Disinfection Equipment
An on-site sodium hypochlorite generator produces a dilute chlorine disinfectant by electrolyzing a salt solution, avoiding the transport and storage of chlorine gas or concentrated bleach. It is used by drinking water plants, wastewater treatment plants, swimming pools, hospitals and industrial cooling water systems.

How it works
How disinfection equipment work
Softened water and food-grade or purified salt are mixed to make a brine, which is diluted and fed to an electrolytic cell. When direct current passes through the cell, chloride ions are oxidized at the anode to form chlorine, which immediately reacts in solution to form sodium hypochlorite. Hydrogen gas is produced at the cathode as a by-product and must be safely diluted and vented. The low-concentration hypochlorite solution, typically below 1 percent, flows to a storage tank. Dosing pumps then inject it into the water to provide disinfection and maintain a chlorine residual.
Selection guide
How to choose the right model
- 01
Chlorine demand
Size the generator on the flow to be treated and the required chlorine dose, expressed as available chlorine per hour or per day, including peak demand.
- 02
Salt and water quality
Salt purity and water hardness affect electrode life and scaling. A softener and suitable salt grade help protect the cell.
- 03
Hydrogen management
The system must safely separate and vent hydrogen. Check the degassing and ventilation design for the installation room.
- 04
Storage and dosing
Consider storage tank volume for buffering demand, the number of dosing points and how dosing will be controlled.
- 05
Maintenance and electrode life
Ask about electrode cleaning requirements, expected replacement intervals and the availability of spare cells.

FAQ
Disinfection Equipment: FAQ
Why generate sodium hypochlorite on site?
On-site generation avoids transporting and storing hazardous chlorine gas or concentrated bleach. It uses only salt, water and electricity, and the dilute product is more stable than commercial bleach.
What concentration does an on-site generator produce?
Electrolytic generators typically produce a dilute solution of below 1 percent available chlorine. This is lower than commercial bleach, so larger volumes are dosed.
Is the hydrogen by-product dangerous?
Hydrogen is flammable, so it must be separated, diluted with air and vented safely. A properly designed system includes degassing and ventilation for this purpose.
What kind of salt is required?
High-purity sodium chloride with low impurities is recommended to protect the electrodes. Feed water is usually softened to reduce scaling in the cell.
