WATER TREATMENT DEVICE AND METHOD |
摘要 |
A water treatment device (100) comprises: a membrane desalination unit (102); a first conduit (104) transporting a first stream of feed water (106) to the membrane desalination unit; a second conduit (108) transporting a first stream of product water (110) of lower salinity than the first stream of feed water out of the membrane desalination unit; an electrical separation unit (112); a third conduit (114) transporting a first stream of reject water (116) of higher salinity than the first stream of feed water from the membrane desalination unit to the electrical separation unit; a fourth conduit (118) transporting a second stream of product water (120) of lower salinity than the first stream of reject water out from the electrical separation unit; a precipitation unit (122); a fifth conduit (124) transporting a second stream of reject water (126) of higher salinity than the first stream of reject water from the electrical separation unit to the precipitation unit; a sixth conduit (128) transporting a second stream of feed water (130) of lower salinity than the second stream of reject water from the precipitation unit to the electrical separation device; a seventh conduit (132) releasing a discharge stream of water (134); and a chemical injection unit (136) in communication with at least one of the electrical separation device and the precipitation unit. Associated method is also provided.
