Document Type and Number:
Japanese Patent JP6447098
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a recovery filtration unit capable of re-utilizing treated water in existing waste-water treatment facility more efficiently.SOLUTION: A recovery filtration unit comprises: a filtration membrane apparatus which performs membrane filtration to primary treated water recovered from waste-water treatment facility by a filtration membrane module to obtain secondary treated water; and a reverse osmosis membrane apparatus which performs membrane separation to the secondary treated water from the filtration membrane apparatus by a reverse osmosis membrane module to obtain permeated water as third treated water, in which the permeated water as the third treated water obtained in the reverse osmosis membrane apparatus is supplied as manufacturing water, concentrated water as the third treated water obtained by the reverse osmosis membrane apparatus is supplied as backwashing water of a filter material in a filtration apparatus installed to a treatment system outside the unit, and the secondary treated water obtained in the filtration membrane apparatus is supplied as rinsing water of the filter material after backwashing.SELECTED DRAWING: Figure 1
