Sodium hypochlorite – NaOCl is an inorganic chemical compound with a characteristic sharp odor of chlorine. In its free form, it is very unstable and is therefore mainly used in aqueous solutions with concentrations of up to 20%. Sodium hypochlorite has strong oxidizing properties. It can be produced by electrolysis of sodium chloride solution or by adding chlorine to caustic soda.
Water disinfection using sodium hypochlorite is a commonly used method due to for ease of dosing and the availability and low price of sodium hypochlorite on the market. The use of this disinfectant reduces the risk of secondary contamination of water supply networks.
Generating sodium hypochlorite at the dosing point has two main advantages – firstly the solution produced has a much lower concentration, thus avoiding problems related to dilution, and secondly Only as much sodium hypochlorite is produced as is required for disinfection. We do not lose the active substance and we do not have storage problems. We are sure that the sodium hypochlorite we dose is always fresh and has the appropriate effectiveness.
Sodium hypochlorite generators They operate on the basis of the salt electrolysis process. The reactor in which the disinfectant is produced is made of electrodes – an anode and a cathode. During the flow of brine of the appropriate concentration through the reactor, while supplying direct current to the electrodes, the electrolysis process takes place, as a result of which sodium hypochlorite and hydrogen gas are produced, which must be removed outside the building.
NaOCl MC generators are available in eight models, differing in performance – from 240 to 8500 g Cl2/h.
