What method is used to disinfect water systems after flushing?

Chlorination is a widely accepted method for disinfecting water systems after flushing due to its effectiveness in killing bacteria, viruses, and other pathogens that may be present. This process involves adding chlorine, or chlorine compounds, to the water, which serves as a powerful disinfectant. Chlorine reacts with organic materials and microorganisms, ensuring that residual chlorine remains in the system to provide ongoing disinfection, especially in larger systems where water might stagnate.

This method is particularly advantageous because it not only removes harmful pathogens but also can be adjusted to achieve the desired residual levels in the water supply. Additionally, chlorination is cost-effective and easy to implement, making it suitable for a variety of water systems. Compared to other disinfection methods, like ozonation or ultraviolet treatment, chlorination provides a lasting residual effect, which is crucial in maintaining water quality over time.
