Ngā matū maimoatanga paru

He tukanga uaua te maimoatanga wai para e hiahia ana ki te whakamahi i ngā momo matū hei āwhina i te purenga o te wai. Ko ngā mea whakapūkara tetahi o ngā matū nui e whai wāhi nui ana ki te tukanga maimoatanga waipara. Ka whakamāramahia e tēnei tuhinga te horopeta o ngā matū maimoatanga waipara, ngā ahumahi whakamahinga o ngā mea whakapūkara i roto i te maimoatanga waipara, te tūranga o ngā matū waipara, me ngā whakatūpato mō te whakamahi i ngā mea whakapūkara.

Ko te horopeta o ngā matū maimoatanga paru e whakawhirinaki ana ki te kounga o te paru, te tukanga maimoatanga me ngā āhuatanga o nāianei. Anei ngā tauira o ngā horopeta o ētahi matū maimoatanga paru noa:

Pūhaumāota Polyaluminium (PAC):He mea whakamahi noa hei whakapūkara, ka taea te tauhohe ki ngā matūriki korori kua utua kinotia hei whakaputa i ngā micelle hauwaiwai e tau ana hei tango i ngā totoka iri me ngā katote konganuku taumaha. I raro i ngā āhuatanga noa, ko te horopeta mō ia tana wai mata he tata ki te tekau karamu, engari me whakarerekē te horopeta tuturu kia rite ki te kounga o te wai mata me ngā āhuatanga o te tukanga.

Polyacrylamide (PAM):e whakamahia ana hei whakapūmau i te piri me te pumau o te para. I te nuinga o te wā ka whakamahia ngātahi me te polyaluminium chloride, ko te horopeta mō ia tana wai mata he torutoru karamu pea, engari me whakarerekē te horopeta tuturu kia rite ki ngā āhuatanga o te tukanga me ngā momo poke.

He whānuitia te whakamahinga o ngā flocculants i roto i te maimoatanga wai para, tae atu ki ēnei wāhanga matua:

Te maimoatanga waipara ahumahi: He nui ngā matū totoka iri, ngā katote konganuku taumaha me ngā poke rauropi kei roto i ngā waipara ahumahi. Mā te whakamahi i ngā mea whakapūkara ka taea te tango pai i ēnei poke me te pure i te waipara.

Te maimoatanga parakaingaki o te whare: He nui ngā mea rauropi me ngā mea totoka kua whakatārewatia kei roto i te parakaingaki o te whare. Mā te whakamahi i ngā mea whakapūkara ka taea te tango i ēnei poke me te whakapai ake i te kounga o te wai.

Te maimoatanga wai para o te pāmu: He nui ngā mea rauropi, te hauota haukini me ētahi atu matū kino kei roto i te wai para o te pāmu. Mā te whakamahi i ngā mea whakapūkara ka taea te tango pai i ēnei poke me te whakapai ake i te kounga o te wai.

Para wai ahumahi: Mā te whakamahinga o ngā mea whakarewa ka taea te tango i ngā totoka iri, ngā katote konganuku taumaha me ngā poke waro i roto i te wai, ā, ka whakapai ake i te kounga o te wai.

Ko ngā mahi matua a ngā matū parakaingaki ko ēnei wāhanga e whai ake nei:

Te tango i ngā totoka iri: Mā te mahi a ngā mea whakarewa wai, ka huihuia ngā totoka iri i roto i te wai para hei puranga hei whakahaere i te whakapūtake me te tātari.

Te tango i ngā katote konganuku taumaha: Mā te mahi a ngā mea whakarewa, ka hurihia ngā katote konganuku taumaha i roto i te wai para hei putunga hauwai hei tango ngāwari.

Te tango i ngā poke rauropi: Mā te mahi a ngā mea whakarewa, ka hurihia ngā poke rauropi i roto i te wai para hei putunga hauwai, ka waikuratia rānei hei ētahi atu matū kia māmā ai te tango.

Te whakatikatika pH: Te whakatikatika i te pH o te wai para mā te mahi a te kawakore, te waikawa rānei hei pure i te wai para.

Ngā mea hei mōhio māu i te wā e whakamahi ana i ngā flocculants:

Kōwhiria te wai whakapūkara tika: He rerekē ngā mahi me ngā pānga o ngā wai whakapūkara rerekē. He mea tika kia whiriwhiria te wai whakapūkara tika i runga i te āhuatanga tūturu.

Te whakahaere i te horopeta o te rongoā: Ka pāngia te hua e te korenga o te horopeta, ā, ka pāngia te nui o te horopeta e te maumau me te ngaronga pūtea. Nō reira, me whakahaere te horopeta tika i runga i te āhuatanga tūturu.

Whakaohokia kia pai: Whakaohokia te mea whakaranu me te wai kia tino memeha, kia tauhohe hoki.

Kia tūpato ki te pāmahana me te uara pH: He pānga te pāmahana me te uara pH ki te pānga o te flocculant, ā, me āta whakahaere.
