Seawater Electrochlorination

Seawater Electrochlorination

Seawater Electrochlorination Plants and packages are used in industries or water treatment plants that are taking water from seawater-intakes. By the electrolysis of Seawater through MMO Anodes and Titanium Cathodes, the Sodium Hypochlorite will be produced alongside Hydrogen gas. This technology makes you independent of industrial Sodium Hypochlorite, sometimes not available due to interruptions in supply chain. This solution could be used to sanitize water wherever you need disinfection. The chemical analysis of the water must be determined before any design.



  • Recording and Controlling inlet & outlet temperature, pressure, voltage, and amperage at electrolyzer
  • Dilution of air pressure and flow monitoring
  • Rupture disk applied at Electrolyzer inlet
  • Hydrogen detector
  • Air (Nitrogen) purging for H2 dilution and long-term shutdown
  • Liquid earthing


  • Horizontal electrolyzer
  • Full flow pass through Electrolyzer
  • Conductivity meter utilized in acid cleaning system
  • Use of digital multi-function meters for each MCC feeder

Environmentally friendly

  • Mist separator Easy Application and Long Endurance
  • HMI installation on Rectifier
  • Use of capacitor at rectifier inlet
  • Fluid velocity control and Sampling at each Electrolyzer outlet
  • Appropriate injection systems
  • Appropriate flushing system of injection pumps
  • Appropriate tank design

The graphical scheme of the process is shown herein. What is important is that we do the turnkey projects from feasibility study to design, installation and commissioning. All the accessories such rectifiers or pumps will be procured from our reputable vendors. What is different here compared to brine systems, is the acid washing systems. Obviously, the sea water circulation dictates the washing of the facilities regularly to avoid efficiency reduction.

Seawater Electrolysis ProcessIn ULTRANODE, we support a wide range of capacities to generate Sodium Hypochlorite for water disinfection applications. Also, the electricity, Salt and Water consumption is included. Significantly, the electrical consumption is among the bests in the market.
