Polyaluminum Chloride (PAC)
ʻO ka Polyaluminum chloride (PAC), i kapa ʻia ʻo polyaluminum no ka pōkole, Poly Aluminium Chloride dosing In Water Treatment, he ʻano kemika ʻo Al₂Cln(OH)₆-n. ʻO ka Polyaluminum Chloride Coagulant kahi mea mālama wai polymer inorganic me ke kaumaha molekala nui a me ka uku kiʻekiʻe i hana ʻia e ka hopena bridging o nā ions hydroxide a me ka polymerization o nā anions polyvalent. Hiki ke hoʻokaʻawale ʻia ka Poly Aluminium Chloride Pac i paʻa a me ka wai i ke ʻano. Polyaluminum paʻa Melemele, hina-ʻōmaʻomaʻo, pauka ʻeleʻele ʻeleʻele. Hoʻopilikia maʻalahi ʻia ka wai Pac e ka makū a maʻalahi hoʻi e hoʻoheheʻe ʻia i ka wai. Hoʻopili ʻia ke kaʻina hana hydrolysis me nā kaʻina hana kino a me ke kemika e like me ka electrochemistry, agglutination, adsorption, a me ka precipitation, a he mau waiwai adsorption bridging ikaika.
1. ʻAno hana
ʻO ka hopena wai o ka kemika PAC he huahana hydrolysis ma waena o FeCl₃ a me Al(OH)₃, me ka hoʻouka colloidal, no laila he adsorption ikaika kona i nā mea paʻa i hoʻokuʻu ʻia i loko o ka wai, i mea e hoʻokō ai i ke kumu o ka hoʻopili ʻana i nā mea paʻa i hoʻokuʻu ʻia i loko o ka wai.
2. Nā Hiʻohiʻona Huahana
● Paʻa ka kemika o ka Polyaluminum chloride i ka mahana o ka lumi, a ʻaʻole e pala ma hope o ka mālama ʻana i ka wā lōʻihi. Hoʻopili maʻalahi ka polyaluminum paʻa i hōʻike ʻia i ka makū, akā ʻaʻole e pala, a ʻaʻohe mea ʻawahia a ʻino ʻole.
● ʻO ka waiwai pH o ka pae wai kūpono he 4-14, akā ʻo ka waiwai pH o ka pae mālama kūpono loa he 6-8.
● Loaʻa i ka Poly Aluminium Chloride Powder nā ʻano o ka liʻiliʻi liʻiliʻi, ke kumukūʻai haʻahaʻa, ka hana kiʻekiʻe, ka hana maʻalahi, ka hoʻohana ākea a me ka haʻahaʻa corrosiveness.
Polyacrylamide (PAM)
ʻO Polyacrylamide (PAM) /nonionic polyacrylamide/cation polyacrylamide/anionic polyacrylamide, ʻo ia hoʻi ka flocculant No. 3, he polymer linear wai-soluble i hoʻokumu ʻia e ka polymerization radical manuahi o ka monomer acrylamide (AM). Ke kaʻina hana coagulation a me ka flocculation i ka mālama ʻana i ka wai, loaʻa i ka Polyacrylamide sds ka flocculation maikaʻi a hiki ke hōʻemi i ka friction ma waena o nā wai Hiki ke hoʻokaʻawale ʻia ke kū'ē i ʻehā mau ʻano: anionic, cationic, nonionic a me amphoteric e like me nā waiwai ionic.
He ʻāpana pauka keʻokeʻo ka Polyacrylamide, hiki ke hoʻoheheʻe ʻia i loko o ka wai ma kekahi ʻano, like a moakaka ka hopena wai, a piʻi nui ka mānoanoa o ka hopena wai me ka hoʻonui ʻia o ke kaumaha molekala pili o ka polymer. ʻAʻole hiki ke hoʻoheheʻe ʻia ka PAM i ka hapa nui o nā mea hoʻoheheʻe organik, e like me ka formaldehyde, ethanol, acetone, ether, a pēlā aku.
1. ʻAno hana
He polymer a polyelectrolyte paha ka Polyacrylamide e hoʻoheheʻe ʻia i ka wai. Aia kekahi mau hui polar i loko o ke kaulahao molekala PAM, hiki ke hoʻopili i nā ʻāpana paʻa i kau ʻia i loko o ka wai kahe, hana i nā alahaka ma waena o nā ʻāpana a i ʻole ma o ka hoʻemi ʻana i ka uku, i hiki ai i nā ʻāpana ke hoʻohuihui e hana i nā flocs nui. No laila, hiki i ka polyacrylamide ke hoʻolalelale i nā mea paʻa i kau ʻia. ʻO ka sedimentation o nā ʻāpana waena he hopena maopopo loa ia o ka hoʻolalelale ʻana i ka wehewehe ʻana o ka hopena a me ka hoʻolaha ʻana i ka kānana.
2. Nā memo
Loaʻa i ka Polyacrylamide ka monomer acrylamide ʻawahia ʻole. I ka mālama ʻana i ka wai inu i hoʻopaʻa ʻia ma koʻu ʻāina, ʻo ka nui i ʻae ʻia he 0.01mg/L. I mea e pale ai i ka hōʻino ʻia o ka polyacrylamide, pono e hoʻomalu ʻia ka mahana mālama o kāna wai wai ʻaʻole e ʻoi aku ma mua o 40°C. I mea e pale ai i ka ʻike ʻana i ka lā, hiki ke hoʻohui ʻia kahi liʻiliʻi o ka mea hoʻopaʻa, e like me ka sodium thiocyanate, sodium nitrite, a pēlā aku, i ka wai. Pono e hoʻopaʻa ʻia ka pauka paʻa Polyacrylamide i loko o nā pahu hao i uhi ʻia me nā ʻeke polyethylene pale makū a i ʻole i uhi ʻia me nā papa polyethylene, a sila ʻia e pale ai i ka ʻike ʻana i ka makū kiʻekiʻe.
Pono e hoʻopili ʻia ka polyacrylamide wai a laila waiho ʻia i loko o nā pahu lāʻau a i ʻole nā pahu hao. ʻO ka manawa mālama ma kahi o 3 a 6 mau mahina. Pono e hoʻoulu ʻia ma mua o ka hoʻohana ʻana. ʻAʻole pono ke kiʻekiʻe o ka mahana mālama ma mua o 32°C a ʻoi aku ka haʻahaʻa ma mua o 0°C.
