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.
High-purity salt and softened water are prepared into a controlled brine solution.
Brine is metered at a specific flow rate to maintain stable electrolysis conditions.
DC power drives the reaction across MMO titanium electrodes within the cell.
Chlorine reacts in solution to form dilute sodium hypochlorite (NaOCl).
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.
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.
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.
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.
A reliable sodium hypochlorite generator requires more than an electrolytic cell. Each subsystem must work together to maintain stable output, safe hydrogen handling, accurate dosing, and long equipment life.
Removes calcium and magnesium hardness to reduce scale formation inside the electrolytic cell.
Value: Improves cell efficiency and reduces cleaning frequency.
Prepares consistent brine concentration for electrolysis.
Value: Supports stable NaOCl output and predictable system operation.
Delivers electrolyte at a controlled flow rate to the electrolytic cell.
Value: Maintains production consistency and protects system balance.
Converts brine or seawater into active chlorine using MMO-coated titanium electrodes.
Value: Determines system efficiency, service life, and output stability.
Provides stable DC current for electrolysis.
Value: Controls energy efficiency, current stability, and cell protection.
Stores generated dilute NaOCl solution before dosing.
Value: Provides buffer capacity for continuous disinfection demand.
Inject generated NaOCl into the target water stream.
Value: Supports accurate dosing based on flow or residual control.
Dilutes and safely vents hydrogen gas generated during electrolysis.
Value: Critical for safe system operation and compliance.
Automates operation, alarms, interlocks, monitoring, and data logging.
Value: Reduces operator workload and improves safety control.
Concentration basis: Specify whether the project requires dilute on-site NaOCl, active chlorine in a seawater stream or another defined product strength. A requested concentration, including 8%, is a separate engineering and safety review—not a standard output claim for every system.
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. |
