NOVEL LOW-ENERGY WATER TREATMENT SYSTEM COMBINING USE OF SEWAGE MATERIAL AND SEAWATER DESALINATION TECHNIQUE

摘要

The present invention relates to a water treatment system, and more specifically, to a water treatment system which comprises a forward osmosis device, a reverse osmosis device, and a rear-end membrane separation tank, and is capable of using sewage materials and desalinating seawater simultaneously. In particular, provided is a water treatment system comprising: a floatation separation tank (100) which receives raw water; a first forward osmosis device (200) which receives the raw water treated in the floatation separation tank (100), wherein the first forward osmosis device (200) further receives an induction solution, seawater; a reverse osmosis device (300) which receives the seawater diluted in the first forward osmosis device (200); a second forward osmosis device (400) which receives concentrated seawater left after being treated in the reverse osmosis device (300) and receives the raw water concentrated in the first forward osmosis device (200); and a membrane separation tank (500) which receives and treats sewage further concentrated in the second forward osmosis device (400), wherein the seawater diluted in the second forward osmosis device (400) is discharged to the outside.;COPYRIGHT KIPO 2018
