How sodium hypochlorite (NaOCL) makes in some Countries?

Some small treatment plants in Africa produce their own sodium hypochlorite on site from the electrolysis of brine. Power demands range from 1.7 to 4 kwh per lb. of NaOCL. 2 to 3.5 lbs. of salt are needed for each pound of NaOCL.

These units are fairly simple and are made in both the U.S. and the U.K.

What is Chlorine Disinfection?

CHLORINE DISINFECTION

Chlorine deactivates microorganisms through several mechanisms that can destroy most biological contaminants, including:

• Damaging the cell wall 
• Altering the permeability of the cell (the ability to pass water in and out through the cell wall) • Altering the cell protoplasm
• Inhibiting the enzyme activity of the cell so it is unable to use its food to produce energy
