In case of any doubt contact your distributor or BSV Electronic S.L. We would be delighted in helping you. 1. GENERAL DESCRIPTION Thank you for selecting our salt water chlorinator BSPOOL, That will makes you fully enjoy your swimming pool in perfect conditions, without the need of adding any disinfectant or chemical product. The salt water chlorinators of BSV Electronic S.L. keep the water clean without adding chemical disinfectants. Salt water chlorination produces chlorine by means of electrolysis of slightly salt water. “Free chlorine” (hypochlorous acid, HOCL) is produced, which is a strong bactericide. An important characteristic of the system is that it is reversible, that is, after oxidising the bacteria, chlorine reverts back to common salt and water. It is not necessary to add any chemical product (algaecides, cyanuric acid, etc.) which helps in keeping the water unpolluted. It is not necessary to control the chlorine level: it is kept constant automatically if the KIT REDOX PROBE is installed (OPTIONAL) . Chlorine excess, causing irritation, or chlorine defect, causing infections are avoided. Slightly salt water is healthier than pure water: the skin wrinkles less and eye irritation is reduced. The equipment is made of an electronic control unit and an electrolytic cell through which runs the pool water. Expenses and maintenance time are drastically reduced with the salt water chlorinator. If the chlorinator is kept working permanently, it will not be necessary to replace the water for many years (8 to 15 years depending on use), and you will collaborate with the politics of water savings. Manual Concept-k, ver 2 3 / 34 ________________________________________________________________ 1.1.1. “ORP” (“Redox”) control optional OPTIONAL The unit measures continuously the bactericide power of the water (free chlorine level) by means of an ORP sensor. Once the desired level is set, the unit keeps it automatically, controlling chlorine production according to swimming pool conditions. The display shows the ORP (or Redox) level of the water. The ORP (oxidation-reduction) or Redox potential is a measure of the oxidising or reducing strength of a solution. In the case of the swimming pools, it is related directly with the biocide power of the water. ORP is more reliable than colorimetric reactive (DPD) in measuring disinfecting water power and measures it with enough independence of pH level; so it has been adopted by the majority of Health Authorities for the control of drinking water and swimming pools. As an example, the E. Coli bacteria may survive 5 hours at 450 mV ORP but only 1 second at 650 mV. Salmonella dies also fast at 650 mV. 650 mV may be enough for private swimming pools of moderate use. For public swimming pools, a 720 mV level is considered to be ideal. Fungi and algae spores need a higher level. In conventional systems a “super chlorination” from time to time is recommended to kill them. But one of the advantages of the salt water chlorinator is that the pool water runs inside the chlorinator electrodes, where the chlorine level and thus the ORP potential are very high, killing algae and fungi. “Super chlorination” is not necessary, nor algaecides or other chemical products that deteriorate water quality. And a last remark: “chlorine smell” does not mean normally that there is too much chlorine, but that chloramines have been produced by lack of chlorine. Control through free chlorine probe The amperometric analysis consists in measuring the intensity of the voltage caused by the reaction of the reduction or oxidation of a reagent when you use an appropriate electrical potential. The intensity of the voltage is proportional to the quantity of hypochlorous acid that is in the solution. Take into account that the hypochlorous acid is a weak acid so the distribution of its atoms depends on the pH of the environment. Both hypochlorous acid and hypochlorite react to the working potential of the sensor. That is why it is advised to compensate the reaction of the sensor according to de pH level of the environment by a ph from 7.0 to 7.4. Under or over those pH values, other reactions can interfere on the electrode surface and prevent the correction of the previous interpretation. Manual Concept-k, ver 2 4 / 34 ________________________________________________________________ 1.1 Safety 1.1.2. To avoid abnormal working conditions, the control unit measures continuously the electrolysis parameters and the state of the electrolysis circuit so that if the water flow is too low in the cell, or if there is a short-circuit or an overload in the cell, the power circuit disconnect automatically activating a lighting and acoustic alarm until the problem is solved. After a while, the device restarts automatically. 1.3 Technical characteristics: • Supply voltage: 230VAC/ 50Hz. • Consumption: Model 20Gr/h 25Gr/h 35Gr/h Power 150W 190W 262W Consumption 0,7A 0,86A 1.2A • Max. cell tension: 7,5 Vcc • Insulation voltage according to EN 609050: 3000 Vac • Control of chlorine production with a switched mode power supply. • Efficiency > 90%. • Stops in case of lack of water flow. • Stops in case of too much gas in the electrolysis cell. Automatic restart when the water flow is restored. • Lack of salt warning. • Excess of salt warning. • Automatic control of the voltage in function of the salt level and the temperature, keeping chlorine production constant • Chlorine production level indicator. • Automatic control of chlorine level. • Automatic or manual operation (with/without ORP sensor). • Surge indicator and protection stopping the power output with automatic restart (1 minute). • Acoustic alarm. Manual Concept-k, ver 2 5 / 34 ________________________________________________________________ • Water temperature indication (optional). • Internal temperature control • Non volatile memory (EEPROM) keeps data permanently. • Automatic electrode cleaning cycle. Every 8 hours. • Automatic restart after power supply loss. • Working hours counter. 2. SWIMMING POOL PREPARATION It is necessary to add some salt to the water and ensure that the pH level is adequate. pH and salt levels have to be as follows: pH -------------------------- 7,0 to 7,4 Salt, kg/m3 -------------- 2* to 6,5 * The device starts working from 2gr/L. Nevertheless, the chlorine production will not reach 100% until the salt level dissolved in the water is 4gr/L. Chlorination efficiency and water quality for a healthy bath depend of the water pH, so it is important to control it regularly and adjust it when necessary. If you do not want to be pending of pH control, you can acquire one of our pH automatic controllers, shown in our catalogue, which can be included in the chlorinator. Chlorination efficiency and water quality for a healthy bath depend of the water pH, so it is important to control it regularly and adjust it when necessary. If you do not want to be pending of pH control, you can acquire one of our pH automatic controllers, shown in our catalogue, and that can be included in the chlorinator. In principle a better disinfection efficiency is obtained if pH is low (acid) but a too much low value can cause irritation and corrosion problems. Try to keep it from 7,0 to 7,4. To compute the quantity of salt needed, multiply the water volume in cubic meters by 4.5 … 5.5. EXEMPLE: Swimming pool 9 m long, 4.5 m wide, 1.6 m average depth: 9 x 4,5 x 1,6= 64,8 cubic meters 64,8 x 4,5 = 291,6 kg of salt (Note: 4,5 is the quantity of salts x m3) We advise to use salt specially prepared for swimming pool chlorinators, as it is designed to facilitate the dissolution and obtain optimum results in your installations. It is available in shops specialized in swimming pool products.

