Pehea e wehe ai ka Polyaluminium chloride i nā mea haumia mai ka wai?

Polyaluminium Chloride, i hoʻopau pinepine ʻia ʻo PAC, he ʻano coagulant polymer inorganic. Hōʻike ʻia ʻo ia e kona kiʻekiʻe kiʻekiʻe a me ka hoʻolālā polymeric, kahi e hana maikaʻi ai i ka coagulating a me ka flocculating contaminants i ka wai. ʻAʻole like me nā coagulants kuʻuna e like me ka alum, hana maikaʻi ʻo PAC ma waena o kahi ākea pH ākea a hoʻohua i ka liʻiliʻi liʻiliʻi o nā huahana e pili ana i ka lepo, e lilo ia i mea ʻokoʻa e pili ana i ke kaiapuni.

Mechanism of Action

ʻO ka hana nui o ka PAC i ka mālama wai ʻo ia ka hoʻohaunaele a hōʻuluʻulu i nā mea i hoʻokuʻu ʻia, nā colloids, a me nā mea ola. ʻO kēia kaʻina hana, i kapa ʻia ʻo ka coagulation a me ka flocculation, hiki ke hoʻokaʻawale ʻia i loko o kekahi mau pae:

1. Coagulation: Ke hoʻohui ʻia ka PAC i ka wai, ʻo kāna mau ion polyaluminium i hoʻopiʻi nui ʻia e hoʻokaʻawale i nā hoʻopiʻi maikaʻi ʻole ma ka ʻili o nā mea i hoʻokuʻu ʻia. ʻO kēia neutralization e hōʻemi ana i nā ikaika repulsive ma waena o nā ʻāpana, e ʻae iā lākou e hoʻokokoke pū.

2. Flocculation: Ma hope o ka coagulation, hoʻohui ʻia nā mea i hoʻokaʻawale ʻia e hana i nā flocs nui aʻe. ʻO ke ʻano polymeric o PAC e kōkua i ka hoʻopili ʻana i nā ʻāpana, e hana ana i nā flocs nui i hiki ke wehe maʻalahi.

3. Sedimentation and Filtration: ʻO nā flocs nui i hana ʻia i ka wā o ka flocculation e noho wikiwiki ma muli o ka umekaumaha. Hoʻopau maikaʻi kēia kaʻina hana sedimentation i kahi hapa nui o nā mea haumia. Hiki ke hoʻoneʻe ʻia nā flocs i koe ma o ka kānana ʻana, e hopena i ka wai maʻemaʻe a maʻemaʻe.

Nā pōmaikaʻi o PAC

PAChāʻawi i kekahi mau mea maikaʻi ma mua o nā coagulants kuʻuna, e hāʻawi ana i kona ulu nui ʻana i ka mālama wai:

- ʻO ka maikaʻi: ʻoi aku ka maikaʻi o ka PAC i ka wehe ʻana i ka nui o nā mea haumia, me nā mea paʻa i hoʻopaʻa ʻia, nā mea kūlohelohe, a me kekahi mau metala kaumaha. Hoʻemi kona kūpono i ka pono o nā kemika a me nā kaʻina hana.

- Ka laulā pH ākea: ʻAʻole like me kekahi mau coagulants e koi ana i ka mana pH pololei, hana maikaʻi ʻo PAC ma kahi ākea pH ākea, e hoʻomaʻamaʻa i ke kaʻina hana.

- Hoʻoemi ʻia ka Sludge Production: ʻO kekahi o nā pōmaikaʻi koʻikoʻi o ka PAC ʻo ka hoʻemi ʻana o ka nui o ka lepo i hana ʻia i ka wā o ka mālama ʻana. Hoʻemi kēia hoʻohaʻahaʻa i nā kumukūʻai hoʻolei a hoʻemi i ka hopena o ke kaiapuni.

- Uku Uku: ʻOiai ʻoi aku ka nui o ke kumukūʻai o ka PAC ma mua o kekahi mau coagulants kuʻuna, ʻo kāna hana ʻoi aku ka maikaʻi a me nā koi haʻahaʻa haʻahaʻa e hopena pinepine i nā kumukūʻai holoʻokoʻa no nā hale mālama wai.

PAC Flocculants hōʻike i kahi holomua nui i ka ʻenehana mālama wai. ʻO kona hiki ke wehe pono i nā mea haumia, i hui pū ʻia me nā pōmaikaʻi kaiapuni a me ka hoʻokele waiwai, hoʻonoho iā PAC i pōhaku kihi i ka ʻimi ʻana i ka wai maʻemaʻe a palekana. I ka nui o nā kaiāulu a me nā ʻoihana e hoʻokomo i kēia hoʻonā hou, ʻoi aku ka maʻalahi o ke ala i kahi olakino olakino a hoʻomau.
