How On-Site Sodium Hypochlorite Generation Works
An on-site NaOCl system converts prepared chloride feed into active chlorine using an electrolytic cell and controlled DC power. The complete process also requires feed preparation, gas management, controls and downstream product handling.
Water & Salt Preparation
High-purity salt and softened water are prepared into a controlled brine solution.
Controlled Feed to Electrolyzer
Brine is metered at a specific flow rate to maintain stable electrolysis conditions.
Electrolysis
DC power drives the reaction across MMO titanium electrodes within the cell.
Active-Chlorine Product Stream
Chlorine reacts in solution to form dilute sodium hypochlorite (NaOCl).
Gas Management & Dosing
Hydrogen is separated and vented, while NaOCl is stored and dosed as needed.
Safety Note: Hydrogen handling is a system-level safety requirement. Ventilation, dilution, gas separation, monitoring and interlocks must be designed according to the actual system and site requirements.
Choose Brine-Based or Seawater-Based Generation
The right sodium hypochlorite generator depends on your feed source, salinity, water quality, output concentration, installation environment, and disinfection objective. Hele Titanium helps you select and engineer the system architecture that fits your site.
Brine-Based Sodium Hypochlorite Generators
Best For: Municipal water, wastewater, cooling towers, industrial process water, commercial facilities, and sites without seawater access
How It Works: High-purity salt and softened water are prepared into brine and electrolyzed into dilute NaOCl.
- Controlled feed chemistry
- Stable output concentration
- Suitable for inland facilities
- Easier scaling control with proper water softening
- Broad municipal and industrial use
Seawater Electrochlorination Generators
Best For: Coastal power plants, desalination plants, offshore platforms, vessels, marine cooling systems, and biofouling control
How It Works: Filtered natural seawater is electrolyzed directly to generate active chlorine species.
- No prepared salt brine required
- Ideal where seawater is naturally available
- Effective for continuous biofouling control
- Suitable for marine and coastal infrastructure
What’s Inside a Complete Sodium Hypochlorite Generator?

How to Size an On-Site Sodium Hypochlorite Generator
The correct system capacity depends on daily chlorine demand, target available chlorine concentration, treatment flow, operating hours, salt and water quality, power supply, and dosing strategy.
| Selection Factor | Buyer Question | Why It Matters |
|---|---|---|
| Daily Chlorine Demand | How many kg/day of available chlorine are required? | Determines system output size. |
| Target NaOCl Concentration | What solution strength is required? | Affects electrolysis design, storage, and dosing logic. |
| Water Flow | What is the treatment flow rate? | Supports dosing calculation and system capacity planning. |
| Operating Hours | Continuous or batch operation? | Affects equipment sizing and daily production planning. |
| Salt and Water Quality | What salt and water source are available? | Affects brine stability, scaling risk, and maintenance. |
| Power Supply | What voltage, phase, and frequency are available? | Affects rectifier and control cabinet design. |
| Storage and Dosing | Is storage tank and dosing pump integration required? | Determines complete system scope and installation planning. |
