He aha ka Polyaluminium Chloride?
ʻO ka polyaluminium chloride, i hoʻopau ʻia ʻo PAC, he mea mālama wai polymer inorganic. Hoʻokaʻawale ʻia nā ʻano i ʻelua ʻāpana: ka hoʻohana ʻana i ka wai inu home a me ka hoʻohana ʻana i ka wai inu ʻole i ka home, kēlā me kēia kumuhana i nā kūlana kūpono like ʻole. Hoʻokaʻawale ʻia ka hiʻohiʻona i ʻelua ʻano: wai a paʻa. Ma muli o nā ʻāpana like ʻole i loko o nā mea maka, aia nā ʻokoʻa i ka waihoʻoluʻu a me nā hopena noi.
ʻO ka polyaluminium chloride kahi paʻa ʻole a melemele paha. ʻO kona hoʻonā he wai ʻeleʻele ʻeleʻele a melemele paha, hiki ke hoʻoheheʻe ʻia i ka wai a hoʻoheheʻe i ka waiʻona, ʻaʻole hiki ke hoʻoheheʻe ʻia i ka waiʻona anhydrous a me ka glycerol. Pono e mālama ʻia i loko o kahi hale kūʻai ʻoluʻolu, ventilated, maloʻo a maʻemaʻe. I ka wā o ka lawe ʻana, pono e pale aku i ka ua a me ka lā pololei, pale i ka deliquescence, a mālama pono i ka wā o ka hoʻouka ʻana a me ka wehe ʻana e pale i ka pōʻino o ka pahu. ʻO ka manawa mālama no nā huahana wai he ʻeono mahina, a no nā huahana paʻa he hoʻokahi makahiki.
Hoʻohana nui ʻia nā mea hoʻomaʻemaʻe wai no ka hoʻomaʻemaʻe ʻana i ka wai inu, ka wai ʻona ʻenehana, a me ka wai hoʻoheheʻe kūloko o ke kūlanakauhale, e like me ka wehe ʻana i ka hao, fluorine, cadmium, radioactive pollution, a me ka aila lana. Hoʻohana ʻia ia no ka mālama ʻana i ka wai ʻino ʻoihana, e like me ka paʻi ʻana a me ke kala ʻana i ka wai ʻino. Hoʻohana ʻia ia i ka hoʻolei pololei ʻana, ka lāʻau lapaʻau, ka hana pepa, ka lāʻau, ka hana ʻili, ka ʻaila, ka ʻoihana kemika, a me nā kala. Hoʻohana ʻia ka polyaluminium chloride ma ke ʻano he mea mālama wai a me nā mea hoʻonaninani i ka mālama ʻana i ka ʻili.
Loaʻa ka polyaluminium chloride i ka adsorption, coagulation, precipitation a me nā waiwai ʻē aʻe. Loaʻa iā ia ke kūpaʻa maikaʻi ʻole, ka ʻawaʻawa, a me ka corrosiveness. Inā pāpaʻi wale ʻia ma ka ʻili, holoi koke me ka wai. Pono nā limahana hana e hoʻokomo i nā lole hana, nā maka, nā mīkina lima, a me nā kāmaʻa lōʻihi lōʻihi. Pono e hoʻopaʻa ʻia nā mea hana hana, a maikaʻi ka ventila o ka hale hana. ʻO ka polyaluminium chloride ka decomposes i ka wā i wela ai ma luna o 110 ℃, e hoʻokuʻu ana i ke kinoea hydrogen chloride, a hope loa e decomposes i ka alumini oxide; Hoʻopili me ka waika e hana i ka depolymerization, ka hopena i ka emi ʻana o ka polymerization degere a me ka alkalinity, a lilo i ka paʻakai alumini. Hiki i ka launa pū ʻana me ka alkali ke hoʻonui i ke kiʻekiʻe o ka polymerization a me ka alkalinity, i ka hopena i ka hoʻokumu ʻana i ka alumini hydroxide precipitate a i ʻole ka paʻakai aluminate; Ke hui pū ʻia me ka alumini sulfate a i ʻole nā paʻakai multivalent acid ʻē aʻe, hiki ke hana maʻalahi ka ua, hiki ke hōʻemi a nalowale paha i ka hana coagulation.
