KALF ENGINEERING PTE LTD is the leading manufacturer of on-site Seawater Electrochlorination system for a long time, Seawater is the only consumables apart from the electricity.
Depending on the application and the site special needs, elysisPURE seawater based electro-chlorinators can be a skid-mounted or a component-based system. The skid-mounted systems are smaller, requiring less space.
Seawater is injected into the electrolyser. The solution is then electrolyzed with direct current (DC power).
The anode produced is chlorine gas and the cathode produced is sodium hydroxide and hydrogen. These two substances react with each other to form a sodium hypochlorite solution.
KALF’s elysisPURE seawater electro-chlorinators have demonstrated reliable and economic operations with low maintenance requirements in numerous installations throughout the region.
The elysisPURE seawater electro-chlorinators have been used for biofouling control in power plants, cooling towers, liquefied natural gas (LNG) terminals, offshore platforms and desalination facilities, as well as coastal installations using seawater for cooling and other processes.
This reaction can be simplified in the following manner:
Seawater + Energy = Sodium Hypochlorite
Softened water + Salt + Energy = Sodium Hypochlorite OR
NaCl + H2 O + DC Supply = NaOCl + H2
