In water treatment plant operation does over dosing on filter aid chemicals prevent sealing of filter media?
1. Polymers used as filter aids are similar to flocculants in both structure and function.
2. Filter aid polymers are typically fed at dosages less than 0.1 mg/L; when fed in higher concentrations, they can contribute to filter head loss and short filter run times.
3. Filter aid polymers are fed at a point of gentle mixing (e.g., filter influent trough).
4. Product density and solution strength information can be obtained from the individual polymer manufacturers
