Small Brine Electrolysis Sodium Hypochlorite Generator For Water Treatment
Product introduce:
Sodium hypochlorite generator is a generator to produce sodium hypochlorite by brine or sea water electrolysis, and the whole system is a combination of softener, salt dissolving unit, brine proportion unit, control system, electrolytic unit, storage unit, dosing unit and acid washing unit. It's a system using salt as raw material to produce sodium hypochlorite liquid (0.8%) and dose into water for disinfection.
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↑
Product components

Comparison between chlorine gas and electro chlorination system (EC system)
| Analysis | Chlorine gas | EC system | |
| Raw materials | Industrial salt | Salt + water or sea water | |
| Easy to buy | Easy to buy | ||
| Storage and dosing | Storage | Pressure cylinder | PE plastic tank |
| Dosing equipment | Vacuum chlorine dosing machine | Pump | |
| Dosing accuracy | low hydrolysis rate, inaccurate dosing | high accurate | |
| Status | Chlorine concentration | 95% | 0.5-0.8% |
| Status | strong irritant gas, a highly toxic, explosive and leakage risk | Stable low concentration liquid | |
| Disinfection Byproducts | easily exceeded of Chlorate or chlorite, leading to contamination of the water quality | Highly safe disinfectant | |
| Smell on water | Strong chlorine smell | No smell | |
| Cautions | Leakage prevention measures | Must be strictly set chlorine leak absorption device | No special protective measures water to flush and dilute when leakage. |
| Leak harmful levels | Gaseous state, once the leak is easy to large-scale diffusion, causing serious social harm consequences | Liquid with low concentration, easy dilute and flush into the sewage pipes. | |
| Maintenance | Operation and Maintenance | Professional training course | No special requirements |
| Equipment costs | Medium | High | |
| Operation and maintenance costs | Medium | Low | |
