and thus to maintain the combined chlorine concentration near zero. The presence of chloramines is not desired because of the distinctive ‘swimming pool’ smell caused by combined chlorines like dichloramines. Beside this unpleasant odour it does irritate the eyes and the mucous membranes.

Commercially chlorine for disinfection may be available as a gas (Cl2), a liquid like sodium hypochlorite or bleach (NaOCl) or in a solid state like calcium hypochlorite, chloro-hydantoins or chloro-cyanuric acid compounds.

These compounds, once dissolved in water do establish equilibrium

between the hypochlorous acid (HOCl) and the hypochlorite ions

(OCl-).

Although both forms are considered free chlorine, it is the hypochlorous acid that provides the strongest disinfecting and oxidising characteristic of chlorine solutions.

The amount of hypochlorous acid in chlorinated water dependends upon the pH value of the solution. Changes in pH value will effect the HOCl equilibrium in relation to the hydrogen and hypochlorite ion.

As depicted by the curve below, HOCl decreases and OCl- increases as pH increases. At a low pH, almost all the free chlorine is in the molecular form HOCl and at a pH of around 7.5, the ratio between HOCl and OCl- is 50:50. Since the ionic form OCl- is a slow acting sanitizer while the molecular HOCl is a fast acting, it is important to measure regularly the pH. As a general rule a pH of about 7.2 is recommended to maintain fast acting disinfection conditions.

Bromine

In many countries bromine sanitizing has been introduced as an alternative for chlorine, although it is a less strong sanitizer. The advantage of bromine is its stability at higher temperatures (advantageous for hot well pools), and its maintained disinfection power at higher pH. Further it does hardly react with nitrogen compounds, reducing the unpleasant odour, and eye irritation problems. The main disadvantage of bromine is the slower acting disinfecting power, making it less suitable for larger pools.

Ozone

Ozone is a very strong oxidizing agent that does destroy most difficult to oxidize organic compounds and chloramines. It thus allows the pool manager to remove very efficiently combined chlorine without refreshing

frequently large amounts of pool water. In general its application is found just before water passes through the filter units. Its sanitizing power is not pH related.

Mainly because of its strong oxidizing power the return water may contain only trace concentrations of ozone. It has to be mentioned that ozone is very unstable and there is anyway the need for low-level chlorination to ensure sanitizing throughout the whole pool.

THE WATER BALANCE AND LANGELIER INDEX (LI)

The pool water characteristics need to be maintained in a balanced condition to avoid system failure. Measuring the water balance is extremely important to predict if the water is corrosive, scaling or balanced.

A saturation index developed by Dr. Wilfred Langelier is widely used to predict the balance of swimming pool waters. It is an estimation of the solutions ability to dissolve or precipitate calcium carbonate deposits. A certain level of this precipitation (filming) is desired to insulate pipes and boilers from contact with water. When no protective filming is formed, water is considered to be corrosive. On the other hand scaling does cause failure because of incrustation problems.

In the treatment and monitoring of pool water, the pool manager must ensure that related parameters as alkalinity, hardness and pH are duly taken into consideration.

Calcium Hardness

The presents of calcium in the system is desired to ensure filming on those places where the temperature is relatively high, like in boilers and pipes transporting warm water. Scaling must be avoided because it reduces heat transfer and pump capacity. Beside the calcium carbonate deposits in the pipes, high scaling values do cause cloudy water.

It is recommended to maintain the calcium hardness value within the range from 200 to 400 ppm as calcium carbonate (CaCO3).

Alkalinity

Alkalinity is the measure of the total concentration of alkaline substances, mostly bicarbonates, dissolved in the water. The higher the alkalinity the more resistant the water is to pH change, the alkalinity buffers the water. At the same time, high alkaline water is a major contributor to scaling problems like incrustation in filtration equipment, pumps, and piping.

It is recommended to maintain the alkalinity value within the range from 80 to 125 ppm as calcium carbonate (CaCO3).

The pH of the water is an important factor since at lower pH the corrosion

rate increases. If the alkalinity values are sufficiently high it will not be difficult to control the pH. Most pools managers do prefer to keep the pH between 7.2 and 7.4, that does ensure low corrosion rates and a sufficient activity of chlorine.

Langelier Index (LI)

The Langelier Index is a powerful tool to calculate the water balance, and to predict corrosion or scaling problems. Theoretically, a LI of zero indicates perfect water condition for swimming pools. If LI>0, scaling and staining of the water is present, and if LI<0 the water is corrosive and highly irritating. A tolerance of ±0.4 is normally acceptable.

The Langelier formula is expressed as:

LI = pH + TF + HF + AF – 12.5

where:

LI = Langelier Index (also called Saturation Index) pH = pH of the water TF = temperature factor HF = hardness factor, log(Ca Hardness, ppm as CaCO3) AF = alkalinity factor, log(Alkalinity, ppm as CaCO3)

To calculate the exact Langelier Index of your water please use the WATER INDEX reference tables at the end of this chapter to find the Temperature, Hardness and Alkalinity factors.

