Pehea e hana ai ka Poly Aluminum Chloride?

I ka honua o ka mālama wai,Poly Aluminum Chloride(PAC) ua puka mai ma ke ʻano he coagulant maʻalahi a maikaʻi. Me kona hoʻohana nui ʻana i ka hoʻomaʻemaʻe ʻana i ka wai inu a me nā mea kanu hoʻomaʻemaʻe wai, ke hana nei ʻo PAC i nā nalu no kona hiki ke hoʻomaʻemaʻe i ka wai a wehe i nā mea haumia. Ma kēia ʻatikala, ʻimi mākou i ka hana a PAC a me kona koʻikoʻi i ke kahua o ka mālama wai.

Ke Kemika Ma hope o PAC:

ʻO ka Poly Aluminum Chloride he hui kemika i haku ʻia me ka aluminika a me ka chlorine, me ke ʻano AlnCl(3n-m)(OH)m. Loaʻa kona ʻano maʻalahi mai ka hiki ke noho i nā ʻano like ʻole e pili ana i ka ratio alumini-a-chloride a me ke degere o ka polymerization. ʻAe kēia mau ʻokoʻa i ka PAC e hoʻololi i kahi ākea o nā pilikia mālama wai.

Coagulation a me ka Flocculation:

ʻO ka hana nui o ka PAC i ka mālama wai ʻo ka coagulation a me ka flocculation. Ke hoʻohui ʻia ka PAC i ka wai maka, e hana ʻia ka hydrolysis. I loko o kēia kaʻina hana, hana ia i nā alumini hydroxide flocs, kahi mea maikaʻi loa i ka hopu ʻana i nā haumia i hoʻokuʻu ʻia i ka wai. Ke hana nei ka alumini hydroxide flocs e like me nā magnet liʻiliʻi, e huki ana a hoʻopaʻa pū i nā ʻāpana e like me ka lepo, bacteria, a me nā mea kūlohelohe.

Wehe i nā mea haumia:

ʻO ka hana coagulation-flocculation o PAC e kōkua i ka wehe ʻana i nā mea haumia like ʻole mai ka wai, me nā mea paʻa i hoʻopaʻa ʻia, colloids, a me kekahi mau mea i hoʻoheheʻe ʻia. Ke ulu nui a kaumaha nā floc, noho lākou i lalo o ka pahu lapaʻau ma o ka sedimentation a i ʻole e paʻa maʻalahi ʻia e nā kānana. ʻO kēia ka hopena i ka hana ʻana i ka wai maʻemaʻe a maʻemaʻe.

ʻAʻohe pH:

ʻO kekahi o nā pōmaikaʻi koʻikoʻi o ka PAC ʻo kona pH neutrality. ʻAʻole like me nā coagulants kuʻuna e like me ka alumini sulfate a i ʻole ka ferric chloride, hiki ke hoʻololi nui i ka pH o ka wai, mālama ʻo PAC i nā pae pH paʻa. Hoʻemi kēia i ka pono o nā kemika hou e hoʻoponopono i ka pH, maʻalahi i ke kaʻina hana a me ka hōʻemi ʻana i nā kumukūʻai.

Nā pōmaikaʻi o ka hoʻohana ʻana iā PAC:

Pono: Hana maikaʻi ʻo PAC ma kahi ākea ākea o nā ʻano wai a me nā ʻūhā.

Versatility: Hiki ke hoʻohana ʻia no ka mālama ʻana i ka wai mua a me ke kula kiʻekiʻe.

ʻO nā koena haʻahaʻa: Hoʻohua ka PAC i nā mea liʻiliʻi liʻiliʻi, e hōʻemi ana i nā kumukūʻai hoʻokuʻu.

Kūʻai-Effective: ʻO kona kūpono a me ka pH neutrality e lilo ia i koho kūpono no nā mea kanu mālama wai.

Palekana: ʻOi aku ka palekana o ka PAC ma mua o kekahi mau coagulants.

Nā noi o PAC:

Loaʻa ka PAC i ka hoʻohana nui ʻana i nā ʻoihana like ʻole, me ka mālama ʻana i ka wai kūloko, ka mālama ʻana i ka wai ʻino ʻoihana, a me nā ʻoihana pepa a me nā lole lole. ʻO kona hiki ke wehe i ka nui o nā mea haumia e lilo ia i mea waiwai nui no ka hōʻoia ʻana i nā lako wai maʻemaʻe a palekana.

I ka hopena, ʻo ka Poly Aluminum Chloride (PAC) kahi hopena hoʻōla wai kupaianaha e hana ana ma o ka coagulation a me ka flocculation. ʻO kona kūpono, versatility, a me ka pH neutrality ua hoʻonoho iā ia ma ke ʻano he koho maikaʻi loa no nā hale mālama wai ma ka honua holoʻokoʻa. Ke hoʻomau nei ka koi ʻana i ka wai maʻemaʻe, ke hoʻomau nei ʻo PAC i mea pāʻani koʻikoʻi i ka hōʻoia ʻana i ke komo ʻana i ka wai palekana a me ka wai inu no nā kaiāulu a puni ka honua.
