500g/h Sodium Hypochlorite Generator From Electrolysis 2.5% - 3% Dilute Saline Water

500 g /h Water Treatment System from Electrolysis 2.5% - 3% Dilute Saline Water

Product introduce

Sodium hypochlorite generator is a generator to produce sodium hypochlorite by brine or sea water electrolysis, and the whole system is a combination of softener, salt dissolving unit, brine proportion unit, control system, electrolytic unit, storage unit, dosing unit and acid washing unit. It's a system using salt as raw material to produce sodium hypochlorite liquid (0.8%) and dose into water for disinfection.

Principle

Electrochlorination uses electricity to convert SALT + WATER (brine) into a mixed oxidant solution of sodium hypochlorite and hydrogen peroxide.

Evenly spaced titanium electrodes are placed in a 3% brine solution (NaCl + H2O). When a DC current is applied to the electrodes the brine acts as a conductor between the positive and negative poles. The resulting electrochemical reactions convert the brine into the sodium hypochlorite based mixed oxidant solution.

The electrode reaction and solution reactions is

Electrode reaction:

at the anode: 2Cl- - 2e → Cl2；
at the cathode: 2H⁺ + 2e → H₂；

Solution reaction:

2NaOH + Cl₂ → NaCl + NaClO + H₂O

Overall reaction as follow:

NaCl + H₂O + DC →NaClO + H₂↑

Feature and Benefit

♫ Eliminates hazards associated with gaseous Cl2. More stable than bulk sodium hypochlorite.

♫ Safe and clean on-site production.

♫ Safe and economical using only salt, water and electricity.

♫ Eliminate transportation and handling of gaseous chlorine or bulk sodium hypochlorite.

♫ Skid mounted, fully integrated systems.

♫ Automatic, local or remote operation.

♫ Easily integrates with all chlorine analyzers and dose control systems.

♫ Stable and repeatable levels of free chlorine at the end of your distribution system.