Recommendations

For most pools, water is balanced if:

• The pH value is maintained within the recommended ranges of

pH 7.2 - 7.6

• Ideally the Alkalinity should be maintained within a range of

80 - 125 ppm

• The Calcium Hardness should be maintained within a range of

200 - 400 ppm.

To calculate your water balance three tests are required, measure the Calcium Hardness, the Alkalinity and the pH of the pool water. Find the Hardness and Alkalinity Factor in the WATER INDEX reference tables below.

The water temperature is in general controlled between 24oC (76oF) and 34oC (94oF) to ensure pleasant bather comfort. The Temperature Factor in this temperature range has minor importance; therefore an average value of 0.7 may be used

A simple calculation classifies your water in corrosive, scaling, acceptable or ideal balanced, with treatment recommendations:

Water Balance = pH + TF + HF + AF

PRECISION AND ACCURACY

Precision is how closely repeated measurements agree with each other. Precision is usually expressed as standard deviation (SD).

Accuracy is defined as the nearness of a test result to the true value. Although good precision suggests good accuracy, precise results can be

inaccurate. The figure explains these definitions. For each parameter, the precision is expressed in the related measurement

section as standard deviation at a specific concentration value of the analite. The standard deviation is obtained with a single instrument using

a representative lot of reagent.

PRINCIPLE OF OPERATION

Absorption of Light is a typical phenomenon of interaction between electromagnetic radiation and matter. When a light beam crosses a substance, some of the radiation may be absorbed by atoms, molecules or crystal lattices. If pure absorption occurs, the fraction of light absorbed depends both on the optical path length through the matter and on the physicalchemical characteristics of substance according to the Lambert-Beer Law:

-log I/Io = ελ c d

A = ε

c d

Where:

-log I/Io=Absorbance (A)

Io=intensity of incident light beam I =intensity of light beam after absorption

ελ=molar extinction coefficient at wavelength λ

c =molar concentration of the substance d =optical path through the substance

Therefore, the concentration "c" can be calculated from the absorbance of the substance as the other factors are known.

Photometric chemical analysis is based on the possibility to develop an absorbing compound from a specific chemical reaction between sample and reagents.

Given that the absorption of a compound strictly depends on the wavelength of the incident light beam, a narrow spectral bandwidth should be selected as well as a proper central wavelength to optimize measurements.

The optical system of Hanna's C 99 & C 200 Series multiparameter photometers is based on special subminiature tungsten lamps and narrow-band interference filters to guarantee both high performance and reliable results.

Four measuring channels (at four different wavelengths) allow a wide range of tests.

C 200 Series block diagram (optical layout)

A microprocessor controlled special tungsten lamp emits radiation which is first optically conditioned and beamed to the sample contained in the cuvet. The optical path is fixed by the diameter of the cuvet. Then the light is spectrally filtered to a narrow spectral bandwidth, to obtain a light beam of intensity Io or I.

The photoelectric cell collects the radiation I that is not absorbed by the sample and converts it into an electric current, producing a potential in the mV range.

The microprocessor uses this potential to convert the incoming value into the desired measuring unit and to display it on the LCD.

The measurement process is carried out in two phases: first the meter is zeroed and then the actual measurement is performed.

The cuvet has a very important role because it is an optical element and thus requires particular attention. It is important that both the measurement and the calibration (zeroing) cuvets are optically identical to provide the same measurement conditions. Whenever possible use the same cuvet for both.

It is necessary that the surface of the cuvet is clean and not scratched. This is to avoid measurement interference due to unwanted reflection and absorption of light. It is recommended not to touch the cuvet walls with hands.

Furthermore, in order to maintain the same conditions during the zeroing and the measuring phases, it is necessary to close the cuvet to prevent any contamination.

This indicates that the meter is in a ready state and zeroing can be performed.

Sampling in progress. This flashing prompt appears each time the meter is performing a measurement.

The microprocessor is adjusting the light level, indicated by a scrolling "SIP".

This indicates that the meter is in a zeroed state and measurement can be performed.

The instrument is performing an internal check-up.

The blinking "LOBAT" indicates that the battery voltage is getting low and the batteries need to be replaced.

This indicates that the batteries are dead and must be replaced.

Light over range. The cuvet is not inserted correctly and an eccess ambient light is reaching the detector. If the cuvet is properly inserted, then contact your dealer or the nearest Hanna Customer Service Center.

ERROR MESSAGES a) on zero reading:

The lamp is not working properly. Contact your dealer or the nearest Hanna Customer Service Center.

This indicates that the meter has lost its configuration. Contact your dealer or the nearest Hanna Customer Service Center.

This indicates that the zeroing procedure failed due to a low signal-to-noise ratio. In this case press ZERO again.

The instrument cannot adjust the light level. Please check that the sample does not contain any debris.

