Chlorinsitu - Model V - Electrolysis System
Output of 100 – 3,500 g ultra-pure active chlorine per hour. Generate ultra-pure active chlorine using the vacuum method with electrolysis system CHLORINSITU V. Suited to applications for metering hypochlorous acid and simultaneously correcting the pH value.
From cooking salt chlorine, hydrogen and sodium hydroxide are made. Directly on site.
Electrolysis systems of type CHLORINSITU V generate ultra-pure active chlorine in a vacuum process. 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 dilute residual brine are produced in the anode chamber, separated by the diaphragm from the cathode chamber. The active chlorine produced is suctioned off through an injector (contained 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. The chloride-free sodium hydroxide is stored temporarily and can be used forpH value correction. A standard diaphragm metering pump is first used to correct the base pH (pH 6.8 – 7) of the superchlorinated water. The fine correction of the pH value is provided via additional alkali metering pumps for each circuit or point of injection. These are connected directly to the system's control through an external pH value controller. The hydrogen produced is diluted with fresh air through an ATEX 95-approved fan and discharged safely. The diluted residual brine is fully discarded. To this end, the diluted brine is strongly diluted with softened water, neutralised by the addition of sodium hydroxide and disposed of in the sewer. All residual chloride and chlorate are thus disposed of and are not mixed with the process water. Electrolysis systems of type CHLORINSITU V 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, thereby preventing the formation of lime deposits and ensuring the long service life of the diaphragm cell. The efficiency of electrolysis is constantly monitored by various flow meters, the addition of water depending on the sodium hydroxide production and the base pH correction.
