Aluminum Sulfate: He Coagulant ikaika i ka hoʻomaʻemaʻe wai

Coagulationa ʻo ka flocculation nā pōhaku kihi o ka mālama ʻana i ka wai i ka ʻimi ʻana i ka wai maʻemaʻe. ʻO kēia kaʻina hana ikaika e alakaʻi ʻia e nā waiwai maikaʻi o ka alumini sulfate, ka mea e hoʻololi ai i ka wai turbid, wai haumia i kumu aniani.

ʻO ka alumini sulfate, i kapa pinepine ʻia ʻo alum, ʻo ia ka hero unsung of water treatment. He paʻakai ia me ke ʻano molekiko Al2(SO4)3. Hiki ke hoʻoheheʻe ʻia i ka wai a hoʻohana nui ʻia ma ke ʻano he coagulant i ka hoʻomaʻemaʻe wai inu a me nā mea kanu hoʻomaʻemaʻe wai, a me ka hana pepa.

Pehea ka hana alum i loko o ka wai ʻauʻau

Aluminum sulfate hydrolyzes e hana i nā ʻano paʻakikī i hoʻopaʻa maikaʻi ʻia i loko o ka wai, a ua hoʻopiʻi maikaʻi ʻia nā mea ʻāpana i loko o ka hopena. I loko o nā hola he nui, ua huki nā ʻano alum i nā ʻāpana i hoʻokuʻu ʻia a hoʻemi i ka nui o ka uku o nā mea i hoʻokuʻu ʻia, no laila, hiki ke hui ʻia kēia mau ʻāpana i ka floc nui a kaumaha a hiki i ka lohi ʻana i lalo o ka wai. ʻOi aku ka maikaʻi me ka wai ʻauʻau kaulike a me ka mahana o ka wai ma kahi o 70 degere centigrade.

Pehea e hoʻohana ai i ka alum ma ke ʻano heCoagulant i loko o nā loko ʻauʻau

1. ʻO nā ʻauʻau ʻauʻau, nā ʻōpala a me nā pulupulu e wehe i nā ʻōpala nui.

2. E kaulike i ka wai pH, ka alkalinity, ka paakiki calcium, ka chlorine manuahi a me ka waikawa cyanuric e ko makou mau papa hoao.

3. ʻO ka mea maʻamau o ka alumini sulfate i hoʻohana ʻia e like me ka flocculant i nā loko ʻauʻau he 20-50 mg / L. Ma hope o ka hoʻopaʻa ʻana, pono e mālama ʻia ka loko wai no 2-8 mau hola, a laila e hoʻopau ʻia ka paila a waiho ʻia e kū no 12-24 mau hola. Inā ʻaʻole i loaʻa ka hopena, e hana hou i ke kaʻina hana.

4. E kau i ka pahu porous i ka recirculation, e holo i ka pamu no 2 mau hola a e holoi i ka loko.

5. E ho'opau i ka pauma no 12-24 mau hola a hiki i ka pae 'ana o ka alum i lalo o ka wai.

6. E kau i ka pahu orifice ma luna o ka ʻōpala a me ka ʻōpala i hoʻopaʻa ʻia i ka alum i loko o ka ʻōpala.

Hiki ke hoʻohana ʻia ka alumini sulfate ma nā wahi ʻē aʻe, a e wehewehe pōkole mākou ma lalo nei.

Nā lole i kāhiko ʻia

ʻO kekahi o nā mea hoʻohana no ka alumini sulfate ʻo ke kala a paʻi ʻana ma ka lole. Ke hoʻoheheʻe ʻia i loko o ka wai nui me kahi pH kūʻokoʻa a i ʻole ka liʻiliʻi alkaline, hana ka pūhui i kahi slime i kapa ʻia ʻo alumini hydroxide. Kōkua kēia mucilage i ka wai e hoʻopili ai i nā lole lole ma o ka hiki ʻole o ka wai o ka wai. ʻO ka alumini sulfate ka mea e hana ai ma ke ʻano he "fixative," ʻo ia hoʻi ka mea e hoʻopaʻa ai i ke ʻano molekala o ka wai a me ka lole i ʻole e holo ka wai i ka wā i pulu ka lole.

Pepa

Hoʻohana ʻia ka alumini sulfate i ka hana pepa. Kōkua ka Aluminum sulfate i ka nui o ka pepa. Ma kēia kaʻina hana, hui pū ia me ka kopa rosin e hoʻololi i ka hoʻopaʻa ʻana o ka pepa, a pēlā kona ʻano ʻīnika. Hoʻopuka ka Aluminum sulfate i nā kūlana ʻawaʻawa, aʻo nā mea hoʻopaʻa nui synthetic e hana i ka pepa ʻakika ʻole ʻaʻole hiki ke pala.

Noi Lapaau

He nui nā hoʻohana kūpono o ka Aluminum sulfate i ka lāʻau lapaʻau. Hoʻohana nui ʻia ia ma ke ʻano he coagulant no nā ʻoki liʻiliʻi a me nā abrasions a ma ke ʻano he deodorant (ma muli o kāna mau mea antimicrobial). Hoʻopili pū ka pūhui a hoʻopaʻa i nā antigens protein i loko o ka hopena, a ʻo ka hopena e hoʻonui ai i ka immunogenicity o ka maʻi ma o ka hoʻomaʻamaʻa ʻana i ka hoʻokuʻu lohi ʻana o nā antigens mai nā waihona kano i hoʻokumu ʻia ma ke kahua o ka inoculation. Eia kekahi, ua hoʻohana ʻia nā mea hoʻonā e loaʻa ana i ka 5% a i ka 10% e like me nā noi topical no nā maʻi maʻi a me ka pale ʻana i nā mea huna ʻala mai nā ʻili mucous. Aia ka Aluminum sulfate i nā mea i hoʻohana ʻia i ka ʻoihana lāʻau. No ka laʻana, hoʻohana ʻia ia i ka hoʻomākaukau ʻana i nā kulu pepeiao alumini acetate.
