How long should you maintain the concentration of chlorine at 20mg/L during hyper-chlorination?

Maintaining a concentration of chlorine at 20 mg/L during hyper-chlorination is essential for effectively disinfecting water systems. The recommended duration of 24 hours allows sufficient time for the chlorine to react with any pathogens, organic materials, and biofilms present in the system.

During this period, the chlorine works to kill bacteria, viruses, and other microorganisms that may be present in the water. A full 24-hour exposure is particularly important for ensuring that the chlorine achieves its maximum disinfection potential throughout the entire system, including areas that may have been otherwise difficult to reach or flush out.

Additionally, holding the chlorine at this concentration for 24 hours helps ensure that even residual contaminants are managed effectively. If the time were shorter, there may be insufficient exposure for effective disinfection, which could leave harmful pathogens in the water supply, potentially posing health risks. Conversely, extending the chlorine exposure significantly beyond 24 hours could lead to damage to the infrastructure due to corrosion or the formation of harmful byproducts.

This balance of efficacy and safety underscores the importance of the 24-hour maintenance period in hyper-chlorination practices.
