Pūhaumāota Polyaluminium, e whakarapopototia ana ko te PAC, he momo whakakōkī pūmua kore-waro. He āhuatanga tōna nā tōna kiato utu nui me tōna hanganga pūmua, e tino whai hua ai ki te whakakōkī me te whakapūpū i ngā poke i roto i te wai. He rerekē ki ngā whakakōkī tuku iho pērā i te konumohe, he whai hua te mahi a te PAC puta noa i te whānuitanga pH whānui, ā, he iti ake ngā hua paru e puta mai ana, e waiho ana hei huarahi pai mō te taiao.
Tikanga Mahi
Ko te mahi matua a te PAC i roto i te maimoatanga wai he whakakorekore me te whakakotahi i ngā matūriki iti kua whakatarewahia, ngā colloid, me ngā mea rauropi. Ka taea te wehewehe i tēnei tukanga, e mōhiotia ana ko te coagulation me te flocculation, kia maha ngā wāhanga:
1. Te Whakapūmau: Ina tāpirihia te PAC ki te wai, ka whakakorengia e ōna katote polyaluminium tino kaha ngā utu kino i runga i te mata o ngā matūriki e iri ana. Ka whakaitihia e tēnei whakakorenga ngā kaha pana i waenga i ngā matūriki, ka taea ai e rātou te whakatata mai.
2. Te Whakapūpūnga: Whai muri i te whakapūpūnga, ka huihui ngā matūriki kua whakakorengia hei hanga i ngā pūpūnga nui ake. Mā te āhua pūhui o te PAC ka āwhina i te hono i ngā matūriki, ka hangaia he pūpūnga nui ka taea te tango ngāwari.
3. Te Whakatakotoranga me te Tātari: Ka tere te taunga o ngā putunga nui i hangaia i te wā o te whakatakotoranga nā te kaha o te kaha. Mā tēnei tukanga whakatakoto putunga ka tangohia he wāhanga nui o ngā poke. Ka taea te tango i ngā putunga e toe ana mā te tātari, ā, ka puta he wai mārama, he wai ma.
Ngā Painga o te PAC
PACHe maha ngā painga o tēnei i ngā mea whakakōkī wai tuku iho, ā, ka piki haere tōna rongonui i roto i te maimoatanga wai:
- Whai Huatanga: He tino whai hua te PAC ki te tango i te whānuitanga o ngā poke, tae atu ki ngā totoka iri, ngā mea rauropi, tae atu ki ētahi konganuku taumaha. Mā tōna whai huatanga ka whakaitihia te hiahia mō ngā matū me ngā tukanga tāpiri.
- Awhe pH Whānui: He rerekē ki ētahi atu matū whakapūmau e hiahia ana ki te whakahaere pH tika, he pai te mahi a te PAC puta noa i te whānuitanga o te pH, e māmā ake ai te tukanga maimoatanga.
- Te Whakaiti i te Putanga o te Para: Ko tētahi o ngā painga nui o te PAC ko te whakaiti i te nui o te para e puta ana i te wā e tukatukahia ana. Mā tēnei whakaiti ka whakaitihia ngā utu whakakorenga me te whakaiti i te pānga ki te taiao.
- Te Whai Hua o te Utu: Ahakoa he nui ake te utu tīmatanga o te PAC ki ētahi atu matū whakapūkara tuku iho, nā te pai o te mahi me te iti o ngā whakaritenga horopeta ka hua ake he penapena utu whānui mō ngā whakaurunga maimoatanga wai.
Ngā Whakapūkara PAC He whanaketanga nui tēnei i roto i te hangarau maimoatanga wai. Nā tōna kaha ki te tango pai i ngā poke, me ngā painga taiao me te ōhanga, ka tū te PAC hei pou tokomanawa i roto i te rapunga mō te wai ma, haumaru hoki. I te mea he nui ake ngā hapori me ngā ahumahi e awhi ana i tēnei otinga auaha, ka mārama ake te ara ki tētahi heke mai hauora me te pumau.
