Ngokukhula koshishino, iikhemikhali, amayeza, ukuprinta kunye nokudaya, ukwenza amaphepha kunye namanye amashishini aphuhliswa ngokuqhubekayo. Nangona kunjalo, inani elikhulu leekhemikhali kunye nezinto ezibonakalayo zisetyenziselwa inkqubo yokuvelisa la mashishini, kwaye ezi zinto zinokusabela ngamanzi ngexesha lenkqubo yokuvelisa ukwenza amanzi amdaka aqulethe ukuxinwa okuphezulu kwezinto ezingcolileyo. Ngenxa yokuxinana okuphezulu kongcoliseko kumanzi amdaka agxininiswe kakhulu, iindlela zonyango zemveli zihlala zinzima ukuzisusa ngokufanelekileyo, ngoko ke izixhobo ezikhethekileyo zokucocwa kwamanzi amdaka ziyafuneka.
Ukunyangwa kwamanzi amdaka agxininiswe kakhulu kubaluleke kakhulu kuba olu hlobo lwamanzi amdaka luqulethe inani elikhulu lezinto ezinobuthi kunye neziyingozi, eziya kubangela ingozi enkulu kwimeko yendalo ukuba ikhutshwe ngokuthe ngqo kwimo engqongileyo. Ukongeza, amanzi amdaka agxininise kakhulu anokuba yingozi kwimpilo yabantu kwaye anokubangela izifo ezahlukeneyo.
Iindlela zonyango lomzimba ziquka ubuchule obufana ne-sedimentation, filtration kunye nokwahlulwa kwe-centrifugal yokususa amasuntswana amisiweyo kunye aqinileyo kumanzi amdaka. Ngakolunye uhlangothi, iindlela zonyango zonyango zisebenzisa iikhemikhali ukuze zinciphise okanye zisuse izinto ezinobungozi kumanzi amdaka, njenge-acid-base neutralization kunye nokunciphisa i-oxidation. Iindlela zonyango lwebhayoloji zisebenzisa i-metabolism ye-microorganisms ukubola izinto eziphilayo zibe zizinto ezingenabungozi.
Ukusetyenziswa koxinzelelo oluphezulu lwezixhobo zokucocwa kwamanzi amdaka akuncedi kuphela ukukhusela indalo, kodwa kugcina iindleko kumashishini. Ngonyango olusebenzayo lwamanzi amdaka, inokunciphisa imirhumo yogutyulo lweshishini, kwaye kwangaxeshanye, ibuyise kwakhona imithombo eluncedo kumanzi amdaka kwaye iphucule izinga lokusetyenziswa kwemithombo.
Ngamafutshane, izixhobo zokucocwa kwamanzi amdaka zoxinzelelo olukhulu zibaluleke kakhulu ekukhuseleni okusingqongileyo kunye nokukhuthaza uphuhliso oluzinzileyo. Ngokuphuculwa okuqhubekayo kolwazi lokhuseleko lokusingqongileyo, olu hlobo lwezixhobo luya kusetyenziswa ngokubanzi kwiindawo ezininzi.
