0.7~0.9% sodium hypochlorite generation for tap water disinfection
Sodium hypochlorite generator summary
Sodium hypochlorite generator is a device to generate sodium
hypochlorite solution by brine or sea water electrolysis. Composed
of salt dissolving unit (If sea water, no needed), filter, diluting
unit (If sea water, no needed), electrolytic unit, rectifying power
supply, automatic control system, storage and dosing unit etc.
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:
NaCl + H2O + DC →NaClO + H2↑
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.
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.
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
