The primary differences between conventional, direct, and in-line filtration processes lie in the sequence and types of pre-treatment steps used before filtration. All three processes use filtration to remove suspended solids and particulate matter from water, but they differ in how the water is prepared for filtration. Conventional filtration typically involves a complete series of pre-treatment steps, including coagulation, flocculation, and sedimentation, before the water is applied to the filters. Coagulation involves adding chemicals to destabilize the suspended particles, flocculation involves gentle mixing to....
