Seawater Electrolysis
Seawater Electrolysis
Normally, seawater contains 18,980 mg/l of chloride ions and 10,561 mg/l of sodium ions. Using special electrodes to electrolyse seawater produces effective chlorine(includingHCIO、CIO-、Cl2), which is a broad-spectrum bactericide that kills bacteria and algae in seawater, thus preventing marine organisms from adhering to and growing on the inner wall of the pipeline.
Anode:
2Cl- → Cl2 + 2e
Cathode:
2H2O+ 2e → 2OH- + H2
Electrolyte:
Cl2+ H2O → HOCl + Cl- + H+
HOCl → H+ + OCl-
Application Area
Ballast Water Treatment

Discharge of ships' ballast water can cause the breeding of harmful aquatic organisms and the spread of pathogens, as well as triggering the invasion of xenobiotics, thus destroying the marine ecological balance. The International Maritime Organisation (IMO) has formulated and ratified the Ballast Water Management Convention, which requires ships' ballast water to be effectively treated before discharge.


Compared with UV technology, electrochlorination technology has become the mainstream technology for ballast water treatment due to its wide applicability, large treatment capacity and low energy consumption.

Anti-fouling by Seawater Electrolysis

Coastal power plants, chemical plants, offshore platforms and other facilities require large amounts of seawater as cooling water. Organic organisms in seawater often attach to the cooling pipe wall, forming biofouling, which affects the heat exchange efficiency and facility safety.


Seawater Electrolysis can effectively inhibit and prevent the adhesion and growth of sea organisms, and at the same time has the advantages of safety, convenience and low operating costs.
