Pehea ka hana ʻana o ka Poly Aluminum Chloride?

I ke ao o ka mālama ʻana i ka wai,Poly Aluminum Chloride(PAC) ua kū mai ma ke ʻano he mea hoʻohuihui kūpono a maikaʻi hoʻi. Me kona hoʻohana nui ʻia ʻana i ka hoʻomaʻemaʻe ʻana i ka wai inu a me nā hale hana hoʻomaʻemaʻe wai ʻino, ke hana nei ʻo PAC i nā nalu no kona hiki kupaianaha ke hoʻomaʻemaʻe i ka wai a wehe i nā mea haumia. Ma kēia ʻatikala, e ʻeli mākou i ka hana a PAC a me kona koʻikoʻi ma ke kahua o ka hoʻomaʻemaʻe wai.

ʻO ke Kemika ma hope o PAC:

He hui kemika ʻo Poly Aluminium Chloride i haku ʻia me ka alumini a me ka chlorine, me ke ʻano AlnCl(3n-m)(OH)m. ʻO kona ʻano maʻalahi e pili ana i ka hiki ke loaʻa i nā ʻano like ʻole ma muli o ka lakio alumini-a-chloride a me ke kekelē o ka polymerization. ʻAe kēia mau ʻano like ʻole i ka PAC e hoʻololi i nā pilikia mālama wai like ʻole.

Coagulation a me Flocculation:

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

Ka Wehe ʻana i nā Mea Haumia:

Kōkua ke ʻano hana coagulation-flocculation o PAC i ka wehe ʻana i nā ʻano haumia like ʻole mai ka wai, me nā mea paʻa i hoʻokuʻu ʻia, nā colloids, a me kekahi mau mea i hoʻoheheʻe ʻia. Ke ulu nui a kaumaha nā flocs, noho lākou i lalo o ka pahu mālama ma o ka sedimentation a i ʻole e paʻa maʻalahi ʻia e nā kānana. ʻO ka hopena o ka hana ʻana o ka wai maopopo a maʻemaʻe.

pH Kūlike ʻole:

ʻO kekahi o nā pono koʻikoʻi o PAC ʻo ia kona pH neutrality. ʻAʻole e like me nā coagulants kuʻuna e like me ka alumini sulfate a i ʻole ferric chloride, hiki ke hoʻololi nui i ka pH o ka wai, mālama ʻo PAC i nā pae pH i paʻa. Hoʻemi kēia i ka pono no nā kemika hou e hoʻoponopono i ka pH, e hoʻomaʻalahi ana i ke kaʻina hana a hoʻemi i nā kumukūʻai.

Nā Pōmaikaʻi o ka Hoʻohana ʻana i ka PAC:

Ka Pono: Hana pono ka PAC ma nā ʻano like ʻole o ka wai a me nā turbidities.

Ka Hoʻohana like ʻana: Hiki ke hoʻohana ʻia no ka mālama ʻana i ka wai mua a me ke kolu.

Nā Koena Haʻahaʻa: Hoʻopuka ka PAC i nā huahana sludge liʻiliʻi, e hōʻemi ana i nā kumukūʻai hoʻolei.

Kūʻai Kūpono: ʻO kona pono a me ka pH neutrality e lilo ia i koho kūpono no nā hale hana mālama wai.

Palekana: ʻOi aku ka palekana o ka lawelawe ʻana i ka PAC ma mua o kekahi mau mea hoʻohuihui ʻē aʻe.

Nā noi o ka PAC:

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

I ka hopena, ʻo Poly Aluminium Chloride (PAC) kahi hopena mālama wai kupaianaha e hana ana ma o ka coagulation a me ka flocculation. ʻO kona pono, ka versatility, a me ka pH neutrality ua hoʻonoho iā ia ma ke ʻano he koho makemake ʻia no nā hale mālama wai ma ka honua holoʻokoʻa. Ke hoʻomau nei ka ulu ʻana o ke koi no ka wai maʻemaʻe, ʻo PAC ke kumu nui i ka hōʻoia ʻana i ke komo ʻana i ka wai palekana a inu no nā kaiāulu a puni ka honua.