  • Section 5 – Water Quality and Testing
    SECTION 5 – WATER QUALITY AND TESTING Maintaining water quality is a fundamental role in operating an aquatic facility. The objectives of an operator should be to: • Ensure the water is properly disinfected at all times, to prevent transmission of infectious diseases, • Achieve maximum patron comfort, and • Maximise longevity of the facility structure. Whenever an aquatic facility is available for use, the water needs to contain an adequate level of a chemical that can destroy micro-organisms. By far the most common chemical used for disinfection is chlorine. This material has the advantages of being a relatively low cost, highly effective disinfectant that is readily available. However, chlorine is also a highly reactive chemical, which non-selectively combines with nitrogen-rich pollutants in the water, to produce unwanted chemicals known as chloramines. These give the water a characteristic pungent chlorine-like smell, and irritate the eyes and skin of patrons. Chloramines are also known to be less effective disinfectants than free chlorine. High concentrations of chloramines reduce the overall effectiveness of the chlorination process. The chloramine problem is generally worse in heavily patronised facilities, where patrons add large amounts of urea and other nitrogen-rich bodily wastes to the water. A number of technologies are now available to reduce the levels of chloramines in water. Examples include the use of ozone gas, ultraviolet light irradiation, and the addition of non-chlorine oxidising chemicals to the water. The use of these technologies should be considered for indoor aquatic facilities with significant bather numbers. Chlorine also undergoes significant degradation when exposed to sunlight.

  • Pool Chemical Information
    Pool Chemical Information Acid o Acid is used mainly on salt pools to lower the pH. When the pH and alkalinity are out of balance, the chlorine is significantly less effective. The pH should be balanced between 7.4-7.6. Chlorinating with a salt water chlorinator produces a high pH (11.8). Without a weekly dose of Acid, salt systems will increase the pH to 7.8-8.2 or greater. A high pH can cause the pool to scale, and the chlorine would be locked up by the basicity. Without the use of Acid the pH can potentially ruin the salt cell in a few months. Algaecide o Algae are a microscopic single cell plants. While they are not directly harmful or toxic, they are unattractive in swimming pools since they discolour the water, usually green, which is unpleasant for swimmers. The vinyl can also become slippery if algae are stuck to it. As they are plants, they bloom in the same conditions as plants do. They require nitrogen, phosphorus and potassium. They also like sunlight as it is essential for photosynthesis. This is where chlorophyll, which causes the green colour, utilises light energy and converts carbon dioxide into organic compounds essential for growth while releasing oxygen. Nitrogen is usually introduced into the water by bather contamination. Algaecide is the strongest available chemical we have, in conjunction with granular chlorine, to fight against algae break outs. This product can be used as a weekly preventive measure or as a concentrated dose to remove visible algae. There are more concentrated and less concentrated forms of the product depending on situation.

  • The Chemistry Involved in Maintaining a Saltwater Pool
    Joel Johnson, Yr 12, Chemistry ERT 3.1 Final, 11/4/16 Page 1 of 16 The Chemistry Involved in Maintaining a Saltwater Pool Introduction Although many people have chosen to switch to a saltwater pool, under the impression that they are maintenance free, this is not the case. Despite the fact that equilibria reactions in the pool minimise the amount of maintenance required, chemicals still need to be added regularly to keep the pool clean and hygienic. This report outlines the chemicals and equipment necessary to maintain a saltwater pool, and examines the various chemical reactions that occur in the pool. Alternative sanitisation methods and the amount of each chemical required to set up a new saltwater pool are also discussed. Discussion Chemicals and Equipment Required to Maintain a Saltwater Pool It is essential to maintain appropriate levels of various chemicals in a pool in order to kill pathogens and maintain chemical balance. One of the most important chemicals in a pool system is hypochlorous acid, which is a powerful disinfectant. In a saltwater pool, the chlorine generator converts chloride ions into chlorine gas, which in turn forms hypochlorous acid when it dissolves. The chlorine generator needs a relatively high concentration of chloride ions to operate, so a large amount of sodium chloride (NaCl) is initially added to the pool. After this, sodium chloride only needs to be added occasionally, as the chloride is recycled within the pool system. Hypochlorous acid is rapidly broken down by UV radiation, so the stabiliser isocyanuric acid (C3H3N3O3) is used to reduce the effects of sunlight.
