Loaʻa ka hopena maikaʻi o ka coagulant a me ka flocculant ke hoʻohana pū ʻia

In Coagulant (Polyaluminum Chloride, ʻike nui ʻia ʻo ka mea hoʻomaʻemaʻe wai, ʻike ʻia hoʻi he polyaluminum chloride, polyaluminum no ka pōkole,PAC) aFlocculant (polyacrylamide, pili i ka polymer molecular kiʻekiʻe,PAM) Ma lalo o ka hana, ka mea i hoʻokuʻu ʻia e hana i ka flocculation kino a me ka flocculation kemika, a laila e hana ai i nā flocs mea hoʻomaha nui. Ma lalo o ka buoyancy o ka pūʻulu huʻihuʻi, lana nā "floccules" i ka ʻili wai e hana i ka scum, i hoʻokaʻawale ʻia mai ka wai me ka hoʻohana ʻana i ka scraper slag. ʻO ka hoʻomaʻemaʻe ʻana i ka nozzle ʻaʻole ia e hoʻopili ʻia, a ʻoi aku ka maikaʻi o ka hoʻohana ʻana i ka coagulant a me ka flocculant i ka mālama ʻana i ka wai.

Hoʻohana nui ʻia ka coagulant (polyaluminum chloride, ka mea hoʻomaʻemaʻe wai, ʻike ʻia hoʻi he polyaluminum chloride, i kapa ʻia ʻo polyaluminum, PAC) no ka hoʻomaʻemaʻe ʻana i ka wai inu a me ka wai ʻona ʻoihana, a me ka mālama ʻana i ka maikaʻi o ka wai kūikawā (e like me ka ʻaila wai, ka paʻi ʻana a me ke kala ʻana i ka pepa hana wai, a me ka hoʻoheheʻe ʻana i nā metala kaumaha C. sege i loaʻa F, etc.), Eia kekahi, ua hoʻohana nui ʻia i ka hoʻolei pololei ʻana, ka ʻaila ʻaila, ka ʻili, ka hana pepa metallurgical, a me nā mea ʻē aʻe, hoʻohana ʻia ka coagulant i ka wai I ka wā o ke kaʻina hana, hiki ke hoʻopaʻa ʻia nā ʻāpana colloidal i ka wai a hui pū ʻia. ʻO ka maʻamau, ʻo ke kaʻina coagulation e hoʻohui i nā kemika i ka wā o ka mālama ʻana i ka wai e hana i nā haumia e coagulate, decolorize, wehe i nā mea paʻa i hoʻokuʻu ʻia, wehe i ka turbidity a me ka bacteria.

He hopena coagulation maikaʻi ka polyaluminum ferric chloride. ʻO ka polyaluminum ferric chloride (PAFC) he ʻano hou o ka flocculant composite cationic inorganic kiʻekiʻe. Loaʻa iā ia nā pōmaikaʻi o ka ākea ākea, ka hopena hoʻohemo turbidity maikaʻi, a me ka corrosion liʻiliʻi i nā pipelines; loaʻa nō hoʻi nā hiʻohiʻona o ka paʻakai paʻakai paʻakai paʻakai paʻakai paʻakai flocculation, maʻalahi ka hoʻokaʻawale ʻana, hana maikaʻi i ka mālama wai haʻahaʻa haʻahaʻa, a me ka laulā o ka waiwai PH i ka mālama wai. I kēia manawa, ua hoʻohana maikaʻi ʻia ka polyaluminum ferric chloride i ka mālama ʻana i ka wai inu, ka wai ʻenehana a me nā ʻano wai ʻona ʻenehana.

Coagulant (polyaluminum chloride, i ʻike nui ʻia he mea hoʻomaʻemaʻe wai, ʻike ʻia hoʻi he polyaluminum chloride, i kapa ʻia ʻo polyaluminum, PAC) he ikaika decolorization a me ka decontamination hiki, a ʻo ka hopena hoʻomaʻemaʻe wai he 4-6 mau manawa o AL2 (SO4)3. 3-5 mau manawa ka nui o ka ALCL3, liʻiliʻi ka dosage, nui ka hopena, haʻahaʻa ke kumukūʻai, kiʻekiʻe ka pōmaikaʻi, hiki ke hoʻololi i kahi ākea o ka waiwai pH, ka liʻiliʻi o ka waiwai pH o ka wai maka liʻiliʻi, no laila ʻaʻohe hopena corrosion i nā mea pipeline, ʻaʻohe pono e hoʻohui i nā mea hoʻohui ʻē aʻe, a ua puka koke ka flocs. maopopo loa.
