Te whakarewa polyacrylamide (PAM)He matū e whakamahia whānuitia ana i roto i ngā tukanga maimoatanga wai hei whakapai ake i te kounga o te wai me te whakarei ake i te whai huatanga o ngā momo tikanga maimoatanga. Kua rongonui tēnei pūmua maha-whakamahinga nā tōna kaha ki te tango i ngā poke me ngā matūriki iri i roto i te wai, ā, he mea nui tēnei hei wāhanga mō te whakatika i te parahanga wai me te whakarite i te wai haumaru me te ma mō ngā momo tono.
1. Tikanga Whakaheke:
E mōhiotia ana te PAM mō ōna āhuatanga whakapūpū tino pai. I roto i te maimoatanga wai, ko te whakapūpū e pā ana ki te tukanga whakakotahi i ngā matūriki colloidal hei hanga i ngā pūpū nui ake, ngāwari ki te tau. Ka tutuki tēnei i te PAM mā te whakakore i ngā utu kino i runga i ngā matūriki, te whakatairanga i te whakakotahitanga, me te hanga i ngā matūriki nui ake, taumaha ake ka taea te wehe ngāwari mai i te wai.
2. Te Whakarei Ake i te Whakatakotoranga:
Ko te mahi matua a te PAM i roto i te maimoatanga wai he whakarei ake i te tukanga whakapūpū. Mā te whakatairanga i te hanganga o ngā putunga nui ake, ka āwhina te PAM i te taunga o ngā matūriki iri, ngā putunga, me ngā poke i roto i te wai. Ka hua ake tēnei i ngā tere whakapūpū pai ake, ka taea ai te tango pai ake i ngā poke, ā, ka mārama ake te wai.
3. Te Whakamārama i te Wai:
He tino whai hua te PAM ki te whakamārama i te wai mā te tango i te paru me ngā totoka iri. Mā ōna āheinga ki te whakapūpū ka whai wāhi ki te hanganga o ngā paru nui ake, kiato ake, ka tere ake te taunga, ka waiho te wai kia mārama, kia kore hoki he poke e kitea ana. He mea nui tēnei mō ngā tono e hiahiatia ana te wai mārama, pērā i te maimoatanga wai inu me ngā tukanga ahumahi.
4. Te Whakahaere i te Horo o te Oneone:
Haunga te maimoatanga wai, ka whakamahia anō hoki te PAM hei whakahaere i te horo o te oneone. Ina whakamahia ki te oneone, ka honoa te PAM ki ngā matūriki, ka whakapiki i tō rātou piripono me te whakaiti i te tūponotanga o te horo. He mea nui tēnei whakamahinga i roto i ngā mahi ahuwhenua, hanga whare, me ngā kaupapa whakaora whenua, he mea nui te ārai i te horo o te oneone hei pupuri i te momona o te oneone me te ārai i te pirau o te taiao.
5. Te Arotau i te Whakapūpū:
Ka taea te whakamahi tahi me ngā matūriki whakapūmau i te PAM hei whakapai ake i te tukanga whakapūmau. Ka whakararuraru ngā matūriki i roto i te wai i ngā matūriki whakapūmau, ā, ka āwhina te PAM ki te hanga i ngā putunga nui ake, ka whakapai ake i te whai huatanga whānui o te whakapūmau. Mā tēnei mahi tahi ka pai ake ngā hua maimoatanga wai, inā koa te tango i ngā matūriki angiangi e uaua ana ki te whakakore mā te whakapūmau anake.
6. Te Maimoatanga Wai Utu-whai hua:
He iti te utu o te whakamahinga o te PAM i roto i te maimoatanga wai nā tōna kaha ki te whakarei ake i te mahi a ētahi atu matū me ngā tukanga maimoatanga. Mā te whakapai ake i ngā āhuatanga taunga o ngā matūriki, ka whakaitihia e te PAM te hiahia mō te nui rawa o ngā matū whakakoi, ka hua ake he penapena utu mō ngā tipu maimoatanga wai me ngā ahumahi e whai wāhi ana ki te purenga wai.
Hei whakarāpopototanga, he mahi nui tā te PAM flocculant i roto i te maimoatanga wai mā te whakatairanga i te flocculation, te whakarei ake i te oneone, me te whakamārama i te wai. Kāore i te maimoatanga wai anake tōna whakamahinga engari ko te whakahaere i te horo o te oneone, ā, he taputapu whai hua tēnei mō te aro atu ki ngā wero taiao. Ko te whakamahinga o te PAM i roto i ngā tukanga maimoatanga wai e whakaatu ana i tōna whai huatanga, tōna utu whai hua, me ōna takoha ki te whakarite kia uru atu ki te wai ma, haumaru hoki.
