5 Pools & Spas Swimming and bathing are without doubt some of the most popular leisure activities, whether at school, in a competitive environment, for exercise or simply relaxation. The concept of "Wellness has created a new trend; wellness enthusiasts are people who have made a conscious decision to stay fit and active with the aim of achieving/maintaining good health and a general feeling of well-being and attaining harmony of body, mind and soul. In order to achieve this goal, people make wide-ranging use of swimming pools, spas, and many other similar facilities. Regardless of the motivation for swimming and similar activities, people attach great importance to clean and hygienic water both indoors and out. Water Treatment and Water Testing State-of-the-art water treatment is an essential precondition for safe and healthy bathing and swimming whether in private or public facilities. In order to satisfy health-related criteria while maintaining the value of such a facility, the golden rule for water treatment is "as much as necessary and as little as possible. It goes without saying that the main water quality parameters need to be checked on a regular basis in order to ensure an optimum water treatment programme in changing operating conditions. If testing shows that the hygiene-related parameters deviate from the target values or recommended limit values, the operator can immediately take corrective action to avoid potential risks to health before such risks are allowed to arise. And this is where the system of Lovibond water testing equipment and reagents comes into play. The Lovibond range of instruments provides operators of private and public baths with analysis systems that measure the actual condition and quality of the water with maximum precision. Moreover, the Lovibond systems succeed in reconciling the seemingly irreconcilable goals of easy handling, safe reagents offering long-term stability, high detection accuracy, and reproducibility of results. We hope you will find the information on the following pages convincing. 4 Regularly updated information: Pool & Spa Water Testing March 2011

8 Water Treatment Rapid Tests ph value The ph value of pool & spa water should generally be between the slightly acidic value of 6.5 and the slightly basic value of 7.6. Due to the use of various water treatment chemicals as well as ambient environmental effects, pool owners have to determine the ph of the water and correct the value as necessary. DIsinfeCtion Nowadays, pool owners can choose from a range of modern water treatment agents that are often used in combination. These water treatment chemicals are only effective within a limited ph range. Therefore in addition to checking the concentration of the water treatment chemicals, the owner/ operator should also monitor the ph value of pool water and adjust it if necessary. MINITESTER The MINITESTER with an interchangeable colour comparison chart is a competitively priced starter unit with one measuring chamber for the determination of either chlorine, bromine, active oxygen and the ph value. THREE-CHAMBER TESTER The THREE-CHAMBER TESTER with an interchangeable colour comparison chart is a competitively priced unit for the determination of disinfectants and the ph value. POOLTESTER The POOLTESTER allows simultaneous determination of the most popular water treatment agents and the ph value. POOLCHECK The term "balanced water" is used to describe water that is neither corrosive nor prone to scale formation. The function of the POOLCHECK is to test for these water properties. The POOLCHECK comprises all the components required for determination of free chlorine, ph value, calcium hardness, total alkalinity and, optionally, acid demand and cyanuric acid. All the above testers, determinations, ranges and refill packs are listed on the following two pages. Rapid Tests Highlights. fast accurate simple. ready to use.

12 The Methods The MINIKITS are developed for fast testing, mainly based on titrimetric methods Rapid Tests Tablet count method A specific number of tablets is added to a known volume of sample until a chemically induced colour change takes place. The number of tablets used is applied to a simple formula to calculate the test result. The measuring range may be expanded by varying the sample volume. Speed test The speed test is based on reverse titration. After adding a reagent tablet to a calibrated test tube, the water sample is added slowly until the colour of the solution changes (e.g. from red to blue). The user can then obtain the result from the liquid level. Yes/No test A Yes/No test tells the user whether a specific ingredient is present in the water and/or if its concentration is higher or lower than a defined level. Turbidity method A two-section calibrated test tube is filled with the water sample and a reagent tablet added. The reagent creates a level of turbidity that is proportional to the concentration of the parameter being measured. The inner tube, which has a black dot on its base, is lowered until the dot is obscured by the turbidity. The result is read off from the water level in the inner tube. Highlights. Easy operation.

