He aha ka Ferric Chloride i hoʻohana ʻia no ka mālama wai?

Ferric ChlorideHe hui kemika me ke kumu FeCl3. Hoʻohana nui ʻia ia i nā kaʻina mālama wai ma ke ʻano he coagulant ma muli o kona kūpono i ka wehe ʻana i nā haumia a me nā mea haumia mai ka wai a ʻoi aku ka maikaʻi o ka hana ma ka wai anuanu ma mua o ka alum. Ma kahi o 93% o ka ferric chloride e hoʻohana ʻia i ka mālama ʻana i ka wai, ʻo ia hoʻi ka wai ʻino, ka ʻōpala, ka wai kuke a me ka wai inu. Hoʻohana nui ʻia ka Ferric chloride ma ke ʻano paʻa e like me ka hopena no ka mālama ʻana i ka wai a me ka wai.

Ka hoʻohana ʻana i ka ferric chloride i ka mālama wai:

1. Coagulation a me Flocculation: ʻO kekahi o ka hoʻohana mua ʻana o ka ferric chloride i ka mālama ʻana i ka wai ma ke ʻano he coagulant. Ke hoʻohui ʻia i ka wai, hoʻopili ka ferric chloride me ka wai e hana i ka ferric hydroxide a hoʻopili ka mea hope i nā ʻāpana i hoʻokuʻu ʻia, nā mea olaola, a me nā mea haumia ʻē aʻe e hana ai i nā ʻāpana nui a kaumaha i kapa ʻia he flocs. Hiki i kēia mau flocs ke noho maʻalahi i ka wā o ka sedimentation a i ʻole ka kānana ʻana, e ʻae ai i ka wehe ʻana i nā haumia mai ka wai.

2. Hoʻopau Phosphorus: ʻO ka Ferric chloride ka mea maikaʻi loa i ka wehe ʻana i ka phosphorus mai ka wai. ʻO ka Phosphorus kahi meaʻai maʻamau i loaʻa i ka wai ʻino, a hiki i ka nui o nā pae ke alakaʻi i ka eutrophication i ka loaʻa ʻana o nā kino wai. Hoʻokumu ka Ferric chloride i nā paʻakikī hiki ʻole ke hoʻoheheʻe ʻia me ka phosphorus, a laila hiki ke hoʻoneʻe ʻia ma o ka ua a kānana paha, e kōkua ana e hōʻemi i nā pae phosphorus i ka wai.

3. Heavy Metal Wehe: Hoʻohana pū ʻia ka Ferric chloride e wehe i nā metala kaumaha, e like me arsenic, lead, a me ka mercury, mai ka wai. Hiki i kēia mau metala ke lilo i mea ʻawaʻawa a loaʻa i nā pōʻino koʻikoʻi i ke olakino inā aia i loko o ka wai inu. Hoʻokumu ka Ferric chloride i nā hydroxides metala ʻole a i ʻole metala oxychlorides, a laila hiki ke hoʻoneʻe ʻia ma o ka ua a i ʻole nā ​​kaʻina kānana, e hōʻemi pono i ka neʻe ʻana o nā metala kaumaha i ka wai.

4. Ke kala a me ka ʻala ʻala: He kūpono ka Ferric chloride i ka wehe ʻana i ka waihoʻoluʻu a me nā mea ʻala mai ka wai. Hoʻopaneʻe ia i nā pūhui organik e pili ana i ka waihoʻoluʻu a me ka ʻala, e wāwahi iā lākou i nā mea liʻiliʻi liʻiliʻi. Kōkua kēia kaʻina hana i ka hoʻomaikaʻi ʻana i ka maikaʻi maikaʻi o ka wai, i mea kūpono no ka inu ʻana, ʻoihana, a i ʻole nā ​​​​mea leʻaleʻa.

5. Hoʻoponopono pH: Ma ka mālama ʻana i ka pH, hiki i ka ferric chloride ke hoʻoikaika i ka hana o nā kaʻina hana lapaʻau ʻē aʻe, e like me ka coagulation, flocculation, a me ka disinfection. Hiki i ka pae pH kūpono ke kōkua i ka hana ʻana i nā kūlana kūpono no ka wehe ʻana i nā haumia a me nā mea haumia mai ka wai.

6. Hoʻoponopono ʻana i nā huahana disinfection: Hiki i ka Ferric chloride ke kōkua i ka mālama ʻana i ka hoʻokumu ʻana o nā disinfection byproducts (DBPs) i ka wā mālama wai. Ke hoʻohana pū ʻia me nā disinfectants e like me ka chlorine, hiki i ka ferric chloride ke hōʻemi i ka hoʻokumu ʻana o nā DBP e like me trihalomethanes (THMs) a me nā mea halocetic acid (HAAs), he mau carcinogens. Hoʻonui kēia i ka palekana a me ka maikaʻi o ka wai inu.

7. Hoʻoheheʻe wai: Hoʻohana pū ʻia ka Ferric chloride i nā kaʻina hoʻoheheʻe ʻana i ka wai ma nā mea kanu hoʻomaʻemaʻe wai. Kōkua ia i ka hoʻomaʻamaʻa ʻana i ka ʻōpala ma o ka hoʻoulu ʻana i ka hoʻokumu ʻana i nā flocs nui, ʻoi aku ka paʻakikī, e noho wikiwiki a hoʻokuʻu i ka wai. ʻO kēia ka hopena i ka hoʻomaikaʻi ʻana i ka hana dewatering a me ka hōʻemi ʻana i ka nui o ka lepo, e maʻalahi a ʻoi aku ka maikaʻi o ke kumukūʻai no ka mālama ʻana a me ka hoʻolei ʻana i ka ʻōpala.

He kuleana koʻikoʻi ʻo Ferric Chloride i nā ʻano like ʻole o ka mālama ʻana i ka wai, me ka coagulation, phosphorus a me ka wehe ʻana i ka metala kaumaha, ka waiho ʻana i ka waihoʻoluʻu a me ka ʻala, ka hoʻoponopono pH, ka disinfection byproduct control, a me ka sludge dewatering. ʻO kāna versatility a me ka maikaʻi e lilo ia i mea kemika waiwai i ka mālama ʻana i ka wai inu a me ka wai ʻino, e kōkua ana e hōʻoia i ka palekana, ka maikaʻi, a me ka hoʻomau o nā kumu wai.
