2021-7-14  In direct filtration, no clarification follows the coagulation phase. Direct filtration is designed to filter water with an average turbidity of less than 25 NTU. Dual and multi-media filters are used with direct filtration. They are able to remove more suspended material per cubic foot of filter media than sand filters.

Granular Medium Filtration - an overview ScienceDirect ...

Granular media filtration (GMF) is a process for removing suspended or colloidal particles; for example removing suspended solids remaining after sedimentation clarification. It reduces turbidity and improves clarity by removing various sized particles, from coarse sediment down to 10.0 μm [ 10, 12 ].