14 Scuba and Scuba + For peace of mind, anyone owning a pool should carry out regular checks on the most important characteristics of the water in the pool (the socalled hygiene parameters). So the quality of the water can be checked and the water treatment chemicals can be dosed to meet the requirements. The Scuba is an immersible test device which uses a similar technology to that used in public pools. A sample of the water is tested using the photometric principle and the result is shown in the digital display. Compared to visual pooltester systems this eliminates the risk of wrong colour readings. The unit has a modern housing designed to meet ergonomic requirements and is, of course, fully watertight. The Scuba is supplied with specially formulated, quick-dissolving reagent tablets (identified by their white foil packaging). It also has a handy strap so that it can be hung safely in a storage area.

33 Photometry The History Several decades have passed since the appearance of the first Lovibond PC 100 photometer system. Since that time, Tintometer has become a world-famous name as the manufacturer of photometer systems sold under the brand name of Lovibond. Our range of photometer systems extends from the CheckitDirect to the SpectroDirect spectrophotometer (see general catalogue). The multi-functional PoolDirect provides the answer to all requirements relating to the analysis of water used in modern swimming pools and baths. It offers a wide variety of pre-programmed methods and is therefore suitable for the demands of modern water analysis. A modern, laboratory photometer for rapid, reliable water testing is the SpectroDirect. The latest development involves the pocked sized format photometer MD 100. Parameter Alkalinity-M (total) Aluminium Ammonia Bromine Calcium Hardness Chlorine Chlorine Dioxide Copper Hydrogen Peroxide Iodine MD 100 CheckitDirect CheckitDirect + PoolDirect PoolDirect 9 in 1 All the parameters which can be measured with Lovibond photometer systems are set out in the table. This table also explains what parameters can be measured with which photometer. Iron (Fe 2+, Fe 3+ ), soluble Langelier Water Balance MD 100 CheckitDirect PoolDirect 32 Regularly updated information: Pool & Spa Water Testing March 2011

34 Parameter Manganese Oxygen, active MD 100 CheckitDirect CheckitDirect + PoolDirect Ozone ph value PHMB (Biguanides) Phosphate Sodium Hypochlorite PoolDirect 9 in 1 The principle When specific reagents are added, the water sample takes on a degree of coloration that is proportional to the concentration of the parameter being measured. The photometer measures this coloration. When a light beam passes through the coloured sample, energy with a specific wavelength is absorbed by the test substance. The photometer determines the coloration of the sample by measuring the transmission or absorption of light of this wavelength (in other words, monochromatic light). The photometer then uses a microprocessor to calculate the required concentration and displays the result.

36 The MD 100 uses high quality interference filters with long-life LEDs as a light source in a transparency sample chamber. The units supply accurate, reproducible results very quickly. Other major advantages include ease of operation, ergonomic design, compact dimensions and safe handling. Using an internal ring memory the last 16 data sets are stored automatically with date, time, parameter and measurement value. The tests are conducted using either Lovibond tablet reagents with long-term stability and a guaranteed minimum 5 or 10 year shelf life, VARIO powder reagents or using liquid reagents. Scroll Memory To avoid unnecessary scrolling for the required test method, the instrument memorizes the last method used before switching off the instrument. When the instrument is switched on again, the scroll list comes up with the last used test method first. Zero Setting (OTZ) For certain versions of the instrument it is not necessary to zero the instrument each time. The zero setting is held in memory until the device is turned off (One Time Zero - OTZ). The zero setting can be confirmed whenever it is usefull.

Technical data identical with PoolDirect, see page 45 Optics Twin light-beam technology guarantees optimum precision with PoolDirect photometers. With this system, the wavelength of a light beam is generated by an LED and fine-tuned through an interference filter. This light beam is then split via a semi-transparent mirror into a measurement beam and a reference beam. The light intensity of these two beams is measured by two different detectors. The reference beam strikes the detector directly, while the measurement beam first passes through the sample, before it strikes the second detector. The measurement figure is arrived at by calculating the difference in light intensity of the two beams and this means that only the absorption in the sample is measured. Any interference factors are automatically eliminated.

