He "Mea Kaua Kilokilo" no ka Hana ʻAna i nā Wai ʻOle: PolyDADMAC

I ka hana ʻoihana a me ke ola o kēlā me kēia lā, ke koʻikoʻi nei ka pilikia o ka wai ʻino. Hoʻohana nui ʻia ʻo PolyDADMAC no ka hoʻomaʻemaʻe ʻana i ka wai ʻino o ka ʻoihana a me ka wai o luna. Hoʻopili ʻia ia no ka mālama ʻana i ka wai ʻino mai ka hana ʻana i nā minerala, ka wai ʻino hana pepa, ka wai ʻino ʻaila mai nā kahua aila a me nā hale hoʻomaʻemaʻe, a me ka wai ʻino o ke kūlanakauhale. Hoʻohana ʻia ʻo PolyDADMAC ma ke ʻano heflocculant no ka mālama ʻana i ka wai piula wai.

He aha ka PolyDADMAC?

ʻO PolyDADMACHe polymer cationic ia, a ʻo kona ʻano he wai viscous melemele ʻole a palupalu. ʻO kona ʻano molekala kū hoʻokahi e hāʻawi iā ia me nā waiwai flocculation a me adsorption ikaika, e hiki ai iā ia ke hui koke me nā ʻāpana i hoʻopiʻi maikaʻi ʻole ʻia, nā colloids a me nā mea ʻē aʻe i loko o ka wai.

Ka Hoʻōla ʻana i ka Wai ʻŌpala

Hoʻohana ʻia ʻo PolyDADMAC i ka mālama ʻana i ka wai ʻōpala ma ke ʻano he coagulant organik mua e hoʻopau i nā mea colloidal i hoʻopiʻi maikaʻi ʻole ʻia a hoʻemi i ka nui o ka sludge i hoʻohālikelike ʻia me nā coagulants inorganic. Hoʻohana ʻia ʻo PolyDADMAC ma ke ʻano he coagulant i ka hoʻomaʻemaʻe wai. He kūpono ia i ka coagulating a me ka flocculating i nā ʻāpana inorganic a me nā organik e like me ka silt, clay, algae, bacteria a me nā virus. I nā kiʻekiʻe kiʻekiʻe, hiki i ka polymer organik ke wehe i nā mea organik kūlohelohe e like me nā humic a me nā fulvic acids e hopena ana i ka liʻiliʻi o nā precursors byproduct disinfection a me ka emi ʻana o ke kala.

Ka Hana ʻAna i ka Wai ʻOle

Ma ke kahua o ka mālama ʻana i ka wai ʻino, hana kupaianaha ʻo PolyDADMAC. I ka mālama ʻana i ka wai ʻino hana pepa, hiki iā ia ke hoʻokahe pono i nā mea i hoʻokuʻu ʻia e like me nā olonā a me nā mea hoʻopihapiha, e hoʻomālamalama koke ai i ka wai ʻino. I ka mālama ʻana i ka paʻi ʻana a me ka hoʻoluʻu ʻana i ka wai ʻino, hiki iā ia ke hui pū me nā molekole dye, uhaʻi i kā lākou chromophores, a wehe pono i ke kala, a laila e hoʻomaʻalahi ai i ka mālama ʻana i ka paʻi ʻana a me ka hoʻoluʻu ʻana i ka wai ʻino. Eia kekahi, i hoʻohālikelike ʻia me nā flocculants kuʻuna, pono ia i kahi dosage liʻiliʻi akā loaʻa nā hopena maikaʻi aʻe, hiki ke hōʻemi nui i ke kumukūʻai mālama.

ʻImi ʻAila

Ma waho aʻe o ka mālama ʻana i ka wai ʻino, i ka unuhi ʻana i ka ʻaila, hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻohui no nā wai ʻeli e hoʻomaikaʻi i ke kūpaʻa o nā wai ʻeli a me ko lākou hiki ke lawe i ke one, e hōʻoiaʻiʻo ana i ka holomua mālie o ka unuhi ʻana.

ʻOihana Hana Pepa

I loko o ka ʻoihana hana pepa, hiki iā ia ke hoʻonui i ka ikaika o ka pepa a hoʻomaikaʻi i ke kūkulu ʻia ʻana o ka pepa. Hoʻohana ʻia ʻo PolyDADMAC no ka kaohi ʻana i nā mea hoʻonāukiuki i ke kaʻina hana pepa. Hāʻawi ia i ka hoʻopaʻa maikaʻi ʻana o ka pitch mai ka pulp mechanical a me ka latex mai ka haki i uhi ʻia. Hoʻohana ʻia i ka holo pōkole o kahi wili pepa e hoʻoikaika i ka paʻa ʻana a me ka hoʻohemo ʻana i ka wai. Eia kekahi, hiki ke hoʻohana ʻia e hoʻomaikaʻi i ka pono o nā kānana disk a me nā flotators, a no ka cationization o nā mea hoʻopihapiha e hāʻawi i ka paʻa ʻana o ka mea hoʻopihapiha nui loa.

ʻOihana lole

I ka ʻoihana lole, hiki ke hoʻohana ʻia no ka hoʻopau ʻana i nā lole antistatic, no laila e hoʻomaikaʻi ai i ka maikaʻi o nā lole.

Loaʻa i kā mākou huahana ke kūlana paʻa. Ma hope o ka nānā pono ʻana, ua hōʻea kāna mau ʻōkuhi āpau i ka pae alakaʻi i ka ʻoihana. Loaʻa iā mākou kahi hui o nā loea loea a me kahi kahawai hoʻolako paʻa. Hiki iā mākou ke paipai i nā hiʻohiʻona huahana kūpono e like me kāu mau hiʻohiʻona hoʻohana kikoʻī.
