30% Polyaluminum Chloride (PAC) no ka mālama ʻana i ka wai - Hoʻonui ʻia ka hana no nā ʻoihana like ʻole
Me ka hoʻomaikaʻi mau ʻana o nā kūlana mālama wai ʻoihana a me nā kūlana mālama wai ʻino o ke kūlanakauhale, ke ulu mau nei ke koi o ka mākeke no nā huahana polyaluminum chloride (PAC) kūpono a paʻa hoʻi.
Moʻolelo o nā Kipa ʻana o nā Mea Kūʻai: Kipa Hohonu o nā Mea Kūʻai Thai i AEFK
Ua like anei ʻo Ferric Sulfate me ka Polymeric Ferric Sulfate
He ʻakika a he alkaline paha ka polyaluminum chloride?
ʻO Polyaluminum Chloride (PAC) kahi polymer inorganic me kahi ʻano kemika koʻikoʻi o nā poly-nuclear hydroxyl complexes (form maʻamau: [Al₂(OH)ₙCl₆₋ₙ]ₘ). Ke hoʻoheheʻe ʻia i loko o ka wai, hana nā ion alumini (Al³⁺) i nā hopena hydrolysis, e hoʻokuʻu ana i nā ion hydrogen (H⁺) e hana i kahi hopena acidic me kahi waiwai pH i hoʻopaʻa ʻia ma waena o 2.0–4.5. Hāʻawi kēia ʻano iā PAC i nā pono aʻe.
ʻOkoʻa ma waena o Polyaluminum Ferric Chloride a me Polyaluminum Chloride
Nā kūlana no ka hoʻomau ʻana i ka hoʻohana ʻana ma hope o ka hōʻike ʻana i ka makū
Inā puʻupuʻu wale ka polyferric sulfate paʻa ma muli o ka makū, akā ʻaʻohe ʻōhū a hoʻololi paha i ke kala (e like me ka ʻole o ka melemele a ʻulaʻula paha), hiki nō ke hoʻohana maʻamau ma hope o ka wāwahi ʻana. I ka wā e hoʻohana ai, pono e hoʻoikaika i ka hui ʻana e paipai i ka hoʻoheheʻe ʻana a hoʻonui kūpono i ka nui o ka hopena e hōʻoia i ka hopena flocculation.
He aha nā mea e hiki ke hoʻohana ʻia e pani i ka polyaluminum chloride i ka mālama ʻana i ka wai ʻino?
I ka mālama ʻana i ka wai ʻino, hoʻohana pinepine ʻia ka polyaluminum chloride (PAC), akā hiki ke noʻonoʻo ʻia nā koho ʻē aʻe i nā kūlana kikoʻī (e like me ka hōʻemi ʻana i ke koena alumini, ka hoʻololi ʻana i ka maikaʻi o ka wai mahana haʻahaʻa a i ʻole ka hoʻonui ʻana i ke kumukūʻai):
ka hoʻohana ʻana o ka polyferric sulfate i ka mahiʻai aquaculture
Hoʻohana ʻia ka Polyferric sulfate (PFS) ma ke ʻano he mea hoʻomaikaʻi maikaʻi i ka maikaʻi o ka wai a me ka sediment i ka mahiʻai aquaculture. Hiki iā ia ke hoʻomaikaʻi nui i ke kaiapuni aquaculture ma o ka flocculation, precipitation, oxidation, decomposition a me ka nutrient supplementation. Eia nā noi kikoʻī:
