3 kg / h Active Chlorine NaClO Solution Make by Electrolysis from S alt Water

Brief Introduction

It is a proven technology to convert sea water, by means of electrolysis into sodium hypochlorite (ELECTRO HYPO) using GEEMBLUE sodium hypochlorite generators (electro chlorination system). It is applied onsite, No chemicals other than sea water are used throughout the process.

The electrolytic cell is fed a DC current from the rectifier and electrolyzes the seawater into sodium hypochlorite solution. Chlorine evolves at the anode surface, while hydrogen and hydroxide evolves at the cathode surface. The secondary reaction of chlorine, sodium and the hydroxyl ion nets sodium hypochlorite (chlorine bleach) at a 0.2% solution. The only by-product, hydrogen, is safely vented into the atmosphere.

Process

1. Influent water is passed through a water softener.

2. Using softened water to dissolve the salt in a tank to form a concentrated brine solution.

3. Diluted into 2.5%-3% after filtered (If use sea water as raw material, it will be treated before electrolysis)

3. The diluted brine is electrolyzed to a 0.8% solution of sodium hypochlorite.

4. The 0.8% hypochlorite solution flows into a storage tank.
5. The sodium hypochlorite solution will be injected into the pipe by metering pump.

6. The residual chlorine detector will monitor residual chlorine and return feedback to the PLC center.

7. According to preset standards, the PLC Center will adjust the speed of the dosing pump.

Benefit of Geemblue EC system

High Safety Level

Food grade standard solution, multi-protection for each components, multi-protection for hydrogen exhaust

Low Running Cost

To produce 1 kg available chlorine, only cost 3.5kg salt, 4kwh power

Full Automatic Operation

Full computer program and central control by PLC, the staff can operate after simple training

Accuracy Control Dosing

Closed loop control system, ensure accuracy residual chlorine in water and make use of every drop of solution

Product components
