Ko te wai para o te whare patu kararehe tētahi o ngā wai para ahumahi tino uaua ki te tukatuka nā te mea he nui ngā totoka i whakatārewatia, ngā pūmua, ngā ngako, te hinu, ngā toenga toto, me ngā mea rauropi. Ka whai wāhi ēnei poke ki te pikinga o te paru, te hiahia matū hāora (COD), me te hiahia matū hāora (BOD), ka nui te tono ki ngā tukanga toto totoka me te toto totoka.
Mō te nuinga o ngā whare maimoatanga wai para, ko te konupūmā whanariki tonu te matū whakapūmau matua nā te mea e wātea ana, e iti ana hoki te utu mō ia wae. Heoi, ko te maimoatanga o ngā wai para uaua o ngā whare patu kararehe he maha ngā wā e hiahiatia ana he nui ngā horopeta, e piki ake ai te whakamahinga matū, te whakaputa paru, me ngā utu whakahaere.
E whakaatu ana tēnei rangahau take i ngā hua i tutukihia e tētahi tukatuka heihei ahumahi i arotake i tā mātou hua PDADMAC (PolyDiallyl Dimethyl Ammonium Chloride) hei wāhanga o tana kaupapa maimoatanga o nāianei. I tukuna e mātou te hua me ngā taunakitanga tono i runga i ngā āhuatanga whakahaere a te kiritaki. I whakahaerehia e te kiritaki ngā whakamātautau tipu, ā, i whakaritea te mahi ki tana tukanga maimoatanga tuku iho.
I whakaatuhia e ngā hua ka taea te whakatutuki i tētahi horopeta maimoatanga iti ake, me te whakaiti i te whakapaunga matū katoa, ka whakarato i ngā hua ōhanga ka taea te ine me te kore e whakararu i te mahi maimoatanga.
Papamuri Ahumahi: Te Utaina Parakino Teitei me te Hiahia ki ngā Whakakoi
