What does Shock Chlorination involve?

Shock chlorination specifically refers to the practice of adding a high dose of chlorine to a water supply system to disinfect it. This process is particularly effective for removing harmful bacteria, viruses, and other pathogens that may be present in the system. During shock chlorination, chlorine is applied at levels significantly above those typically used for routine disinfection, allowing for a more thorough sanitization of pipes, tanks, and other components of the water distribution system.

The purpose of shock chlorination is primarily to eliminate biological contaminants, making it crucial for restoring safe water quality after contamination events or during the commissioning of a new water system. This method is commonly employed when a system is first put into service or if there is evidence of microbial contamination, ensuring the safety and health of the water for consumers.
