He aha nā flocculants cationic maʻamau?

He ʻāpana koʻikoʻi ka mālama ʻana i ka wai o ka hoʻokele kaiapuni, e hōʻoia ana i ka palekana o ka wai no ka inu ʻana a me ka hoʻohana ʻana i nā ʻoihana. ʻO kekahi o nā mea nui i kēia kaʻina hana, ʻo ia ka hoʻohana ʻana i nā flocculants—nā kemika e paipai ana i ka hōʻuluʻulu ʻana o nā ʻāpana i hoʻokuʻu ʻia i loko o nā hui nui aʻe, a i ʻole nā ​​flocs, a laila hiki ke wehe maʻalahi ʻia mai ka wai. Ma waena o nā ʻano flocculants like ʻole, he kūpono loa nā flocculants cationic ma muli o kā lākou uku maikaʻi, kahi e launa pū ai me nā ʻāpana i hoʻopiʻi maikaʻi ʻole ʻia i loaʻa pinepine i ka wai hoʻoneoneo. Ke nānā nei kēia ʻatikala i nā flocculants cationic maʻamau i hoʻohana ʻia i ka mālama ʻana i ka wai a me kā lākou noi.

Nā Polyacrylamides Cationic(CPAM)

ʻO nā Cationic Polyacrylamides, kekahi o nā flocculants i hoʻohana nui ʻia i ka ʻoihana mālama wai. No nā mea hoʻohana he nui, ʻo CPAM kā lākou koho maikaʻi loa. Loaʻa i kēia mau polymers nā subunits acrylamide, hiki ke hoʻopilikino ʻia e hoʻokomo i nā hui hana cationic. Aia ka versatility o nā Cationic polyacrylamides i ko lākou kaumaha molekala hiki ke hoʻololi ʻia a me ka density charge, e ʻae ana iā lākou e hoʻopilikino ʻia no nā noi kikoʻī. He kūpono loa nā C-PAM i ka mālama ʻana i ka wai hoʻoneʻe ʻoihana a me ka sludge dewatering ma muli o kā lākou pono flocculation kiʻekiʻe a me nā koi dosage haʻahaʻa.

Poly(diallyldimethylammonium chloride) (ʻO PolyDADMAC)

He flocculant cationic i hoʻohana nui ʻia ʻo PolyDADMAC i ʻike ʻia no kona kiʻekiʻe o ka hoʻouka ʻana a me ka pono i nā kaʻina hana mālama wai. He kūpono loa kēia polymer i nā kaʻina hana coagulation a me flocculation, e lilo ia i koho kaulana no ka mālama ʻana i ka wai inu, ka wai hoʻoneoneo, a me nā effluents ʻoihana. Hana maikaʻi ʻo PolyDADMAC me nā flocculants a me nā coagulants ʻē aʻe, e hoʻomaikaʻi ana i ke kaʻina hana mālama holoʻokoʻa ma ka hāʻawi ʻana i kahi ʻano hana ikaika no ka hōʻuluʻulu ʻana a me ka wehe ʻana i nā ʻāpana.

Nā Polyamines(PA)

ʻO nā Polyamines kekahi ʻano o nā flocculants cationic i hoʻohana pinepine ʻia i ka mālama ʻana i ka wai. ʻO kēia mau hui, e komo pū ana me ka poly (dimethylamine-co-epichlorohydrin) a me nā ʻano like, hōʻike i ka nui o ka hoʻouka cationic ikaika, e hoʻolilo ana iā lākou i mea kūpono loa i ka hoʻopau ʻana i nā ʻāpana i hoʻopiʻi maikaʻi ʻole ʻia. He mea pono loa nā Polyamines i ka hoʻomaʻemaʻe ʻana i ka wai maka, ka wehe ʻana i nā mea olaola, a me ka mālama ʻana i nā ʻano wai hoʻoheheʻe ʻoihana like ʻole. ʻO ko lākou hiki ke hana i nā flocs paʻa e hopena i nā manawa hoʻonoho wikiwiki a me ka hoʻomaikaʻi ʻana i ka maopopo o ka wai i mālama ʻia.

Nā noi a me nā pono

He kuleana koʻikoʻi ko nā flocculants cationic i nā ʻano hana mālama wai like ʻole, mai ka wai hoʻoheheʻe kūlanakauhale a me ka hoʻomaʻemaʻe wai inu a hiki i ka hoʻokele wai ʻoihana. ʻO ko lākou pono nui, aia ko lākou hiki ke hoʻopau pono i nā ʻāpana i hoʻopiʻi maikaʻi ʻole ʻia, e alakaʻi ana i ka hoʻokumu ʻana o ka floc wikiwiki a me ka maikaʻi. ʻO kēia ka hopena i ka hoʻomaikaʻi ʻana i ka maopopo, ka hoʻemi ʻana i ka turbidity, a me ka hoʻomaikaʻi ʻana i ka maikaʻi o ka wai holoʻokoʻa. Eia kekahi, hoʻohana pinepine ʻia nā flocculants cationic me nā kemika mālama ʻē aʻe, e like me nā coagulants, e hoʻomaikaʻi i ke kaʻina hana mālama a hoʻokō i nā kūlana maikaʻi o ka wai i makemake ʻia.

He mea koʻikoʻi ka hoʻohana ʻana i nā flocculants cationic i nā kaʻina hana mālama wai hou, e hāʻawi ana i nā hopena kūpono a hilinaʻi hoʻi no ka hōʻuluʻulu ʻana a me ka wehe ʻana i nā ʻāpana. ʻO Polyacrylamides, polyamines, PolyDADMAC kekahi o nā flocculants cationic maʻamau a maikaʻi loa i loaʻa i kēia lā. ʻO ko lākou versatility, ka pono, a me ka hiki ke hoʻololi iā lākou he mau mea hana pono loa ia no ka hōʻoia ʻana i ka loaʻa ʻana o ka wai maʻemaʻe a palekana no nā hoʻohana like ʻole.

ʻOiaʻiʻo, ʻo ke koho ʻana o ka flocculant e pili ana hoʻi i nā ʻano hoʻohana a ka mea hoʻohana, ka haku mele ʻana o nā mea, ke kaiapuni, a me nā mea ʻē aʻe. Pono e hahai ʻia ke alakaʻi hoʻohana huahana.
