He wāhanga nui te whakamaroke i te paru i roto i te tukanga maimoatanga paru. Ko tōna kaupapa he tango pai i te wai i roto i te paru, kia iti ake ai te nui o te paru, kia iti ake ai hoki ngā utu whakakore me te wāhi whenua. I roto i tēnei tukanga, ko te whiriwhiri iKaiwhakarewa waiko te kī, me te PolyDADMAC, hei huarahi whai huaTe whakapūkara pūmua kationika, kei te piki haere te hiranga o tana mahi.
Tuatahi, me mārama tātou ki te hanganga me ngā āhuatanga o te paru. Ko te paru he paru totoka e puta ana i te wā e tukatukahia ana te paru. Kei roto ngā wāhanga matatini pēnei i ngā para koiora, ngā rōpū moroiti, ngā matūriki kore-ora me ngā korori. Ko ngā totoka iri i roto i te paru he utu kino, ā, ka panaia tetahi ki tetahi, i te mea ka whakakīia e te wai te waenganui o ngā totoka iri, nō reira ka eke te nui o te wai tuatahi o te paru ki te 95%. Ki te kore e tukatukahia tēnei paru i te wā tika, ka puta he parahanga tuarua ki te taiao. Nō reira, ko te huarahi ki te whakahaere pai i te whakamaroke paru kua noho hei take nui i roto i te mara o te maimoatanga paru.
I roto i te tukanga whakamaroke paru,Ngā mea whakapūkara mō te whakamaroke paruHe mea nui te pānga. Ka whakakotahi te wai whakapūkara i ngā matūriki ririki o te paru ki ngā matūriki nunui mā te whakakore hiko, te hononga mimiti, me ētahi atu, kia tere ake ai te tukanga whakatō me te whakamaroke. Hei hua matū e whakamahia ana mō te maimoatanga wai para me te whakamaroke paru, he pai te mahi a PolyDADMAC ki te whakamaroke paru nā tōna hanganga ngota ahurei me te kiato utu.
Nā te hanganga ngota o te PolyDADMAC ka nui te kaha o te utu me ngā āhuatanga mimiti pai rawa atu. I te wā o te tukanga whakamaroke paru, ka taea e te PolyDADMAC te mimiti tere ki runga i te mata o ngā matūriki paru, ka whakaiti i te kaha pana i waenga i ngā matūriki mā te whakakore hiko, ā, ka whakatairanga i te hanganga o ngā putunga nui ake i waenga i ngā matūriki. I taua wā anō, ka taea hoki e ngā mekameka ngota o te PolyDADMAC te hanga i tētahi hanganga whatunga whai hua, ka mauheretia ngā matūriki paru maha, ka pēhi i te wai mai i waenga i ngā matūriki paru, ka hanga i ngā puranga e ngāwari ana te whakamaroke, kia taea ai te whakaiti i te rahinga wai ki te 60-80%, ki raro iho rānei, ā, ka taea te whakaiti i te rahinga mā te 75-87%.
Ki te whakatauritea ki ngā mea whakapūkara kore-ora tuku iho, he nui ake te taumaha ngota me te mātotoru utu o te PolyDADMAC, ā, he kaha ake tōna kaha ki te whakapūkara. Hei tāpiri,PolyDADMACHe tino pai te mahi whakarewa, he ngāwari ki te whakamahi, ā, kāore e puta he parahanga tuarua. Kāore te PD e puta he parahanga pērā i te konumohe, nō reira ka taea te whakaiti i te nui o te paru tāpiri. Nā ēnei painga ka whānuitia ngā tono a PolyDADMAC i roto i te mara o te whakamaroke paru.
Nā te hanganga ngota o te PolyDADMAC ka nui te kaha o te utu, ā, ka tino pai hoki ōna āhuatanga mimiti. Ka taea e ngā rōpū cationic maha i runga i tōna mekameka ngota te tauhohe ki ngā rōpū anionic i runga i te mata o ngā matūriki paru hei hanga hononga ionic pumau, ka hua ake he mimiti kaha. Ehara i te mea ka āwhina noa tēnei mimiti ki te whakaiti i te ātete i waenga i ngā matūriki, engari ka āwhina anō hoki ki te hanga i ngā putunga nui ake.
Haunga te hanganga ngota me ngā āhuatanga utu o te PolyDADMAC, ko tōna kukū me te horopeta he mea nui anō hoki e pā ana ki te pānga o te maroke o te paru. I roto i tētahi whānuitanga, i te pikinga ake o te kukū o te PolyDADMAC, i te pikinga ake rānei o te horopeta, ka taea te whakapai ake i te mahi whakamaroke o te paru. Heoi, ki te nui rawa te kukū, te horopeta rānei, ka hua ake pea te pānga rerekē, ka hua ake he tiaki colloid, ka whakaitihia ai te pānga maroke. Nō reira, i roto i ngā mahi whaihua, me whakahaere he whakamātautau me te arotau i runga anō i te pūnaha maimoatanga paru me ngā āhuatanga paru motuhake hei whakatau i te kukū me te horopeta pai rawa atu o te PolyDADMAC.
