This is the second part of a 2-part series on minimizing the initial turbidity spike after filter backwash. This part focuses on adding coagulant chemical or cationic polymer to the settled water as it fills the filter box after backwash is terminated. Experiences from four different treatment plants with adding coagulant chemical or cationic polymer are compared. A list of important data to collect, record, and evaluate when studying the addition of conditioning chemicals to backwash water is provided. |
