What is chlorination efficiency and how does turbidity affect chlorination efficiecy?
5 answers
Chlorination efficiency refers to the effectiveness of chlorination in improving water quality by reducing pathogens and impurities. Turbidity, caused by suspended particles, can impact chlorination efficacy. High turbidity levels can hinder chlorination by shielding pathogens from the disinfectant, reducing its effectiveness. Moreover, turbidity exceeding recommended levels can lead to disruptions in water treatment processes, affecting the quality of treated water. Studies have shown a correlation between increased raw water turbidity and decreased treatment efficiency, particularly affecting filtration processes. Evaluations have demonstrated that turbidity above permissible limits can make water undrinkable and reduce the disinfectants' ability to treat pathogens effectively.What are the current challenges in WAAM?
