Ka hoʻohana ʻana o ka Polyaluminum Chloride i ka mālama ʻana i ka wai inu

Polyaluminum chlorideHe flocculant ia a ʻo ia ka mea hoʻomaʻemaʻe wai i hoʻohana nui ʻia i ka mālama ʻana i ka wai inu. Hoʻohana nui kā mākou wai inu i ka wai mai ka Muliwai Melemele, ka Muliwai ʻo Yangtze a me nā waihona wai. Ma muli o ka nui o ka sediment a me ka nui o ka hana ʻana, pono ka polyaluminum chloride e hoʻolalelale i ka ua, a laila e hoʻomaikaʻi ana i ka pono o ka hana ʻana. ʻOiai he wai haʻahaʻa ka turbidity o ka wai mai nā hana wai, he kiʻekiʻe kona mau koi no ka hoʻomaʻemaʻe wai, no laila he paʻakikī no ka polyaluminum chloride maʻamau ke hoʻokō i nā kūlana mālama.

Ua ʻike mākou a pau he wai inu ka wai paipa o nā kānaka, a he mau lula akaka ko ka mokuʻāina a me nā koi kuhikuhi no ka mālama ʻana i ka wai inu. I kēia manawa, e hoʻomaopopo kākou i nā kūlana no ka mālama ʻana i ka wai inu a me nā koi no ka mālama ʻana i nā huahana wai inu.

No ke aha e pono ai i nā mea kanu wai ke hoʻohana i ka 30% alumini chloride?

ʻO ka 30%ʻO ka Polymeric Aluminum ChlorideUa hana ʻia mai ka pauka alumini hydroxide a me ka pauka calcium. Ke hoʻohālikelike ʻia me ka polyaluminum chloride ʻoihana maʻamau, ʻo 30% polyaluminum chloride nā ʻano o ka haʻahaʻa o ka metala kaumaha, ka emi ʻana o ka waiho ʻana, ka wai kemika maopopo a moakaka, a pēlā aku, a ua hoʻohana nui ʻia ma ke ʻano he lāʻau lapaʻau ma mua. Me ka hoʻomaikaʻi ʻana i nā koi o ka poʻe no ka maikaʻi o ka wai a me ka nānā ʻana i ke kaiapuni. ʻO kā mākou mau lāʻau lapaʻau e loaʻa ana he 30% polyaluminium chloride e hoʻokō pono i nā kūlana aupuni. No ka polyaluminum chloride, ʻokoʻa kāna kaʻina hana, nā mea maka a me nā hoʻohana.

ʻOiaʻiʻo, ʻo ka mea i hoʻohana pinepine ʻia he 28% polyaluminum chloride (PAC) no ka mālama ʻana i ka wai ʻino a me 30% polyaluminum chloride no ka mālama ʻana i ka wai inu. ʻOi aku ka maikaʻi o ka hopena o ka hoʻopili ʻana o 30% polyaluminum chloride. ʻOiai inā ʻike ʻia ka wai he moakāka, hiki nō i ka 30% polyaluminum chloride ke wehe i nā mea haumia. Pēlā nō hoʻi no ka mālama ʻana i ka wai ʻino maʻamau. Wahi a ka turbidity o ka wai ʻino, kūpono ka wai turbidity kiʻekiʻe no ka haʻahaʻa o ka polyaluminum chloride. ʻAʻole maʻemaʻe loa ka hoʻolei ʻana, akā haʻahaʻa ke kumukūʻai. Pono ka wai turbidity haʻahaʻa i ka mālama ʻana i ka maʻemaʻe!

ʻo Yuncangua kūpaʻa i ka hana ʻana a me ka hoʻolako ʻana i nā ʻoihana ʻoihananā kemika mālama wai, me ka manaʻo e hāʻawi i nā mea kūʻai aku me nā lawelawe kiʻekiʻe a me nā huahana kiʻekiʻe. Welina mai e kūʻai
