Water Decontamination System
(Electrolytic system for chlorine generation from salt)
According to the technical regulations of drinking water, the content of residual (active) chlorine in water should be within the range of 0.3-0.5 mg/l. It is known that the water received through ultrafiltration is free from any microbiological contamination. Nevertheless, the residual chlorine is essential in such water as it is supplied to the tanks where bacteria, fungi and viruses multiply very rapidly in wet conditions, especially in summer periods. The estimated chlorination value is set at 1 mg/l, as chlorine may react with existing impurities, while the amount of the residual chlorine will be decreased inevitably. If we determine the degree of chlorination by this value, then the 50g hourly dose of the active chlorine will be required. This is due to the supply of large amounts of sodium hypochlorite. For example, if 5% solution is purchased, then almost 25 liters of hypochlorite per day will be needed. You can not trust the purchased solutions, because the concentration of chlorine decreases sharply over time.
It is therefore more convenient to generate chlorine from table salt on the spot. The picture shows the regeneration system of sodium hypochlorite from salt (manufacturer - Ecopre Ltd).
