    The direct filtration water treatment scheme does not include sedimentation and in some cases flocculation. Compared to conventional treatment, direct filtration has lowered capital costs, reduced space requirements, decreased sludge quantities, and reduced coagulant dosages. One objective of this research was the statistical comparison of the direct filtration, Utah Valley Water Purification

    Direct filtration is a used for the treatment of good quality water supplies. It involves the addition of coagulant, rapid mix, flocculation and filtration. The major difference relative to conventional treatment is the absence of a separation process, such as sedimentation or flotation, between coagulant addition and filtration.
