Full Automatic Brine Electrolysis Sodium Hypochlorite Generator
0.8% Sodium hypochlorite generation system is producing sodium
hypochlorite onsite through 3% brine electrolysis(salt and water
after saturated), and the whole system is a combination of
Softening unit, Filtration unit, Salt dissolving unit, Online
proportioning unit, electrolytic unit, rectifier power supply,
automatic control systems, storage and dosing unit, etc.
Sodium Hypochlorite is widely used in many water industries. The
most applied in drinking water disinfection, on site generation of
Sodium hypochlorite is more safely than feeding chlorine gas.
Transporting Chlorine gas tank is risky to leakage and lead to
The sodium chloride contained in seawater or brine flow between
sets of electrodes (anodes and cathodes) in an electrolyzer.
The chemical reactions which take place in the electrolyzer between
chlorine and Sodium hydroxide produced by electrolysis.
In the electrolyzer the sodium chloride is completely dissociated
into the ions Na+ and Cl-, causes the following electrochemical and chemical reactions:
at the anode: 2Cl- - 2e → Cl2；
at the cathode: 2H+ + 2e → H2；
2NaOH + Cl2 → NaCl + NaClO + H2O
Overall reaction as follow:
NaCl + H2O + DC →NaClO + H2↑
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
Siemens Touch Screen
All running status are shown clearly and all parameters can be
adjusted directly by the touch screen.
Every step of process and protection of components is detected and
controlled by the smart PLC center, safety, reliability.
High frequency, stability and constant current rectifier.
Electrical conversion effciency over 90%
The rectifier have multiple protection for input over/under
voltage, and output overvoltage / overcurrent / short circuit
protection as well as overheat protection, ensure high reliability
Seko Metering Pump
Real-time detect residual chlorine in water, thus convert to 4-20mA
signal and feedback to PLC, for controling the dosing rate of
1) The only raw material: salt or sea water which is safety and
convenient for transportation and storage, without any volatility
2) Bipolar electrode connection mode, reduced the heat yield, as
well greatly reduced the production of sodium hypochlorite salt
consumption and power consumption
3) Salt consumption< 3.5kg / kg Cl2 (National standard 4.5);
power consumption < 4kw /kg Cl2 (National standard 4.5)
4) Siemens PLC and touch screen, full automatic control
5) Cathode life >20 years; Machine life >15 years
