The company has been focusing on serving municipal utility plants, sewage treatment plants, power plants, oil platforms, mariculture and food processing plants, etc. and providing quality water treatment equipment and water treatment solutions, so far, the company has been a business partner of many large environmental companies at home and abroad.
Generation principle:
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:
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↑
The process of the sodium hypochlorite generator
The operation of the Geemblue system is simple:
1. Salt Dissolving
Influent water passes through a water softener to reduce hardness therefore reducing the scaling of electrodes. Using softened water to dissolve the salt in a tank to form a concentrated brine solution.
2. Brine Proportioning
The saturated brine will be diluted into 2.5%-3%, the diluted brine can be adjusted and real-time monitored according to the value conductivity meter
3. Brine electrolysis
The diluted brine solution is passed through an electrolytic cell that, using DC current from a rectifier, electrolyzes the diluted brine into a 0.8% solution of sodium hypochlorite
4. Sodium hypochlorite solution storage
The final product 5000-7000 ppm (adjustable) of sodium hypochlorite solution will be kept in the storage tank and the hydrogen will be blown out to the air
5. Dosing
The sodium hypochlorite solution will be delivered into the water by dosing pump and the dosing rate of dosing pump can be adjusted by the feedback data of residual chlorine meter and PLC
Compared with other disinfection methods
| On-site prepared NaClO | The safest chemical disinfection method, environmental non-toxic, liquid dosing, on site and on demand |
| Liquid chlorine | Chlorine is toxic and corrosive. Chlorine transport and storage are unsafe, easily cause leaks and explosions, harm to human life and the environment |
| Commercial NaClO | Dangerous goods, unsafe to transport and storage, When stored easily degradable and the storage time is short. High transport costs, the liquid dosing |
| Chlorine Dioxide | Compound type reaction was not complete, dosing by-product exceeded; high purity type operating costs, are not suitable for medium-sized water plant |
