Electrolyzer is used for different operations such as Brine water purification (Drinking water, swimming pools), Sea water bio-fouling etc. For Brine water purification, there are two types of electrolyzer. They are batch type and continuous type. In batch type monopolar and bipolar technology are used. In continuous type Concentric Tubular Electrode Technology, Parallel Plate Electrode Technology, Plate, Mesh Electrode Technology are used. For sea water bio-fouling (500 ppm - 2000 ppm) Parallel Plate Electrode Technology, Parallel Plate & Mesh Electrode Technology, Concentric Tubular Electrode Technology are used.
