WATER CATCHMENT DEVICE FOR MULTIPLEX FILTRATION

摘要

PURPOSE: Multiple filtering general collectors are provided to have a simple general structure, perform the filtering and collecting function of water at the same time, improve the functionality and usability, and more improve the filtration efficiency. CONSTITUTION: Multiple filtering general collectors comprise a casing; an inner partition (20) of the barrel; a water permeability wall (30); a perforated panel (40); the first filter media (50) filled between the permeability wall and the perforated panel; the second filter media (60) filled between the casing and the inner partition. A raw water inlet port is formed in the casing. An inside partition is installed inside the casing and a filtered water inlet port is formed. A permeability wall is installed between the casing and the inner partition and forms a raw water accommodating space (S) which is connected to the raw water inlet port. A perforated panel is installed on the outside of the permeability wall based on the direction which raw water flows in through the raw water inlet port. The casing comprises a cylindrical body (12) and a top cover which is installed to divide the top portion of the body. A top portion having a raw water inlet port is formed to be open in the body. An opening and closing door is equipped on the top cover.
