He aha nā hōʻailona nui e nānā ai i ke kūʻai ʻana i ka Polyaluminum Chloride?

I ke kuai anaPolyaluminum Chloride(PAC), he coagulant i hoʻohana nui ʻia i nā kaʻina hana hoʻōla wai, pono e loiloi ʻia kekahi mau hōʻailona koʻikoʻi e hōʻoia i ka hoʻokō ʻana o ka huahana i nā kūlana i koi ʻia a kūpono i kāna noi i manaʻo ʻia. Aia ma lalo nā hōʻailona nui e nānā ai:

1. Aluminum maʻiʻo

ʻO ka mea hana mua i ka PAC he alumini. ʻO ka maikaʻi o ka PAC ma ke ʻano he coagulant e hilinaʻi nui ʻia i ka neʻe ʻana o ka alumini. ʻO ka maʻamau, ua hōʻike ʻia ka ʻike alumini ma PAC ma ke ʻano he pākēneka o Al2O3. Loaʻa ka PAC kiʻekiʻe ma waena o 28% a 30% Al2O3. Pono e lawa ka waihona alumini e hōʻoia i ka coagulation maikaʻi me ka hoʻohana nui ʻole, hiki ke alakaʻi i ka pono ʻole o ka hoʻokele waiwai a me nā hopena maikaʻi ʻole i ka maikaʻi o ka wai.

2. Ke kumu

ʻO ka Basicity kahi ana o ka degere o ka hydrolysis o nā ʻano alumini ma PAC a ua hōʻike ʻia ma ke ʻano he pākēneka. Hōʻike ia i ka ratio o ka hydroxide i nā ion alumini i loko o ka hopena. ʻO ka PAC me ka laulā maʻamau o 40% a 90% ka mea maʻamau i makemake ʻia no nā noi mālama wai. ʻO ke kumu kiʻekiʻe e hōʻike pinepine ana i ka coagulation ʻoi aku ka maikaʻi akā pono e kaulike ʻia me nā koi kikoʻī o ke kaʻina hoʻomaʻemaʻe wai e pale aku ai i ka mālama ʻana a i ʻole ka mālama ʻana.

4. Nā pae haumia

ʻO ka loaʻa ʻana o nā mea haumia e like me nā metala kaumaha (e laʻa, ke kēpau, cadmium) pono e liʻiliʻi. Hiki i kēia mau haumia ke hoʻopilikia i ke olakino a pili i ka hana o PAC. Loaʻa i ka PAC maʻemaʻe kiʻekiʻe nā pae haʻahaʻa loa o ia mau mea haumia. Pono nā pepa kikoʻī i hāʻawi ʻia e nā mea hana e hoʻokomo i ka ʻike e pili ana i ka nui o ka ʻae ʻia o kēia mau haumia.

6. Ke ʻano (paʻa a i ʻole ka wai)

PACloaʻa ma nā ʻano paʻa (pada a granules) a me nā ʻano wai. ʻO ke koho ʻana ma waena o nā ʻano paʻa a me nā ʻano wai e pili ana i nā koi kikoʻī o ka lāʻau lapaʻau, me nā hale mālama, nā lako dosing, a me ka maʻalahi o ka lawelawe ʻana. Makemake pinepine ʻia ʻo Liquid PAC no ka maʻalahi o ka hoʻohana ʻana a me ka hemo wikiwiki ʻana, akā hiki ke koho ʻia ka PAC paʻa no ka mālama lōʻihi a me nā pono o ka halihali. Eia naʻe, pōkole ke ola o ka wai, no laila ʻaʻole pono e kūʻai pololei i ka wai no ka mālama ʻana. Manaʻo ʻia e kūʻai i ka paʻa a hana iā ʻoe iho e like me ka ratio.

7. Ola a me ka Paʻa

ʻO ke kūpaʻa o ka PAC i ka manawa e pili ana i kāna hana. Pono ka PAC kūlana kiʻekiʻe i ke ola paʻa, e mālama ana i kona mau waiwai a me ka pono no nā manawa lōʻihi. ʻO nā kūlana mālama, e like me ka mahana a me ka ʻike ʻana i ka ea, hiki ke hoʻopili i ka paʻa, no laila pono e mālama ʻia ka PAC ma kahi maloʻo a maloʻo i loko o nā pahu i hoʻopaʻa ʻia e mālama i kona maikaʻi.

8. Uku-pono

Ma waho aʻe o ka maikaʻi o ka huahana, pono nō hoʻi e noʻonoʻo i ka maikaʻi o ke kumukūʻai o ke kūʻai. E hoʻohālikelike i nā kumukūʻai, ka ʻeke, ka lawe ʻana, a me nā mea ʻē aʻe o nā mea hoʻolako like ʻole e ʻimi i nā huahana me ke kumu kūʻai kūpono.

I ka hōʻuluʻulu ʻana, i ke kūʻai ʻana i ka polyaluminum chloride, pono e noʻonoʻo i ka ʻike alumini, ka waiwai, ka waiwai pH, nā pae haumia, solubility, form, shelf life, cost-effectiveness, and regulatory compliance. Hoʻoholo pū kēia mau hōʻailona i ke kūpono a me ka pono o ka PAC no nā noi hoʻōla wai like ʻole.
