Amanzi angcolile anosawoti omningi asho amanzi angcolile aqukethe izinto eziphilayo kanye nokungenani u-3.5% (i-mass concentration) inani elincibilikisiwe eliphelele (TDS). Lolu hlobo lwamanzi angcolile luvela emithonjeni ehlukahlukene. Okokuqala, kumakhemikhali, imithi, i-petroleum, ukwenza iphepha, ukucubungula umkhiqizo wobisi, ukucwiliswa kokudla kanye nezinye izinqubo zokukhiqiza izimboni, amanzi amaningi angcolile azokhishwa. Amanzi awagcini nje ngokuqukatha izinto eziningi ezingcolisayo eziphilayo, kodwa futhi Ahambisana nenani elikhulu le-calcium, i-sodium, i-chlorine, i-sulfate namanye ama-ion; okwesibili, ukuze kusetshenziswe ngokugcwele imithombo yamanzi, amadolobha amaningi asogwini asebenzisa ngokuqondile amanzi olwandle njengamanzi okukhiqiza ezimbonini noma amanzi okupholisa, kanti ezinye izindawo zisebenzisa amanzi olwandle ukulwa nomlilo, izindlu zangasese ezishaywayo kanye nemigwaqo, Nakuba le ngxenye yendle ingenayo inani elikhulu lezinto ezinobuthi, kunzima ukuyelapha ngenxa yomthamo wamanzi amaningi kanye nosawoti omningi. Izinto eziphilayo zamanzi angcolile anosawoti omningi ziyahlukahluka ohlotsheni namakhemikhali ezinto eziphilayo ngokuya ngenqubo yokukhiqiza, kodwa usawoti oqukethwe kakhulu yi-Cl-, SO42-, Na+, Ca2+ kanye namanye ama-salts. Nakuba lezi ion ziyizakhi ezibalulekile ekukhuleni kwama-microorganisms, zidlala indima ebalulekile ekukhuthazeni ukusabela kwe-enzyme, ukugcina ibhalansi ye-membrane kanye nokulawula ingcindezi ye-osmotic ngesikhathi sokukhula kwama-microorganisms, kodwa uma ukugxila kwalawa ma-ion kuphezulu kakhulu, kuzovimbela futhi vimbela ama-microorganisms. Umphumela onobuthi. Ukuhlushwa kukasawoti omningi, ukucindezela okuphezulu kwe-osmotic, nokuphelelwa amandla kwamanzi kwamangqamuzana e-microbial emanzini angcolile anosawoti omningi kubangela ukuhlukana kwe-cell protoplasm; imvula kasawoti inciphisa umsebenzi we-dehydrogenase; i-chloride ion ephezulu inobuthi kubhaktheriya; Udaka kulula ukuntanta futhi lubaleke, ngaleyo ndlela kube nomthelela omkhulu ekuhlanzeni kohlelo lokwelapha lwebhayoloji.
Amanzi angcolile anosawoti omningi ane-conductivity ephezulu kagesi, ngakho-ke angakwazi ukukhiqiza amandla akhona phakathi kwamazinga e-yin ne-yang nge-electrolysis ukuze abangele ukusabela kwe-redox kwezinto ezinobuthi neziyingozi ukuze kususwe ukungcola emanzini. I-Electrolysis inganciphisa ngempumelelo i-COD emanzini angcolile. , Ikwazi ukuguquguquka okunamandla kumfucumfucu kanye nomphumela omuhle wokususwa, kodwa okubi ukuthi izindleko zokusebenza ziphezulu. Indlela ye-electrolytic flocculation isetshenziselwa ukwelapha amanzi angcolile aphezulu anosawoti omningi akhishwa kunqubo yokukhiqiza i-shellac synthetic resin, engakwazi nje ukunciphisa ngempumelelo i-COD emanzini angcolile, ikhulise ukukhanya, kodwa futhi ibe nezinga eliphezulu lokususwa kwe-BOD, TP kanye TN.
Isihluthulelo sendlela yokushintshanisa ye- cationic polyacrylamide sise-ion exchange resin, okuyi-polymer ephezulu yamangqamuzana enamaqembu asebenzayo, ukwakheka kwenethiwekhi nokungancibiliki. Ama-ion ensimbi kuwo acwecwa futhi ashintshwe. Indlela yokushintshanisa i-ion ingasetshenziswa njengenqubo yokwelashwa ngaphambi kokukhipha ama-ion ensimbi ahlukahlukene futhi kuzuzwe inhloso yokukhipha usawoti emanzini. Ububi bayo ukuthi into eqinile emisiwe emanzini angcolile izovimba inhlaka futhi yenze i-cationic polyacrylamide exchange resin ingasebenzi. Tang Shuhe et al. kusetshenziswe i-ion exchange resin ukwelapha amanzi angcolile aqukethe i-Cr, futhi ukugcwala kwe-Cr emanzini angcolile kwehle kusuka ku-1540 mg/L ekuqaleni kuya ku-0.5 mg/L ngemva kokwelashwa, okuhlangabezana nezinga likazwelonke lokukhipha.
