Electrolysis Chlorine and sodium hydroxide are produced in-situ in electrolysis by passing an electric ... more in the glossary systems of type CHLORINSITU® V Plus generate ultra-pure chlorine gas combined with a sodium hypochlorite solution in a vacuum process Process which allows high-purity substances (e.g. active chlorine) to be generated through the absence of oxygen and other gases. more in the glossary. A saturated solution of sodium chloride is produced in a salt-dissolving tank, included in the scope of delivery, and this solution is then electrolysed in a diaphragm cell. Chloride-free sodium hydroxide and hydrogen are produced in the cathode chamber, while ultra-pure chlorine gas and diluted residual Describes the ability of a substance to have a long-term effect and ... more in the glossary brine are produced in the anode chamber, separated by the diaphragm from the cathode chamber. The resulting ultra-pure chlorine gas is further processed in two ways. Firstly, it is suctioned off through an injector (included in the scope of delivery) and fully dissolved as hypochlorous acid in the water being treated (through a bypass). The superchlorinated water is then distributed throughout the various pools via one or more proportionately controllable motor driven ball valves. The vacuum is kept stable by a single frequency-controlled booster pump. This permits significant savings in terms of energy. If the complete production output is not needed, excess chlorine gas can also be combined with the sodium hydroxide produced and then temporarily stored as sodium hypochlorite. The system thus does not have to be dimensioned according to the maximum chlorine gas demand rather according to the average daily demand. Peaks in demand are met by the additional metering of sodium hypochlorite from the temporary storage, which, as with hypochlorous acid, is fed through a central injector system.
The chloride-free sodium hydroxide is stored temporarily and can be used for pH value The pH value is a measure of the acidic or basic character of an aqueous solution. more in the glossary correction. First the base pH (pH 6.8 – 7) of the superchlorinated water is corrected by a standard diaphragm metering pump or through the addition of sodium hypochlorite. Fine correction of the pH value The pH value is a measure of the acidic or basic character of an aqueous solution. more in the glossary is achieved by additional alkali metering pumps for each circuit or point of injection. They are connected directly to the system's control through an external pH value The pH value is a measure of the acidic or basic character of an aqueous solution. more in the glossary controller. The hydrogen produced is diluted with fresh air through an ATEX 95-approved fan and discharged safely. The diluted residual Describes the ability of a substance to have a long-term effect and ... more in the glossary brine is fully discarded. To achieve this, the diluted brine is strongly diluted with softened water, neutralised by the addition of sodium hydroxide and disposed of in the sewer. Any residual Describes the ability of a substance to have a long-term effect and ... more in the glossary chloride and chlorate are thus disposed of and are not mixed with the process water. Electrolysis Chlorine and sodium hydroxide are produced in-situ in electrolysis by passing an electric ... more in the glossary systems of type CHLORINSITU® V Plus can thus be compared with pure chlorine gas in terms of their oxidation strength and chloride / chlorate content in the process water. The salt-dissolving water comes from a softener integrated in the system, preventing the formation of lime deposits and ensuring the long service life of the diaphragm cell. The efficiency of the electrolysis Chlorine and sodium hydroxide are produced in-situ in electrolysis by passing an electric ... more in the glossary is constantly monitored by various flow meters, the addition of water depending on the sodium hydroxide production and the base pH correction.
