Hiki ke hoʻokaʻawale ʻia ka ʻenehana hoʻomaʻemaʻe wai ʻoihana i ʻekolu mau ʻāpana e pili ana i nā pahuhopu lapaʻau a me ka maikaʻi o ka wai: kino, kemika, a me ka biological. Hoʻohana nui ʻia ia i ka mālama ʻana i nā ʻano ʻano like ʻole o ka wai ʻino ʻoihana.
1. ʻenehana hana kino: ʻo ka nui me ka kānana, ka ua, ka lele ʻana o ka ea, a me ka ʻenehana hoʻokaʻawale membrane. Hoʻohana mau ʻia ka kānana no ka wehe ʻana i nā mea i hoʻopaʻa ʻia mai ka wai; Hoʻohana ʻia nā ʻenehana sedimentation a me ka lele ʻana o ka ea e hoʻokaʻawale i ka ʻaila a me nā ʻāpana paʻa; Hoʻohana ʻia nā ʻenehana hoʻokaʻawale membrane, e like me ka ultrafiltration a me ka reverse osmosis, no ka hoʻomaʻemaʻe kiʻekiʻe a kūpono no ka mālama ʻana i ka wai paʻakai kiʻekiʻe a me ka hoʻihoʻi ʻana i nā mea pono.
2. ʻenehana lapaʻau kemika: Wehe i nā mea haumia ma o nā hopena kemika, me nā ʻano e like me ka flocculation, oxidation-reduction, disinfection, a me ka neutralization. Hoʻohana mau ʻia ka Flocculation a me ka coagulation e wehe i nā ʻāpana maikaʻi; Hiki ke hoʻohana ʻia ke ʻano hoʻohaʻahaʻa oxidation e hoʻohaʻahaʻa i nā mea haumia organik a i ʻole e wehe i nā metala kaumaha; Hoʻohana nui ʻia nā ʻenehana disinfection e like me ka chlorination a i ʻole ka lāʻau ozone no ka hoʻohana hou ʻana i ka wai ʻoihana a i ʻole ka mālama ʻana ma mua o ka hoʻokuʻu ʻana.
3. ʻenehana lapaʻau olaola: e hilinaʻi ana i nā microorganism e hoʻohaʻahaʻa i nā mea ola i loko o ka wai, ʻo nā ʻenehana maʻamau e pili ana i ke kaʻina sludge hoʻōla a me ke kaʻina hana anaerobic. He kūpono ke kaʻina hana ʻōpala i hoʻohana ʻia no ka mālama ʻana i ka wai ʻino me ka haʻahaʻa organik kiʻekiʻe, ʻoiai ʻo ka ʻenehana lapaʻau anaerobic e hoʻohana mau ʻia no ka mālama ʻana i ka wai ʻōpala kūlohelohe kiʻekiʻe, hiki ke hoʻohaʻahaʻa i nā mea haumia a hoʻihoʻi hou i ka ikehu (e like me ka biogas).
Hoʻohana nui ʻia kēia mau ʻenehana i ka mālama ʻana i ka wai ʻino i nā ʻoihana e like me ka petroleum, kemika, ka meaʻai, a me nā lāʻau lapaʻau. ʻAʻole lākou e hōʻemi wale i ka pollution wai, akā hoʻomaikaʻi pū i ka hoʻohana hou ʻana o ka wai, e hāpai ana i ka hoʻomohala mau ʻana o ka hana ʻoihana.
