Brine electrolysis Onsite chlorination equipment of sodium
It is a proven technology to convert ordinary salt (common salt) or
sea water, by means of electrolysis into sodium hypochlorite
(ELECTRO HYPO) using GEEMBLUE sodium hypochlorite generators
(electro chlorination system). It is always applied on-site, at the
point of application. No chemicals other than ordinary salt are
used throughout the process.
The electrolytic cell is fed a DC current from the rectifier and
electrolyzes the diluted brine into sodium hypochlorite solution.
Chlorine evolves at the anode surface, while hydrogen and hydroxide
evolves at the cathode surface. The secondary reaction of chlorine,
sodium and the hydroxyl ion nets sodium hypochlorite (chlorine
bleach) at a 0.8% solution. Below 1%, hypo is classified as a
non-hazardous chemical although still a very effective
disinfectant. The only by-product, hydrogen, is safety vented into
Electrolysis Reaction Equation
NaCl + H2O + DC → NaClO + H2
Anode: 2Cl- - 2e- → Cl2
Cathode: 2H2O + 2e- → H2 + 2OH-
2NaOH + Cl2 → NaCl + NaClO + H2O
1. Inﬂuent water is passed through a water softener.
2. Using softened water to dissolve the salt in a tank to form a
concentrated brine solution.
3. Diluted into 2.5%-3% after filtered (If use sea water as raw
material, it will be treated before electrolysis)
3. The diluted brine is electrolyzed to a 0.8% solution of sodium
4. The 0.8% hypochlorite solution ﬂows into a storage tank.
5. The sodium hypochlorite solution will be injected into the pipe
by metering pump.
6. The residual chlorine detector will monitor residual chlorine
and return feedback to the PLC center.
7. According to preset standards, the PLC Center will adjust the
speed of the dosing pump.
Advantage of Geemblue Sodium Hypochlorite Generator
Safety Raw Material Added
No chemical required, salt and water only.
No Dangerous Goods Transportation
Chlorine dioxide chemical disinfection, one of the raw material
name "Hydrochloric acid" is dangerous material, which is restricetd
in the purchase, storage and transportation. Another disinfection
too. The on-site electrolytic sodium hypochlorite solution requires
only food grade salt which is known as human body needed everyday.
Full Automatic Running
Full computer program, PLC, online chlorine analyser, ensure the
residual chlorine in water and make use of every drop of liquid.
Safety Solution Produced
The final product, 0.8% sodium hypochlorite, is recognized as
On-site Generation And Dosing
Instead of high strength sodium hypochlorite solution which is
unable to store for long time.
Low Running Cost
3.5kg salt and 4KWH energy consumption for 1kg available chlorine.
Central control, able to remote control, the staff can operate
after simple training.
