PAM Flocculant: he matū kaha mō te maimoatanga wai ahumahi

PolyacrylamideKo te (PAM) he pūhui hangai wai-aroha e whakamahia whānuitia ana i roto i ngā tukanga maimoatanga wai. Ko te nuinga o te wā ka whakamahia hei flocculant me te coagulant, he matū e meinga ai ngā matūriki iri i roto i te wai kia huihui hei flocs nui ake, ā, mā te reira ka āwhina i te tango atu mā te whakamārama, te tātari rānei. I runga i te kounga o te wai para, whakamahia te PAM cationic, anionic, kore-ionic rānei. He maha ngā painga o te Polyacrylamide i roto i te maimoatanga wai, tae atu ki tōna whai huatanga i runga i te whānuitanga o te pH, te pāmahana, me ngā awhe turbidity. Ka taea te whakamātautau i te pānga coagulant mā te whakamahi i ngā whakamātautau Jar, i te ine turbidity rānei.

Ka taea te whakamahi whānui i te polyacrylamide i roto i te maimoatanga wai ahumahi, te maimoatanga paru, te maimoatanga waipara, me ētahi atu. I roto i ngā whare maimoatanga wai, ka whakamahia te polyacrylamide i roto i ngā tukanga maha, tae atu ki te whakamārama tuatahi me te tuarua, te tātari, me te patu huakita. I roto i te tukanga whakamārama tuatahi, ka tāpirihia ki te wai mata hei whakatairanga i te taunga o ngā totoka i whakatārewatia, kātahi ka tangohia mā te whakatō, mā te whakamānu rānei. I roto i te whakamārama tuarua, ka whakamahia te polyacrylamide hei whakamārama ake i te wai kua rongoatia mā te tango i ngā totoka i whakatārewatia e toe ana me ngā mea rauropi kua mimitihia.

Ko te kaupapa mahi o tete whakapūkara polyacrylamideko: i muri i te tāpiri i te otinga PAM, ka piri te PAM ki ngā matūriki, ka hanga piriti i waenganui i a rātou. I roto i te puna taketake, ka piri ki te hanga i ngā para nui ake, ā, ka pōuri te wai i tēnei wā. I muri i te tipu me te matotoru o te maha o ngā para, ka heke haere, ka totohu mārire i roto i te wā, ā, ka mārama te paparanga o runga o te wai mata. Ka whakapai ake tēnei tukanga whakakotahi i ngā āhuatanga taunga o ngā matūriki, ka māmā ake te tango i a rātou i te wā e whakamārama ana, e tātari ana rānei. He maha ngā wā ka whakamahia te polyacrylamide me ētahi atu matū whakakoi me ngā matū whakakoi hei whakatutuki i te māramatanga me te mahi tātari tino pai.

He mea nui anō hoki te mahi a te polyacrylamide i roto i te tātari wai. He maha ngā wā ka whakamahia hei tātari-mua i roto i ngā tātari, i ētahi atu tikanga tātari ā-tinana rānei hei tango i ngā totoka i whakatārewatia me te paru. Mā te whakapai ake i te tango i ēnei matūriki, ka āwhina te polyacrylamide ki te whakarite kia mārama ake, kia parakore ake te tātari.

He pūhui pumau te polyacrylamide, kāore e paitini, ka pakaru mā roto i ngā tukanga taiao, i ngā tikanga maimoatanga koiora rānei. Me mōhio anō hoki, mā te wai i maringi ka tino pahekeheke te papa, ka hinga pea.

Heoi, ko te nui o te PAM e whakamahia ana e whakawhirinaki ana ki te momo wai para me te nui o ngā matūriki totoka i whakatārewatia, tae atu ki te aroaro o ētahi atu matū, waikawa, me ngā poke i roto i te wai. Tērā pea ka pā ēnei āhuatanga ki te pānga totoka o te PAM, nō reira me mahi ngā whakarerekētanga tika i te wā e whakamahia ana. Me āta whiriwhiri ngā hua PAM me ngā taumaha ngota ngota rerekē, ngā nekehanga ionic, me ngā horopeta mō ngā momo wai para rerekē.
