Detailed Solution

Chlorination is a common method for reducing the number of harmful pathogens in domestic sewage.

Chlorination is often used in wastewater treatment plants to disinfect sewage before it is discharged into the environment or reused for irrigation or other purposes. It is also used to disinfect drinking water supplies to protect public health.

The process involves adding a measured amount of chlorine to the water, which reacts with the organic matter in the water to form highly reactive compounds that kill pathogens. This helps to reduce the risk of the spread of waterborne diseases and improve the overall quality of the treated water.