There is not enough light to perform a measurement. Please check the preparation of the zero cuvet.

b) on sample reading:

There is too much light to perform a measurement. Please check the preparation of the zero cuvet.

There is too much light for the sample measurement. Please check if the right sample cuvet is inserted.

The sample and zero cuvet are inverted.

A zero reading was not taken. Follow the instruction described in the measurement procedures for zeroing the meter.

Under range. A blinking "0.00" indicates that the sample absorbs less light than the zero reference. Check the procedure and make sure that you use the same cuvet for reference (zero) and measurement.

1) A flashing value of the maximum concentration indicates an over range condition. The concentration of the sample is beyond the programmed range: dilute the sample and rerun the test.

2) A flashing value lower than the maximum concentration indicates a low signal-to-noise ratio condition. In this case accuracy of the result is not guaranteed. Repeat the reading procedure.

TIPS FOR AN ACCURATE MEASUREMENT

The instructions listed below should be carefully followed during testing to ensure best accuracy.

• Color or suspended matter in large amounts may cause interference, therefore, these should be removed by treatment with active carbon and by prior filtration.

• For a correct filling of the cuvet: the liquid in the cuvet forms a convexity on the top; the bottom of this convexity must be at the same level of the 10 mL mark.

• Proper use of the dropper: (a) to get good reproducible results, tap the dropper on the table

for several times and wipe the outside of the dropper tip with a cloth.

(b) always keep the dropper bottle in a vertical position while

dosing the reagent.

10 mL

(a) (b)

• Proper use of the powder reagent packet: (a) use scissors to open the powder packet; (b) push the edges of the packet to form a spout; (c) pour out the content of the packet.

(c)(a) (b)

• It is important that the sample does not contain any debris. This would corrupt the reading.

• In order to avoid reagent leaking and to obtain more accurate measurements, it is recommended to close the cuvet first with the supplied HDPE plastic stopper and then with the black cap.

• Each time the cuvet is used, the cap must be tightened to the same degree.

• Whenever the cuvet is placed into the measurement cell, it must be dry outside, and completely free of fingerprints, oil or dirt. Wipe it thoroughly with HI 731318 (tissue for wiping cuvets, see chapter ACCESSORIES) or a lint-free cloth prior to insertion.

• Shaking the cuvet can generate bubbles in the sample, causing higher readings. To obtain accurate measurements, remove such bubbles by swirling or by gently tapping the vial.

• Do not let the reacted sample stand too long after reagent is added, or accuracy will be lost.

• It is possible to take multiple readings in a row, but it is recommended to take a new zero reading for each sample and to use the same cuvet for zeroing and measurement.

• After the reading it is important to discard immediately the sample, otherwise the glass might become permanently stained.

• All the reaction times reported in this manual are referred to 20°C (68°F). As a general rule of thumb, they should be doubled at 10°C (50°F) and halved at 30°C (86°F).

INTERFACE WITH PC

To connect your meter to the PC use the optional HI 920010 (available from your Hanna Dealer). Make sure that your meter is switched off and plug the connectors, one into the meter RS 232C socket, the other into the serial port of your PC.

Note: Cables other than HI 920010 may use a different configuration,

in which case, communication between the meter and the PC may not be possible.

SETTING THE BAUD RATE

The transmission speed (baud rate) of the meter and the external device must be identical. The meter is factory set to 2400.

If you wish to change this value, please contact your nearest Hanna Center.

SENDING COMMANDS FROM PC

With terminal programs such as, for example, Telix®, Windows Terminal®, it is possible to remotely control your Hanna Instruments bench meter. Use HI 920010 cable to connect the meter to the PC, start the terminal program and set the communication options as follows: 8, N, 1, no flow control.

Command Types

To send a command to the meter the scheme is:

This line makes the computer send a Data Link Escape character (/ or ?), the command expressed as a number or a 3-character sequence and a CR character.

Note: Windows Terminal® and all the other terminal programs that

support the ANSI escape sequence, represent the DLE character by the string ‘^P’ and the CR character by the string ‘^M’.

BATTERY REPLACEMENT

To prolong battery life, switch your meter off after use. However, the meter has an auto-shut off feature that will turn itself off after 10 minutes of non-use.

A blinking "LOBAT" on the display, while a measurement is in progress, indicates low voltage and the batteries should be replaced.

If the batteries are not replaced immediately, in order to prevent erroneous readings due to low voltage, "-BA-" is displayed soon afterwards. At this point the batteries must be changed.

Battery replacement must only take place in a non-hazardous area using two 9V alkaline batteries.

Remove the battery cover on the back of photometer, attach two fresh 9V batteries, while paying attention to the correct polarity, and replace the cover.

The meter will turn on automatically when a new battery is connected. You can turn it off by pressing ON/OFF.

Besides to 9V batteries, these meters can also be fed by the optional 12 to 20 VDC through voltage adapter.
