FILTERING APPARATUS CAPABLE OF IMPROVING THE EFFICIENCY OF A FILTERING PROCESS AND THE EFFICIENCY OF A BACK WASHING PROCESS

摘要

PURPOSE: A filtering apparatus is provided to facilitate the attaching operation or the separating operation of tubular units in a filtering/back washing operation by using telescopic type tubular units.;CONSTITUTION: A filtering apparatus includes a tubular filter(130). Raw water is introduced through a raw water inlet(112), and filtered water is discharged through a filtered water outlet(116) in a filtering process. Washing water backwardly flows in a back washing process. The filter includes a plurality of tubular units(135). The tubular units are telescopically combined to be attached. A plurality of grooves is longitudinally arranged to either the inner circumferences or the outer circumferences of the tubular units. Filtering flow paths are arranged between the tubular units.;COPYRIGHT KIPO 2012
