filtration is a unit operation that is commonly used both in laboratory and production conditions. this apparatus adapted for laboratory work is often used to isolate the product of synthesis of a reaction when the product is a solid in suspension. the product of synthesis is then recovered faster and the solid is drier than in the of a simple filtration.

have any turbidity higher than 10-15 nephelometric turbidity units (ntus). 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.
filtration is a process that removes particles from suspension in water. removal takes place by a number of mechanisms that include straining flocculation sedimentation and surface capture. filters can be categorised by the main method of capture i.e. exclusion of particles at the surface of the filter media i.e. straining or deposition within the media i.e. in-depth
