He hopena maikaʻi ka coagulant a me ka flocculant i ka wā e hoʻohana pū ʻia ai

In Mea hoʻohuihui (Polyaluminum Chloride, i ʻike nui ʻia ʻo ia ka mea hoʻomaʻemaʻe wai, i ʻike ʻia hoʻi ʻo polyaluminum chloride, polyaluminum no ka pōkole,PAC) a meMea hoʻoheheʻe wai (polyacrylamide, no ka polymer molekala kiʻekiʻe,PAM) Ma lalo o ka hana, ke hele nei ka mea i hoʻokuʻu ʻia i ka flocculation kino a me ka flocculation kemika, a laila e hana ana i nā flocs mea i hoʻokuʻu ʻia nui. Ma lalo o ka lana ʻana o ka hui pehu, lana nā "floccules" i ka ʻili wai e hana i ka scum, kahi i hoʻokaʻawale ʻia mai ka wai ma ka hoʻohana ʻana i kahi scraper slag. ʻAʻole e hoʻopilikia ka hoʻomaʻemaʻe ʻana i ka nozzle, a he kūpono ka hoʻohana ʻana i ka coagulant a me ka flocculant i ka mālama ʻana i ka wai ʻino.

ʻO ka Coagulant (polyaluminum chloride, i ʻike nui ʻia ʻo ka mea hoʻomaʻemaʻe wai, i ʻike ʻia hoʻi ʻo polyaluminum chloride, i kapa ʻia ʻo polyaluminum, PAC) hoʻohana nui ʻia no ka hoʻomaʻemaʻe ʻana i ka wai inu a me ka wai hoʻoneʻe ʻoihana, a me ka mālama ʻana i ka maikaʻi o ka wai kūikawā (e like me ka wai ʻaila, ka paʻi ʻana a me ka hoʻoluʻu ʻana i ka wai hana pepa, ka hoʻoheheʻe ʻana i ka wai, nā waiwai radioactive, nā metala kaumaha ʻawahia e like me Pb, Cr a me ka wai e loaʻa ana iā F, etc.), eia kekahi, hoʻohana nui ʻia i ka hoʻolei pololei ʻana, ka ʻeli ʻaila, ka ʻili, ka hana pepa metallurgical, etc., hoʻohana ʻia ka coagulant i ka wai I ka wā o ke kaʻina hana, hiki ke hoʻopaʻa ʻia a hōʻuluʻulu ʻia nā ʻāpana colloidal i loko o ka wai. ʻO ka maʻamau, ʻo ke kaʻina hana coagulation ka hoʻohui ʻana i nā kemika i ka wā o ke kaʻina hana mālama wai e hoʻoulu ai i nā haumia e coagulate, decolorize, wehe i nā mea paʻa i hoʻokuʻu ʻia, wehe i ka turbidity a me nā bacteria.

He hopena coagulation maikaʻi ko Polyaluminum ferric chloride. ʻO Polyaluminum ferric chloride (PAFC) kahi ʻano hou o ka flocculant composite inorganic cationic kiʻekiʻe. Loaʻa iā ia nā pono o ka ʻili ākea, ka hopena wehe turbidity maikaʻi, a me ka pala liʻiliʻi i nā pipeline lako; loaʻa iā ia nā ʻano o ka hoʻonohonoho flocculation flocculant paʻakai hao wikiwiki, ka hoʻokaʻawale maʻalahi, ka hana maikaʻi i ka mālama ʻana i ka wai mahana haʻahaʻa, a me ka laulā o ka waiwai PH i ka mālama ʻana i ka wai. I kēia manawa, ua hoʻohana pono ʻia ka polyaluminum ferric chloride i ka mālama ʻana i ka wai inu, ka wai ʻoihana a me nā wai ʻino ʻoihana like ʻole.

Mea hoʻohuihui (ʻo ka polyaluminum chloride, i ʻike nui ʻia ʻo ia ka mea hoʻomaʻemaʻe wai, i ʻike ʻia hoʻi ʻo polyaluminum chloride, i kapa ʻia ʻo polyaluminum, PAC) he ikaika ka decolorization a me ka decontamination, a ʻo ka hopena hoʻomaʻemaʻe wai he 4-6 mau manawa o AL2(SO4)3. 3-5 mau manawa ka nui o ALCL3, liʻiliʻi ka dosage, nui ka hopena, haʻahaʻa ke kumukūʻai, kiʻekiʻe ka pono, hiki ke hoʻololi i kahi ākea o ka waiwai pH, liʻiliʻi ka hōʻemi ʻana o ka waiwai pH o ka wai maka, no laila ʻaʻohe hopena corrosion i nā lako pipeline, ʻaʻohe pono e hoʻohui i nā mea hoʻohui ʻē aʻe, a hana koke nā flocs. Eia naʻe, he mānoanoa, he hana kiʻekiʻe, hiki ke piholo kiʻekiʻe, a me ka ua wikiwiki, no laila ʻike maopopo ʻia ka hopena hoʻomaʻemaʻe ma ka wai turbidity kiʻekiʻe.
