Explanation

Membrane electrolysis sodium hypochlorite generator is a suitable machine for drinking water disinfection, wastewater treatment, sanitation and epidemic prevention, and industrial production, which is developed by Yantai Jietong Water Treatment Technology Co., Ltd., China Water Resources and Hydropower Research Institute, Qingdao University, Yantai University and other research institutes and universities. Membrane sodium hypochlorite generator designed and manufactured by Yantai Jietong Water Treatment Technology Co., Ltd. can produce 5-12% high concentration sodium hypochlorite solution with a closed loop of producing fully automated operation.

Working Principle

The basic principle of electrolytic reaction of membrane electrolysis cell is to convert electric energy into chemical energy and electrolyze brine to produce NaOH, Cl2 and H2 as shown in the above picture. In the anode chamber of the cell (on the right side of the picture), the brine is ionized into Na+ and Cl- in the cell, wherein Na+ migrates to the cathode chamber (left side of the picture) through a selective ionic membrane under the action of charge. The lower Cl- generates chlorine gas under anodic electrolysis. The H2O ionization in the cathode chamber becomes H+ and OH-, wherein OH- is blocked by a selective cation membrane in the cathode chamber and Na+ from the anode chamber is combined to form product NaOH, and H+ generates hydrogen under cathodic electrolysis.

Application

● Chlorine-alkali industry

● Disinfection for water plant

● Bleaching for clothes making plant

● Diluting to low concentration active chlorine for home, hotel, hospital.