49 Reagents History For more than thirty years, Tintometer has been manufacturing reagents for water testing and marketing these reagents around the world under the brand name Lovibond. Different forms of reagents are required for different fields of application. It is fair to say that, in terms of quality, tablet reagents are the best form of reagent. Thanks to production techniques of the type used in the pharmaceutical industry and stringent internal quality standards, Tintometer is able to produce tablet reagents for water testing with a guaranteed shelf life of 5 or 10 years. These tablets are individually sealed in high-grade, polyethylene-coated aluminium foil and represent the reagent form of choice for everyday water testing applications. Users in different countries traditionally prefer forms of reagent other than tablets. Lovibond powder reagents are designed to allow fast and easy testing. Powder reagents are packed in aluminium foil for a wide range of applications and producers represent an alternative reagent form recently introduced by Tintometer. Last but not least, liquid reagents are indispensable for many testing tasks. Testing for substances that are hard to detect, for parameters like total nitrogen, or for the aggregate parameter COD, require the use of a wide range of reagents in a form that permits more "aggressive sample processing. The Lovibond programme is rounded off by reagent tests and tube tests, making Tintometer GmbH the only reagent producer in the world that offers a complete range of reagent forms. DPD Reagents DPD reagents are offered by different manufacturers. For quality reasons, users should validate the products prior to use. DPD reagents are produced on the basis of international standard methods, e.g. ISO 7393/2. The chemicals are of crystalline white nature. If a reagent (tablets or powder) is not white but has turned to grey/brownish or purple colours, it has deteriorated. DPD liquid reagents which should be colourless when fresh, may turn into brownish colour if the reagent has deteriorated. The use of such degraded products must be avoided as they will give false results. Tablets Our test tablets are manufactured in Germany under tightly controlled conditions on the latest machinery. Maintaining the highest quality standards permits Tintometer GmbH to guarantee our reagent tablets for a minimum of 5 years, and some for as long as 10 years. We can make this promise because each tablet is hermetically sealed within an individual aluminium foil pocket, protecting against challenging environmental conditions. This packaging keeps each tablet in perfect condition, right up until the time it is needed by the user. Test tablets remain the most consistent and reliable reagent format available, consistently outperforming other reagent formats, and delivering maximum accuracy for the user. Now we have improved even further on this highly successful format. To the tight quality control processes, integral to Lovibond s tablet manufacture, and the simple test procedures, we have added new blister packaging. Our new aluminium foil blister packaging brings added convenience to the tradition of protection achieved in Lovibond s long established tablet production technology. With the new blister strip, the user just pushes the tablet through the protective foil, straight into the sample. Simple, time-saving and practical. This type of packaging, long established in pharmaceutical applications, combines all the advantages of protective foil, with convenience for the user. Each tablet is contained within an individually formed foil cup, lined with the latest aluminium composite material, and guaranteeing product performance. As a result of improved sealing efficiency, the blister pack has been reduced in size to 91 x 34mm making them even more convenient for storage and shipping. BT is added to the end of the code to identify the new style of packaging. (For example BT). There are no safety risks if the tablets are used in line with the instructions supplied. Safety data sheets are available for all reagents. Specification and Certificate of Analysis To express the high quality standard of Lovibond tablet reagents, specification for each type of tablet as well as a Certificate of Analysis for each lot is available in the down-load area at 48 Regularly updated information: Pool & Spa Water Testing March 2011

50 Determination of Chlorine, Chlorine Dioxide, Bromine and Ozone with Lovibond Tablet Reagents Liquids As a rule, liquid reagents do not consist of a single preparation but comprise several components that need to be added to the sample in a certain order. As both the size and the number of drops have a decisive effect on the resultant colour complex, the reagents need to be added with a high degree of precision. The useful life of liquid reagents is reduced by temporary contact with oxygen in the air when the bottle is opened as well as by unsuitable storage environments (presence of sunlight or high temperatures). Provided that the bottles are stored within the temperature range +6 C to +10 C, the Lovibond DPD and Phenol Red solutions can be used for a period of one year from the production date. VARIO Powder Packs The fast and easy use of VARIO Powder Packs has made them extremely popular for water testing applications in many countries throughout the world. The Lovibond Powder Pack programme provides more experienced users with a real alternative to existing measurement systems. The Vario Powder Packs are produced to the same high quality standards that have made Tintometer's tablet reagents so successful for several decades. Parameters from aluminium and chlorine through to sulphate are just some of the well-known tests that are included in the VARIO Powder Pack range. Their chemical properties is suitable also for use with Hach-Photometer-Systems.

