How does chlorination system work?

Chlorine inactivates a microorganism by damaging its cell membrane. Once the cell membrane is weakened, the chlorine can enter the cell and disrupt cell respiration and DNA activity (two processes that are necessary for cell survival).

How is chlorine used in drinking water?

Drinking water chlorination is the addition of chlorine to drinking water systems. It is the most common type of drinking water disinfection. Disinfection kills bacteria, viruses, and other microorganisms that cause disease and immediate illness.

What are the methods of chlorination?

The different types of chlorine disinfection are batch disinfection, simple chlorination, super-chlorination followed by dechlorination, and shock chlorination. They vary in the amount of chlorine used.

How is water purification done?

There are several methods used in the water purification process, which include: (1) physical processes, such as filtration, sedimentation, or distillation; (2) biological processes, such as sand filters, active carbon; (3) chemical processes, such as flocculation, chlorination, the use of ultraviolet light.

What is chlorination explain the various stages of chlorination?

Chlorination is the application of chlorine to the water for the purpose of disinfection. During pre-chlorination, chlorine is usually added to raw water after screening and before flash mixing. Post-chlorination, in contrast, is often the last stage in the treatment process.

How long does chlorine last in tap water?

2 ppm of Chlorine will take up to 4 and a half days or around 110 hours to evaporate from 10 gallons of standing water. Ultraviolet light, water circulation, and aeration will speed up the evaporation process dramatically. Chlorine will last between 6 and 8 minutes in 10 gallons of boiling tap water.

Why pre chlorination is done?

Prechlorination is a process that involves adding chlorine to the collection system of industrial plants and other industrial settings, mainly for corrosion and odor control. At times, it is also applied for the purpose of disinfection and for the removal of oil particles.
