I roto i te tukanga maimoatanga waipara, me whai i tētahi raupapa mahi, ā, i muri i te whakamātautau kia tutuki ai te paerewa tukunga, ka tukuna atu. I roto i tēnei raupapa tukanga, he mahi nui tā te flocculant. Ko teKaiwhakarewa waika taea te whakapūpū i ngā mea iri o ngā ngota iti i roto i te wai. Ka tau, ka māmā te tātari. He tino momona hoki ngā momo whakapūpū. He mea nui hoki te whiriwhiri i te whakapūpū e pai ana ki a koe. Mō te whiriwhiri i ngā whakapūpū, ko ngā kaihanga PAM me PAC ēnei e whai ake nei:
Me whiriwhiri te huarahi ki te whiriwhiri i tētahi waipara i roto i te maimoatanga waipara kia rite ki ngā āhuatanga o te waipara i roto i tētahi umanga motuhake. I taua wā anō, ka whakawhirinaki hoki ki te wāhi e tāpirihia ai te waipara me te aha e whakamahia ai. I te nuinga o te wā, i te wā e whiriwhiri ana i tētahi waipara kore-waro, me whakaaro ki te hanganga o te waipara, kātahi ka whiriwhiri i tētahi e tika ana (tote rino, tote konumohe, tote rino-konumohe rānei, tote silicon-konumohe, tote silicon-ferric, me ētahi atu); ko ngā waipara polymer kore-waro ko:pūhaumāota polyaluminium (PAC), te konupūmā polyaluminium (PAS), te whanariki polyaluminium (Ngā Pac) mete whanariki polyferric (PFS), me ētahi atu. I roto i ēnei, ko ngā PAC me ngā PAS e tino kitea ana, he pai ō rātou āhuatanga o te urutau ki ngā huringa o te kounga wai e tukatukahia ana e ngā matū maimoatanga wai mata, he pai ngā pānga whakapūmau me te purenga, me te iti o te utu o ngā matū.
I te wā e whiriwhiri ana i tētahi mea whakapūkara rauropi (pēnei i:PAM polyacrylamide), ko te nuinga o te wā ka whakawhirinaki ki te whakamahinga o te polyacrylamide anionic, te polyacrylamide cationic, te polyacrylamide nonionic rānei. Ko ngā polyacrylamide anionic e hangai ana ki te nui o te waikura. Ko te whiriwhiri i ngā kationa ka whakamahia whānuitia i roto i te whakamaroke paru. He mea tino nui te whiriwhiri i te polyacrylamide cationic. Ko ngā tipu maimoatanga paru o ngā tāone e whakamahi ana i te polyacrylamide cationic reo-kaha. Ko ngā kationa ngoikore ka whakamahia whānuitia mō te whakamaroke paru i roto i ngā tipu hanga pepa me te tā me te tae, ā, ko ngā wai para rongoā ka whakamahia whānuitia. Kōwhiria ngā kationa kaha me ētahi atu. He āhuatanga motuhake tō ia momo wai para. Ko te polyacrylamide kore-ionic ka whakamahia whānuitia i raro i ngā āhuatanga waikawa ngoikore, ā, ko te PAM kore-ionic ka whakamahia whānuitia i roto i ngā wheketere tā me te tae.
Ngā kaiwhakarato kaihoko maimoatanga waie kī ana me whakatau te kōwhiringa o ēnei matū whakapūkara katoa kia rite ki te whakamātautau. I roto i te whakamātautau, whakatauhia te nui o te horopeta tata, tirohia te tere o te whakapūkara me te taunga, tatauhia te utu maimoatanga, kātahi ka whiriwhiri i tētahi kaihoko whakapūkara ōhanga me te tika.
