He aha ka Poly Aluminum Chloride i hoʻohana ʻia no?

Polyaluminum Chloride(PAC) he polymer molekala kiʻekiʻe me ke ʻano kemika maʻamau Al2(OH)nCl6-nm. Ma muli o kona ʻano kemika kū hoʻokahi, loaʻa iā ia ka laulā o nā noi ma nā ʻano āpau. Lawe kēia ʻatikala iā ʻoe i loko o ke kula e aʻo i nā hoʻohana kikoʻī o kēia pūhui.

ʻO ka mea mua, loiloi nui ʻo PAC i ka mālama wai. Hiki iā ia ke hoʻoneʻe maikaʻi i nā mea paʻa i hoʻopaʻa ʻia, nā mea colloidal, nā mea ola ʻole, a me nā ʻāpana nui loa i ka wai. Loaʻa kēia ma o kahi kaʻina i kapa ʻia he coagulant, kahi e hana ai ka PAC ma ke ʻano he coagulant. Hoʻokaʻawale ia i nā hale kiaʻi o luna, e hōʻuluʻulu iā lākou i loko o nā ʻāpana nui a hiki ke hoʻokaʻawale ʻia mai ka wai. ʻOi aku ka maʻemaʻe o ka hopena, ka wai palekana e kū ana i nā kūlana maikaʻi no nā ʻano noi like ʻole, me ka wai ʻoihana. Hoʻohana pū ʻia ʻo PAC i nā kaʻina hoʻomaʻemaʻe wai e hoʻopau i nā mea paʻa i hoʻopaʻa ʻia a hoʻomaikaʻi i ka maikaʻi o ka wai ma o ka hōʻemi ʻana i ka turbidity. Hoʻohana maʻamau ia i ka hui pū ʻana me nā kemika mālama wai ʻē aʻe, e like me PAM, etc., no ka loaʻa ʻana o nā hopena maikaʻi loa.

Hiki ke hoʻohana ʻia ka polyaluminum chloride (PAC) ma ke ʻano he flocculant i ka ʻoihana hana pepa e mālama i ka wai a me ka wai maʻemaʻe. ʻOi aku ka maikaʻi o ka PAC a me ke kumu kūʻai haʻahaʻa, a makemake ʻia e nā mea hana pepa. Eia kekahi, lawelawe ia ma ke ʻano he precipitant, paʻa a me ke kānana kōkua no ka rosin-neutral sizing, hiki ke hoʻomaikaʻi i ka hopena sizing a pale i ka contamination o nā lole mīkini pepa, slurries papermaking a me nā ʻōnaehana wai keʻokeʻo e nā huahana hydrolyzate.

Hana maikaʻi nā flocculants polyaluminum chloride i ka ʻoihana mining. Hoʻohana ʻia ia i ka holoi ʻana i nā ores a hana nui i ka hana hoʻokaʻawale mineral. Ma kekahi ʻaoʻao, hoʻokaʻawale maikaʻi ia i ka wai mai ka gangue e maʻalahi i ka hoʻohana hou ʻana i ka wai; ma ka ʻaoʻao ʻē aʻe, hoʻomaloʻo ia i ka sludge i hana ʻia.

Ma ka ʻoihana ʻaila, noho pū ʻo PAC i kahi kūlana koʻikoʻi. Hoʻohana ʻia ia e wehe i nā haumia mai ka ʻaila i ka wā o ka ʻili a me ka hoʻomaʻemaʻe ʻana i ka ʻaila. ʻAʻole hiki iā ia ke hoʻoneʻe pono i nā mea organik insoluble, nā metala a me nā mea ʻino ʻē aʻe i loko o ka wai ʻōpala, akā hoʻopau pū kekahi a hoʻoneʻe i nā kulu ʻaila i hoʻokuʻu ʻia mai ka wai. I ka ʻeli ʻana i nā pūnāwai aila, kōkua pū ka PAC i ka hoʻopaʻa ʻana i ka luawai a pale i ka pōʻino. Ma ka hoʻokomo ʻana i loko o ka luawai, e kūʻē i ke kaomi hoʻokumu ʻana, e hōʻemi ana i ka pōʻino. ʻO kēia ma muli o nā waiwai o PAC ma ke ʻano he gelling agent a me ka tackifier.

ʻO ka ʻoihana paʻi lole a me ka ʻoihana hoʻoluʻu kekahi ʻano noi nui o PAC. No ka mea ʻo ka wai ʻino i hana ʻia e kēia ʻoihana he mau hiʻohiʻona o ka leo nui, ka waihoʻoluʻu hohonu, a me ka ʻike kiʻekiʻe o nā mea haumia organik, lilo ia i mea paʻakikī ke mālama. Eia nō naʻe, ma o ka hana a PAC, ikaika a nui nā pua alum i ka wā o ka mālama ʻana i ka wai ʻino, noho wikiwiki, a kupaianaha ka hopena lapaʻau.

Ma waho aʻe o nā kahua i luna aʻe nei, hoʻokani pū ka PAC i ka ʻoihana kemika i kēlā me kēia lā, ka mahiʻai, ka iʻa a me nā māla ʻē aʻe. Hiki ke hoʻohana ʻia ka hoʻohana nui ʻana o PAC i kāna mau waiwai kemika a me ka versatility. ʻO kona hiki ke hana ma ke ʻano he coagulant, stabilizer, a me ka tackifier he mea waiwai nui ia i nā ʻoihana like ʻole. Ke hoʻomau nei ka ulu ʻana o ka ʻenehana a me ka ʻoihana, ʻo ka hana a PAC i ka hoʻokō ʻana i kēia mau pono e hoʻoikaika hou i kona kūlana ma ke ʻano he mea koʻikoʻi i nā kaʻina hana ʻenehana.
