Āhuatanga:
1. He hou, he kounga teitei me te pai o te momo tote ferric polymer flocculant;
2. He pai te whakakotahitanga, nga puawai kowau mato me te tere whakatau;
3 He pai te painga o te purenga wai me te pai o te wai.Karekau he matū kino penei i te konumohe, te maaota me nga katote whakarewa taumaha, kaore hoki he whakawhitinga wai o nga katote rino.He kore-paitini, he kino, he haumaru me te pono;
4. He mea whakamiharo ki te tango turbidity, decolorization, tango hinu, dehydration, bacteria removal, deodorization, algae removing, and removing of COD, BOD and heavy metal ions in water;
5 Ko te awhe uara pH o te tinana wai e tika ana ko te 4-11, ko te awhe uara pH tino pai ko te 6-9.I muri i te purenga, he iti te huringa o te uara pH me te katoa o te alkalinity o te wai mata, a he iti te waikura ki nga taputapu maimoatanga;
6. He mea whakamiharo te awenga purenga o te micro polluted, te pukohue kei roto, te iti o te pāmahana me te iti turbidity te wai mata, ina koa mo te wai mata o te waikura nui;
