Te whakamahinga o te PAC i roto i te umanga hanga pepa

He matū nui te Polyaluminum Chloride (PAC) i roto i te umanga hanga pepa, ā, he mea nui tēnei i roto i ngā wāhanga rerekē o te tukanga hanga pepa. He matū whakapūmau te PAC e whakamahia ana hei whakapai ake i te pupuri i ngā matūriki angiangi, ngā whakakī, me ngā muka, ā, ka whakapai ake i te whai huatanga me te kounga o te hanga pepa.

Te Whakapūpū me te Whakapūpū

Ko te mahi matua a te PAC i roto i te hanga pepa ko ōna āhuatanga whakapūmau me te whakapūpū. I roto i te tukanga hanga pepa, ka konatunatua te wai ki ngā muka cellulose hei hanga i tētahi paru. Kei roto i tēnei paru he nui o ngā matūriki angiangi me ngā matū waro rewa e tika ana kia tangohia hei hanga pepa kounga teitei. Ina tāpirihia te PAC ki te paru, ka whakakore i ngā utu kino i runga i ngā matūriki iri, ka meinga kia piri tahi hei puranga nui ake, hei ngā floc rānei. He tino āwhina tēnei tukanga ki te tango i ēnei matūriki angiangi i te wā o te tukanga whakaheke wai, ka hua ake he wai mārama ake, ā, ka pai ake te pupuri muka.

Te Pupuri me te Wairewa Whakapai Ake

He mea nui te pupuri i ngā muka me ngā whakakī i roto i te hanga pepa, nā te mea ka pā tika ki te kaha, te kakano, me te kounga whānui o te pepa. Ka whakapai ake te PAC i te pupuri i ēnei rauemi mā te hanga i ngā putunga nui ake ka taea te pupuri ngāwari ki runga i te waea mīhini pepa. Ehara i te mea ka whakarei ake i te kaha me te kounga o te pepa anake, engari ka whakaitihia hoki te nui o te ngaronga o ngā rauemi mata, ka hua ake he penapena utu. Hei tāpiri, ko te pai ake o te rerenga wai e whakahaeretia ana e te PAC ka whakaiti i te nui o te wai i roto i te pepa pepa, ā, ka whakaitihia te kaha e hiahiatia ana mō te whakamaroke me te whakarei ake i te whai huatanga whānui o te tukanga hanga pepa.

Te Whakapai Ake i te Kounga o te Pepa

He nui te whai wāhi a te PAC ki te whakapai ake i te kounga o te pepa. Mā te whakarei ake i te pupuri i ngā mea angiangi me ngā mea whakakī, ka āwhina te PAC ki te whakaputa pepa me te hanganga pai ake, te ōritetanga, me ngā āhuatanga o te mata. Ka hua ake tēnei i te pai ake o te tānga, te maeneene, me te āhua whānui o te pepa, kia pai ake ai mō ngā tono tā me te takai kounga teitei.

Te Whakaiti i te BOD me te COD i roto i te Hanga Pepa Te Maimoatanga Wai Para

Ko te Hiahia Hāora Matū (BOD) me te Hiahia Hāora Matū (COD) he ine i te nui o ngā mea rauropi kei roto i te wai para i hangaia e te tukanga hanga pepa. Ko ngā taumata tiketike o te BOD me te COD e tohu ana i te taumata teitei o te parahanga, ka kino pea ki te taiao. Ka whakaitihia e te PAC ngā taumata BOD me te COD mā te whakakotahi me te tango i ngā poke rauropi mai i te wai para. Ehara i te mea ka āwhina noa tēnei ki te whakatutuki i ngā ture taiao engari ka whakaitihia hoki ngā utu maimoatanga e pā ana ki te whakahaere wai para.

Hei whakarāpopototanga, he tāpiringa nui te polyaluminium chloride i roto i te umanga hanga pepa, he maha ngā painga e whakarei ake ana i te whai huatanga o te tukanga hanga pepa me te kounga o te hua whakamutunga. Ko ōna mahi i roto i te whakapūmau me te flocculation, te pupuri me te rerenga wai, te whakaiti i te BOD me te COD, me te whakapainga whānui o te kounga pepa e waiho ana hei wāhanga tino nui i roto i te hanga pepa hou.
