He taputapu maimoatanga wai whai hua, he pai hoki mō te taiao
I roto i te ao hou, kua riro te tiaki me te whakamahi i ngā rauemi wai hei kaupapa matua o te ao. I te tere haere o te ahumahi, kua piki haere te kino o te parahanga o ngā rauemi wai. Kua noho ko te huarahi ki te rongoā me te pure i ngā parahanga wai hei raruraru nui hei whakatau. I roto i tēnei horopaki, i puta mai ai te PAM polymer flocculant, ā, kua riro i te nuinga o ngā kaiwhakamahi te manakohanga nā ōna āhuatanga matū me te whai huatanga o te rongoā wai.
Ko te PAM, te ingoa katoa o te polyacrylamide, he polymer flocculant. He momo polymer teitei i hangaia mā te polymerization free radical o te acrylamide. He taumaha ngota teitei te hua, ā, ka taea te hanga i ngā matūriki flocculants nui, he pai te marara me te pumau i roto i te wai, ā, ka taea te mimiti me te tango i ngā mea kua tautau me ngā poke rewa i roto i te wai.
He tino māmā te tukanga tono o te whakapūkara polymer PAM. Tuatahi, ka tāpirihia te otinga PAM ki te wai hei rongoā, kātahi ka whakaranua te PAM me te wai mā te whakaoho, mā te mīhini rānei, kia puta he whakapūkara nui. Ka tau ēnei whakapūkara ki roto i te wai, ā, ka tutuki te kaupapa o te tango i ngā poke. Nā te pumau matū o te hua, ka taea te tuku tika i te wai kua rongoātia ki te taiao me te kore e hiahiatia he rongoā tuarua.
Ko ngā painga o tēnei hua ehara i te mea ko tōna whai huatanga ki te maimoatanga wai anake. Tuatahi, he iti ake te utu mō te whakamahi. Ki te whakatauritea ki ngā tikanga maimoatanga wai tuku iho, pērā i te whakatō, te tātari, me ētahi atu, he māmā ake, he iti ake hoki te ohanga o te whakamahinga o te hua. Tuarua, he iti ake te pānga o te hua ki te kounga o te wai. Kāore e whakarerekē i ngā āhuatanga matū o te wai, nō reira kāore e puta he parahanga tuarua ki te taiao. Hei whakamutunga, he pai te pānga maimoatanga o te hua, ka taea te tango pai i ngā mea i whakatārewatia me ngā poke rewa i roto i te wai, te whakapai ake i te mārama o te wai me ngā tohu rongo.
I te nuinga o te wā, he taputapu maimoatanga wai whai hua, he pai hoki mō te taiao te PAM polymer flocculant. Ehara i te mea ko tōna putanga mai anake he otinga hou hei whakaoti rapanga i te parahanga wai, engari he tautoko hangarau kaha hoki mō te whakatairanga i te whakahaere rauemi wai matomato me te pumau. I te heke mai, me te whanaketanga o te pūtaiao me te hangarau me te whakapai ake i te mōhiotanga ki te taiao, he take tā mātou ki te whakapono ka nui ake te mahi a te hua i roto i te mara o te maimoatanga wai.
