He maha ngā momo whakarewa waikura, ka taea te wehewehe i ēnei ki ngā wāhanga e rua, ko tētahi he whakarewa waikura kore-waro, ko tētahi he whakarewa waikura waro.
(1) Ngā mea whakapūkara kore-waro: tae atu ki ngā momo tote whakarewa e rua, ngā tote rino me ngā tote konumohe, tae atu ki ngā mea whakapūkara polymer kore-waro pērā ipūhaumāota polyaluminiumKo ngā mea e whakamahia whānuitia ana ko: te konupūmā ferric, te konupūmā ferric, te konupūmā ferric, te konupūmā konumohe (konumohe), te konupūmā konumohe taketake, me ētahi atu.
(2) Ngā wai whakapūkara waro: ko te nuinga he matū pūmua pērā i te polyacrylamide. Nā te mea he pai ngā wai whakapūkara pūmua: he iti te horopeta, he tere te tere o te whakatō, he kaha te wai whakapūkara, me te kaha ki te whakanui ake i te tere tātari, he maha ki te tekau ngā wā ka nui ake tōna pānga wai whakapūkara i ērā o ngā wai whakapūkara kore-waro tuku iho, nō reira e whakamahia whānuitia ana i roto i ngā kaupapa maimoatanga wai i tēnei wā.

Te whakapūkara polymer--polyacrylamide
Ko te rauemi mata matua opolyacrylamide (PAM te whakarapopototanga)he acrylonitrile. Ka konatunatua ki te wai i tētahi ōwehenga, ā, ka whiwhi mā te whakamakuku, te purenga, te polymerization, te whakamaroke me ētahi atu tukanga.
Ko ngā whakatau e whai ake nei ka taea te tango mai i ngā whakamātautau o mua:
(1) He pai te PAM anionic mō ngā mea iri kore-waro me te kukū teitei me te utu pai, me ngā matūriki iri matotoru (0.01~1mm), me te uara pH kūpapa, kawakore rānei.
(2) He pai te PAM kationika mō ngā mea iri me te utu kino, ā, kei roto hoki ngā mea rauropi.
(3) He pai te PAM kore-ionic mō te wehewehe i ngā mea i whakatārewatia i roto i te āhua rauropi me te āhua kore-rauropi, ā, he waikawa, he koretake rānei te otinga.
Te whakarite i te flocculant
Ka taea te whakamahi i te wai whakapūkara hei wāhanga totoka, hei wāhanga wai kukū teitei rānei. Mēnā ka tāpirihia tika tēnei wai whakapūkara ki te whakatārewatanga, nā te mea he nui te kiato me te iti o te tere horapa, kāore e taea te hora pai o te wai whakapūkara i roto i te whakatārewatanga, ā, ka kore e taea e tētahi wāhanga o te wai whakapūkara te mahi whakapūkara, ka moumou te wai whakapūkara. Nō reira, me whakamahi he mīhini whakaranu whakarewa hei whakaoho i te wai whakapūkara me te nui o te wai e tika ana kia tae atu ki tētahi kukū, ko te tikanga kāore e neke atu i te 4~5g/L, ā, i ētahi wā he iti iho i tēnei uara. I muri i te whakaoho ōrite, ka taea te whakamahi. Ko te wā whakaoho he tata ki te 1~2h.
I muri i te whakaritenga o te polymer flocculant, ko tōna wā whai mana he 2~3 rā. Ina huri te wairewa hei mā, ko te tikanga kua pakaru te wairewa, kua pau te wā, ā, me mutu tonu te whakamahi.
Ka taea e te rōpū amide o te polyacrylamide i hangaia e Yixing Cleanwater Chemicals Co., Ltd. te hono atu ki ngā matū maha, te mimiti me te hanga hononga hauwai. Ko te polyacrylamide taumaha ngota teitei te hanga hononga i waenga i ngā katote mimiti, te whakaputa i ngā flocs, me te whakatere i te whakatō o ngā matūriki, kia tutuki ai te whāinga matua o te wehenga totoka-wai. He momo anionic, cationic me te kore-ionic. I taua wā anō, ka taea hoki e ngā kiritaki te whakarite i ngā hua o ngā whakaritenga rerekē.
