At Water Hygiene Solutions We've got competent workers who can advise on your water chlorination requirements, like which disinfecting agent it is best to use and what dosing concentration and frequency is required.

Chlorine gasoline may be received like a fluid gas and is highly water soluble, consequently its reputation. Only small concentrations are needed to destroy microorganisms, and actually chlorine alone is just used for giant municipal swimming pools and huge water storage or re-circulation tanks. For tiny applications you can use sodium hypochlorite as a substitute.

Chlorine inactivates a microorganism by detrimental its cell membrane. As soon as the cell membrane is weakened, the chlorine can enter the cell and disrupt mobile respiration and DNA activity (two processes that are needed for mobile survival).
