He aha te matū e whakamahia ana mō te Flocculation?

Te rere o te waiHe tukanga e whakamahia ana i roto i ngā momo ahumahi, inā koa i roto i te maimoatanga wai me te maimoatanga waipara, hei whakakotahi i ngā matūriki me ngā colloid i whakatārewatia hei matūriki floc nui ake. Mā tēnei ka taea te tango mā te whakatō, te tātari rānei. Ko ngā matū e whakamahia ana mō te flocculation e mōhiotia ana ko ngā flocculants. Ko tētahi o ngā flocculants e whakamahia whānuitia ana ko te polyacrylamide.

PolyacrylamideHe pūmua i hangaia mai i ngā monomer acrylamide. Kei roto i ngā momo āhua maha, tae atu ki te anionic, te cationic, me te kore-ionic, ia āhua me ōna whakamahinga motuhake. Ko te whiriwhiri i te momo polyacrylamide e whakawhirinaki ana ki te āhua o ngā matūriki i roto i te wai me te hua e hiahiatia ana o te tukanga flocculation.

He utu kino te polyacrylamide anionic, ā, he maha ngā wā ka whakamahia hei rongoā i ngā wai para kei roto ngā matūriki utu pai pērā i te uku me te mea rauropi. Ko te polyacrylamide cationic, i tētahi atu ringa, he utu pai, ā, he whai hua mō te rongoā i te wai me ngā matūriki utu kino pērā i ngā totoka iri me te paru. Kāore he utu o te polyacrylamide kore-ionic, ā, he pai mō te whakapūpū i te whānuitanga o ngā matūriki.

Ko te mahi a ngā matūriki polyacrylamide mā te piri ki te mata o ngā matūriki, ka hanga piriti i waenganui i a rātou, ka hanga i ngā matūriki nui ake. He māmā ake te taunga, te tātari rānei i ngā matūriki ka puta mai i te wai. Ko te polyacrylamide te mea e pai ake ana mō tōna taumaha ngota ngota, e whakarei ake ana i ōna pūkenga hono me te whakapūpū.

Haunga te polyacrylamide, ka whakamahia hoki ētahi atu matū mō te flocculation, i runga i ngā hiahia motuhake o te tukanga maimoatanga. Ko ngā flocculants inorganic, pērā iKonumohe Wheat(konumohe) me te konupora ferric, e whakamahia whānuitia ana i roto i te maimoatanga wai. Ka hangaia e ēnei matū he putunga hauwai konukōre ina tāpirihia ki te wai, hei āwhina i te tango i ngā matūriki iri.

Ko te konumohe, inā koa, kua whakamahia whānuitia mō te whakamārama wai mō ngā tau maha. Ina tāpirihia ki te wai, ka waikura te konumohe, ka hanga he putunga konumohe hauwai hei hopu i ngā poke. Kātahi ka taea te tau ngā putunga, ā, ka taea te wehe i te wai kua whakamāramahia mai i te paru.

He taahiraa nui te whakapūkara i roto i ngā tukanga maimoatanga wai, e whakarite ana i te tango i ngā poke me te whakaputa wai ma. Ko te whiriwhiri i te whakapūkara e whakawhirinaki ana ki ngā āhuatanga pēnei i ngā āhuatanga o te wai e tukatukahia ana, te momo matūriki kei roto, me te putanga maimoatanga e hiahiatia ana. He mea nui te mahi a te Polyacrylamide me ētahi atu whakapūkara ki te whakarei ake i te whai huatanga o ngā pūnaha maimoatanga wai me te wai para, e whai wāhi ana ki te whakarato wai haumaru me te wai inu mō ngā kaupapa maha.
