I te mea kei te piki haere te kaha o ngā whakaritenga tiaki taiao me te uaua haere o te maimoatanga waipara ā-umanga, ko te polydimethyldiallylammonium chloride (PDADMAC, tātai matū: [(C₈H₁₆NCl)ₙ])(https://www.cleanwat.com/poly-dadmac/)kei te huri hei hua matua. Nā ōna āhuatanga whai hua ki te whakapūmau i te wai, tōna ngāwari ki te whakamahi, me tōna atawhai ki te taiao, kua whānuitia te whakamahinga mō te purenga wai pūtake me te maimoatanga wai para.
Whakataki Hua
Kei roto i te pūmua ngā rōpū kationika kaha me ngā rōpū mimiti hohe. Mā te whakakore i te utu me te piriti mimiti, ka whakararuraru, ka whakapūpū hoki i ngā matūriki iri me ngā matū wairewa-wai kei roto ngā rōpū utu kino i roto i te wai, e whakaatu ana i te whai huatanga nui ki te tango tae, te whakahoromata, me te tango i ngā mea rauropi. He iti noa te horopeta e hiahiatia ana mō tēnei hua, he nui ngā pūpū ka puta, ka tere te tau, ā, he iti noa te paru e toe ana, ka iti noa te paru. Ka mahi hoki i roto i te whānuitanga pH o te 4-10. Kāore he kakara, kāore he reka, ā, kāore he paitini, he pai mō te whānuitanga o ngā tono purenga wai pūtake me te maimoatanga wai para.

Whakamahinga
Mēnā ka whakamahia ko ia anake, me whakarite he otinga whakaranu. Ko te kukū noa ko te 0.5%-5% (e pā ana ki te nui o ngā mea totoka).
I te wā e tukatukahia ana ngā puna wai me ngā wai para rerekē, me whakatau te horopeta i runga i te paru me te kukū o te wai kua tukatukahia. Ka taea te whakatau i te horopeta whakamutunga mā roto i ngā whakamātautau whakamātautau.
Me āta whiriwhiri te wāhi tāpiri me te tere whakaoho kia ōrite ai te ranunga ki te rauemi, me te karo hoki i te pakaru o te para.
He pai ake te tāpiri tonu.
Ngā tono
