Beverage Disinfection Sodium Hypochlorite Equipment of mmo Anode
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
Principle of sodium hypochlorite generator
Salt solution contains the several kinds of ions such as Na +, H -,
when electrolysis, under a certain voltage, as a result of the
movement of ions in the electrolyte solution and electrode
reaction, the conductive effect occurs, then CL -, OH - such as
negative ion to the anode, and positive ions such as Na +, H + to
the cathode, and the corresponding electrode discharge occurs, thus
carries on the REDOX reaction, the corresponding material
production. The electrode reaction and solution reactions is
anode: 2Cl- - 2e → Cl2；
cathode: 2H+ + 2e → H2；
2NaOH + Cl2 → NaCl + NaClO + H2O
Overall reaction as follow:
Na Cl + H2O + DC →NaClO + H2↑
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.
Transparent electrolytic cell, organic glass material.
TA1 titanium electrode, the anode is covered by ruthenium-iridium
oxide fine nano coating which is up to 20 layers, ensure more than
5 years service life.
Bipolar electrode connection mode, reduced the heat yield, as well
greatly reduced the production of sodium hypochlorite salt
consumption and power consumption, plays a positive role in
