Ko te maimoatanga wai para o ngā maina tētahi o ngā wāhanga tino uaua o te whakahaere wai ahumahi.Polyacrylamide(PAM), hei mea whakapūkara tino whai hua, he mea nui tana mahi i roto i te maimoatanga waipara o te keri. Heoi, kāore e pai ana ngā hua PAM katoa mō te maimoatanga waipara o te keri. Ko te whiriwhiri i te momo tika, te taumaha ngota, te matotoru o te utu, me te tikanga tono ka pā tika ki te whai huatanga o te maimoatanga, te whai huatanga o te utu, me te tutuki i ngā paerewa tukunga waipara.
Ka whakamāramahia e tēnei tuhinga te whiriwhiri i te hua PAM tika mō ngā matea maimoatanga waipara o te keri, hei āwhina i ngā kaihangarau, i ngā tīma hoko, me ngā kaiwhakahaere tipu ki te whakatau whai whakaaro.
Te Mārama ki ngā Āhuatanga o te Wai Para o te Keri
He maha ngā wā ka kitea i roto i ngā wai para keri he nui ngā totoka iri, ngā konganuku taumaha, ngā matūriki angiangi, me ngā toenga matū. He mea nui kia mārama ki ngā āhuatanga o te wai para keri i mua i te whiriwhiri i te PAM. He rerekē ngā momo wai para ka puta mai i ngā mahi keri rerekē:
Ngā Pūtake Noa o te Wai Para o te Keri
- ▶ Te keri waro me te horoi
