Overview of Sodium Hypochlorite Generators

A Sodium Hypochlorite Generator (SHG) is an on-site system designed to produce sodium hypochlorite solution, commonly used for water disinfection and sanitation. By generating hypochlorite in real-time, these systems provide a safe, reliable, and cost-effective alternative to transporting concentrated chlorine chemicals.

Modern SHGs are engineered for continuous operation, optimized for energy efficiency, and adaptable to various water treatment scales, including municipal waterworks, industrial facilities, and wastewater plants. Their modular design enables flexible installation and straightforward maintenance.


Working Principle and System Design

Sodium Hypochlorite Generators operate based on the electrolysis of brine (saltwater), converting sodium chloride into sodium hypochlorite through an electrochemical reaction. The main components include:

  • Brine tank and dosing pump
  • Electrolytic cell for chemical conversion
  • Control system for monitoring and automation
  • Product storage tank
  • Safety and flow monitoring devices

The electrolysis process ensures precise control over concentration levels, producing consistent hypochlorite solution suitable for immediate water treatment applications. Advanced units include automated cleaning cycles to minimize downtime and extend equipment life.
