He mea hoʻomaʻemaʻe wai kiʻekiʻe ka Polyaluminum chloride, hiki ke hoʻomaʻemaʻe, hoʻohemo ʻala, hoʻohemo kala, a pēlā aku. Ma muli o kona mau ʻano koʻikoʻi a me nā pono a me ka laulā o ka hoʻohana ʻana, hiki ke hoʻemi ʻia ka nui ma mua o 30% i hoʻohālikelike ʻia me nā mea hoʻomaʻemaʻe wai kuʻuna, a hiki ke mālama ʻia ke kumukūʻai ma mua o 40%. Ua lilo ia i mea hoʻomaʻemaʻe wai maikaʻi loa i ʻike ʻia ma ka home a ma waho. Eia kekahi, hiki ke hoʻohana ʻia ka polyaluminum chloride e hoʻomaʻemaʻe i ka maikaʻi o ka wai kūikawā e like me ka wai inu a me ka lako wai piula, e like me ka wehe ʻana i ka hao, ka wehe ʻana i ka cadmium, ka wehe ʻana i ka fluorine, ka wehe ʻana i nā mea haumia radioactive, a me ka wehe ʻana i ka ʻaila palaki.
Nā hiʻohiʻona o ka PAC (Poly Aluminum Chloride):
Aia ka Polyaluminum chloride ma waena o ALCL3 a me ALNCL6-NLm] kahi e hōʻike ai ʻo m i ke kekelē o ka polymerization a hōʻike ʻo n i ke kekelē o ka neutrality o ka huahana PAC. ʻO ka Polyaluminum chloride i pōkole ʻia ʻo PAC ua kapa pinepine ʻia ʻo polyaluminum chloride a i ʻole coagulant, a pēlā aku. He melemele a melemele māmā paha ke kala, ʻeleʻele ʻeleʻele, hina hina ʻeleʻele resinous solid. Loaʻa i ka huahana nā waiwai adsorption bridging ikaika, a i ka wā o ke kaʻina hana hydrolysis, hana ʻia nā kaʻina hana kino a me ke kemika e like me ka coagulation, adsorption a me ka precipitation.
Ka Hoʻohana ʻana o ka PAC (Poly Aluminum Chloride):
Hoʻohana nui ʻia ka Polyaluminum chloride no ka hoʻolako wai kūlanakauhale a me ka hoʻomaʻemaʻe ʻana i ka wai: ka wai muliwai, ka wai waihona, ka wai honua; ka hoʻomaʻemaʻe wai ʻoihana, ka mālama ʻana i ka wai ʻino o ke kūlanakauhale, ka hoʻōla ʻana i nā mea pono i loko o ka wai ʻino o ka ʻoihana a me nā koena ʻōpala, e paipai ana i ka sedimentation o ka lanahu pulverized i ka wai ʻino holoi lanahu, ka hana ʻana o ka starch Recycling o ka starch; hiki i ka polyaluminum chloride ke hoʻomaʻemaʻe i nā wai ʻino o ka ʻoihana like ʻole, e like me: ka paʻi ʻana a me ka hoʻoluʻu ʻana i ka wai ʻino, ka wai ʻino ʻili, ka wai ʻino i loaʻa ka fluorine, ka wai ʻino metala kaumaha, ka wai ʻino i loaʻa ka aila, ka wai ʻino hana pepa, ka wai ʻino holoi lanahu, ka wai ʻino mining, ka wai ʻino hana pia, ka wai ʻino metallurgical, ka wai ʻino hana ʻiʻo, a pēlā aku; Polyaluminum chloride no ka mālama ʻana i ka wai ʻino: ka nui o ka pepa, ka hoʻomaʻemaʻe ʻana i ke kō, ka hoʻoheheʻe ʻana i ka hoʻoheheʻe ʻana, ka pale ʻana i ka wrinkle lole, ka mea lawe catalyst, ka hoʻomaʻemaʻe lāʻau lapaʻau i ka sima wikiwiki, nā mea maka cosmetic.
ʻO ka helu kuhikuhi maikaʻi o PAC (polyaluminum chloride)
He aha nā ʻōkuhi maikaʻi ʻekolu koʻikoʻi o ka PAC (polyaluminum chloride)? ʻO ka paʻakai, ka waiwai PH, a me ka ʻike alumina e hoʻoholo ai i ka maikaʻi o ka polyaluminum chloride nā ʻōkuhi maikaʻi ʻekolu koʻikoʻi o ka polyaluminum chloride.
1. Ka paʻakai.
ʻO ke kekelē o ka hydroxylation a i ʻole ka alkalization o kekahi ʻano ma PAC (polyaluminum chloride) ua kapa ʻia ʻo ke kekelē o ka basicity a i ʻole alkalinity. Hōʻike pinepine ʻia e ka lakio molar o ka alumini hydroxide B = [OH] / [Al] pakeneka. ʻO ka salinity kekahi o nā hōʻailona koʻikoʻi o ka polyaluminum chloride, pili loa i ka hopena flocculation. ʻO ke kiʻekiʻe o ka nui o ka wai maka a ʻo ke kiʻekiʻe o ka salinity, ʻoi aku ka maikaʻi o ka hopena flocculation. I ka hōʻuluʻulu ʻana, ma ka pae o ka turbidity wai maka o 86 ~ 10000mg / L, ʻo ka salinity kūpono o ka polyaluminum chloride he 409 ~ 853, a he nui nā ʻano ʻē aʻe o ka polyaluminum chloride e pili ana i ka salinity.
2. ka waiwai pH.
He mea nui nō hoʻi ka pH o ka hopena PAC (polyaluminum chloride). Hōʻike ia i ka nui o OH- i ke kūlana manuahi i loko o ka hopena. Hoʻonui pinepine ka waiwai pH o ka polyaluminum chloride me ka hoʻonui ʻia o ka basicity, akā no nā wai me nā ʻano like ʻole, ʻaʻohe pilina pili ma waena o ka waiwai pH a me ka basicity. He ʻokoʻa nā waiwai pH o nā wai me ka paʻakai like ke ʻokoʻa ka paʻakai.
3. Ka nui o ka alumina.
ʻO ka ʻike alumina i loko o ka PAC (polyaluminum chloride) he ana ia o nā ʻāpana kūpono o ka huahana, nona kahi pilina me ka nui o ka hopena. Ma ke ʻano laulā, ʻo ka nui o ka nui o ka pilina, ʻo ka kiʻekiʻe o ka ʻike alumina. Pili ka viscosity o ka polyaluminum chloride i ka ʻike alumina, a piʻi ka viscosity me ka piʻi ʻana o ka ʻike alumina. Ma lalo o nā kūlana like a me ka nui like o ka alumina, ʻoi aku ka haʻahaʻa o ka viscosity o ka polyaluminum chloride ma mua o ka alumini sulfate, ʻoi aku ka maikaʻi no ka lawe ʻana a me ka hoʻohana ʻana.
