Abstract
The purpose of filtration is to remove the particulates suspended in water by passing the water through a layer of porous material. Larger particulates are retained by straining and sedimentation, while colloidal matter is retained by adsorption, or coagulation and sedimentation. Biological interactions occur only when the water passes very slowly through the porous mass.
