Generation of sodium hypochlorite can be accomplished using electrolyzer systems. In these systems, crystallized salt is dissolved and used for electrolysis On-site.
Product Description
This on-site sodium hypochlorite generation systems are for freshwater, wastewater and seawater applications without chemical.Generation of sodium hypochlorite can be accomplished using electrolyzer systems. In these systems, crystallized salt is dissolved and used for electrolysis On-site.The electrolysis cells are designed for low brine feed flow rates, narrow electrode gaps, and produce sodium hypochlorite concentrations approaching one percent-A new choice of disinfection machine.
Technology Comparison
Sodium Hypochlorite Generators generally configured with the following components:
1) Electrolysis cells which is the Core components of the systems. Electrolyzes the 2-5% brine solution to produce sodium hypochlorite disinfection solution.
2) Salt dissolver: Provides the required salt solution for electrolysis.
3) PLC Control System: Directly monitor the safe and reliable operation of the entire generator system and the status of self-detection, alarm and self-stop in case of malfunction.
4) Power supply: DC power rectifier, Using professionally produced constant voltage and constant current power supply, Electric conversion efficiency> 92%, Low calorific value and stable operation, Electrolysis efficiency reaches 89-90%, saving energy consumption.
5) Storage tanks: One-piece molding without welding seam, It has good resistance to acid and alkali corrosion.
6) Dosing pumps with dosing controls: Provides the needed disinfection dose based upon the chlorine residual or flow rate of a receiving stream.

System Flow:
① Influent water passes through a water softener to reduce hardness therefore reducing the scaling of electrodes and lengthening the cleaning time
② Salt is dissolved by softened water into saturated brine in the tank.
③ The saturated brine will be diluted into 2.5%-3%, then pass through the electrolytic cell and finally be electrolyzed into 0.8-1% solution of sodium hypochlorite.
④ The 0.8-1% hypochlorite solution flows into a storage tank. Hydrogen that is the only byproduct of the process, is safely vented to the atmosphere.
⑤ The residual chlorine detector will monitor residual chlorine and return feedback to the PLC center. According to preset standards, the PLC Center will adjust the speed of the dosing pump.
