Filter Media Selection Criteria - Wastewater Treatment
Filter Media Selection Criteria - Wastewater Treatment

Filter media selection should be guided by the following rule: a, filter medium, must incorporate a, maximum size of pores, while at the same time providing a sufficiently pure filtrate. Fulfilment of this rule invokes difficulties because the increase or decrease in pore size acts in opposite ways on the filtration rate and solids retention capacity. The difficulty becomes accentuated by several other requirements …