Advantage removes turbid materials from samples 0.45 µm mesh meets the requirements of the official German unitary procedure for water testing To prevent the effects of light scatter, it must be ensured that all turbid materials are removed from the sample before photometric measurements are carried out. This can be achieved with the Lovibond membrane filter set. Order code: (covers 25 x 0.45 µm membrane filters and two 20 ml syringes) Photometry Pool & Spa Water Testing March

57 Photo: swimming-teich.com Natural Swimming Ponds A natural swimming pond looks like a natural garden pond, but is specifically designed to swim in clean, pure water with no chemicals in it. The difference between a swimming pond and a swimming pool is that a swimming pool uses chemicals such as chlorine to kill bacteria, whereas a swimming pond cleanses the water naturally. It uses the purifying properties of plants, a filter to extract surface debris such as leaves, and a pump to keep the water circulating through the planting area. Nevertheless, the water quality has to be checked regularly to make sure that the bathers are safe under all circumstances, e.g. microorganism and other biological, chemical and physical components.

58 Microbiological, chemical and physical quality criteria Water quality includes all physical, chemical and biological factors that influence the beneficial use of water. There are many water quality variables in natural swimming ponds and bathing water in general. These are the most important criterias: Microbiology Escherichia coli Enterococci Pseudomonas aeroginosa Legionella pneumophila Cyano bacteria Parasites e.g. Cryptosporidia Photo: Schwimmbad & Sauna / Grafinger Chemical and physical characteristics Dissolved Oxygen Dissolved oxygen is probably the most critical quality variable in the water. Oxygen levels in pond systems depend on water temperatures, the water salinity, and the amount of aquatic vegetation and animals. ph-value The ph-value is the determination of the hydrogen ion (H + ) concentration in water. The ph scale ranges from 0-14 with a ph of 7 being neutral. A ph below 7 is acidic and an ph of above 7 is basic. An optimal ph range is between 6.5 and 8.5, however it should not be lower than ph5 or above ph9. ph will vary depending on a number of factors. The ph may rise during the day as phytoplankton and other aquatic plants remove CO 2 from the water during photosynthesis. The ph decreases at night because of respiration and production of CO 2 by organisms. The fluctuation of ph levels will depend on algae levels as well. Temperature Temperature will affect all chemical and biological processes. Temperature therefore has a direct effect on important factors such as growth and oxygen demand. The higher the temperature, the greater the requirement for oxygen and the faster the growth rate of the plants. Ammonia Ammonia is produced from the decomposition of organic wastes resulting in the breakdown of decaying organic matter such as algae and plants. Ammonia levels will depend on the temperature of the water and its ph. For example at a higher temperature and ph, a greater number of ammonium ions are converted into ammonia gas thus causing an increase in toxic ammonia levels within the freshwater. Nutrient levels Nutrient levels refer to the amount of phosphorus and nitrogen that are present in the water. Increased levels of nutrients may be harmful. It can cause excessive plankton growth, potential blue-green algae and oxygen depletion. Turbidity page 64 Test methods for a.m. parameter see index page 66 and 67. Natural Swim.

65 Turbidity Measurement The term "turbidity is used to describe the cloudiness or milkiness of water. In physical terms, turbidity is due to particles of varying sizes scattering or absorbing light, giving the water in question a cloudy appearance. This turbidity is caused by suspended particles such as sludge, limestone, yeast or microorganisms. The phenomenon of turbidity is measured using optoelectronic meters. An artificial light source emits a known intensity of light through a sample. The suspended particles scatter or absorb the light. The scattered light is then recorded on a photodetector. Scattered light is generally measured at an angle of 90. This measurement principle is known as nephelometry. Photo: Schwimmbad & Sauna The results are expressed in terms of FNU (Formazin Nephelometric Units) - identical with NTU (Nephelometric Turbidity Units). with infra-red light source (EN ISO 7027) The compact Lovibond infrared turbidity meter TurbiCheck is designed to allow fast, precise onsite testing. The unit measures the scattered light at an angle of 90, as stipulated in EN ISO The wide measuring range from TE/F = NTU = FNU makes the instrument suitable for various applications, ranging from drinking water to waste water. As infrared light is used for measurement purposes, the unit can be used to test both coloured and colourless liquids.
