MEMBRANE FILTRATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To suppress clogging of a membrane by separating or collecting granular activated carbon or the like in the previous stage of a membrane filtration apparatus in the system to remove and adsorb soluble components and a trace amount of deleterious substances. SOLUTION: A membrane filtration system includes: a raw water receiving well 2 in which a raw water taken from the water source is stored; an activated carbon addition unit 8 for supplying an activated carbon to the raw water receiving well; a solid-liquid separation apparatus 3 for separating the activated carbon to be processed in the raw water from the water; a flocculating agent addition unit 9 for supplying a flocculating agent; a floc forming pond 5 for forming a floc; and a membrane filtration apparatus 6 for separating undissolved components to the water. The system is characterized by installing the solid-liquid separation apparatus in the latter stage of the raw water receiving well in the system. COPYRIGHT: (C)2011,JPO&INPIT
