Akwai manyan hanyoyi guda uku:
1. Hanyar sinadarai
A taƙaice, yana nufin ƙara abubuwan sinadarai a cikin ruwa mai datti don ƙyale dattin da ke ciki su amsa kuma su zama masu iya cirewa cikin sauƙi.
Hanyar coagulation:TYana aiki ka'idar hanyar coagulation shine ƙara abubuwan sinadarai a cikin ruwa, yana haifar da ƙananan barbashi da aka dakatar don tattarawa kuma su samar da manyan gungun, sa'an nan kuma daidaita su ta hanyar nauyi. Wannan hanya na iya cire chromaticity yadda ya kamata, kwayoyin cuta, da wasu kwayoyin halitta daga ruwa. Koyaya, tasirin maganin sa akan abubuwan da aka narkar da su gabaɗaya a cikin ruwa yana iyakance, kuma tasirin jiyya yana da sauƙin shafar canjin yanayin ruwa da ƙimar pH.
Hanyar Oxidation:Uraira oxidants (kamar chlorine, ozone) don lalata abubuwa masu guba zuwa marasa lahani. Ozone yana da sakamako mai kyau kuma babu gurɓataccen gurɓataccen abu, amma farashin yana da yawa; Ana amfani da Chlorine da yawa kuma ya dace don magance ruwan sha mai ɗauke da phenol da cyanide; Tasirin iskar iskar shaka yana da dan kadan mara kyau kuma ana amfani dashi gabaɗaya a cikin ruwan sharar gida inda ake samun gurɓataccen abu cikin sauƙi.
Hanyar sinadarai: Ana amfani da wutar lantarki don ƙyale gurɓata yanayi su mayar da martani akan saman lantarki don cirewa, kuma wani lokacin ana ƙara sodium chloride don haɓaka tasirin. Wannan hanya tana da tasiri mai kyau na sarrafawa, amma kuma rashin amfaninta a bayyane yake: a gefe guda, tana cinye wutar lantarki da yawa kuma yana da tsadar aiki; A gefe guda kuma, wasu halayen gefe na iya faruwa yayin aikin, wanda zai haifar da gurɓataccen gurɓataccen abu.
2. Hanyar Jiki
Ware ƙazanta masu ƙarfi daga ruwa ta hanyoyin jiki.
Hanyar tacewa tana amfani da kafofin watsa labarai masu tacewa tare da micropores (kamar matattarar microporous) don tsinkayar daskararrun daskararru a cikin ruwa.
Ka'idar lalatawa ita ce a yi amfani da nauyi don ba da damar barbashi da aka dakatar da su a cikin najasa su zauna a ƙasan ruwa ta zahiri.
Hanyar yawowar iska tana gabatar da adadi mai yawa na ƙananan kumfa a cikin ruwa, yana sa su manne da ɓangarorin ƙazanta kuma su samar da jiki mai iyo tare da ƙarancin ƙarancin ruwa. Sa'an nan kuma ya tashi zuwa saman ruwa ta hanyar buoyancy kuma an cire shi ta hanyar gogewa.
Waɗannan hanyoyin suna da sauƙi kuma suna da sauƙin sarrafawa, amma ba za su iya cire gurɓataccen gurɓataccen ruwa da aka narkar da su cikin ruwa ba kuma suna da gazawa wajen amfani da su.
3. Photocatalytic oxidation fasaha
Ta hanyar amfani da hasken ultraviolet da abubuwan da ke haifar da iskar oxygen (kamar hydrogen peroxide), da wuya a lalata gurɓataccen gurɓataccen abu (kamar polychlorinated biphenyls) na iya lalata su gaba ɗaya.
Akwai hanyar da ake kira 'photocatalytic Fenton', wanda zai iya hanzarta samar da adadi mai yawa na abubuwa masu aiki da kuma lalata kwayoyin halitta da kyau a ƙarƙashin aikin haɗin haske da ions baƙin ƙarfe.
Wata hanya kuma ita ce ƙara kayan aikin semiconductor masu ɗaukar hoto (kamar titanium dioxide), waɗanda ke haifar da radicals masu ƙyalƙyali a ƙarƙashin iskar haske, gaba ɗaya suna lalata gurɓataccen gurɓataccen abu zuwa abubuwa marasa lahani kamar carbon dioxide da ruwa. Wannan hanya tana da babban yuwuwar magance gurɓataccen gurɓataccen abu.
