He aha nā flocculants cationic maʻamau?

He mea koʻikoʻi ka mālama ʻana i ka wai i ka hoʻokele kaiapuni, e hōʻoia i ka palekana o ka wai no ka ʻai ʻana a me ka hoʻohana ʻana i nā ʻoihana. ʻO kekahi o nā mea koʻikoʻi o kēia kaʻina hana, ʻo ia ka hoʻohana ʻana i nā flocculants - nā kemika e hoʻoikaika i ka hōʻuluʻulu ʻana o nā ʻāpana i hoʻopaneʻe ʻia i loko o nā pūʻulu nui, a i ʻole nā ​​flocs, a laila hiki ke maʻalahi ke wehe ʻia mai ka wai. Ma waena o nā ʻano flocculants like ʻole, ʻoi aku ka maikaʻi o nā flocculants cationic ma muli o kā lākou uku maikaʻi, e launa pū me nā ʻāpana ʻino i loaʻa maʻamau i ka wai ʻino. Ke ʻimi nei kēia ʻatikala i nā flocculants cationic maʻamau i hoʻohana ʻia i ka mālama wai a me kā lākou mau noi.

Nā Polyacrylamides Cationic(CPAM)

ʻO 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. Aia kēia mau polymers i nā subunits acrylamide, hiki ke hoʻopili ʻia e hoʻokomo i nā pūʻulu hana cationic. ʻO ka versatility o Cationic polyacrylamides aia i ko lākou kaumaha molecular adjustable a me ka nui o ka uku, e ʻae iā lākou e hana maʻamau no nā noi kikoʻī. ʻOi aku ka maikaʻi o nā C-PAM i ka mālama ʻana i ka wai ʻino o ka ʻoihana a me ka hoʻoheheʻe ʻana i ka lepo ma muli o ko lākou kiʻekiʻe o ka flocculation maikaʻi a me nā koi haʻahaʻa haʻahaʻa.

Poli(diallyldimethylammonium chloride) (PolyDADMAC)

ʻO PolyDADMAC kahi flocculant cationic i hoʻohana nui ʻia no kona kiʻekiʻe kiʻekiʻe a me ka pono i nā kaʻina mālama wai. He mea maikaʻi loa kēia polymer i nā kaʻina coagulation a me ka flocculation, e lilo ia i mea koho kaulana no ka mālama ʻana i ka wai inu, ka wai ʻino, a me nā effluent ʻoihana. Hana maikaʻi ʻo PolyDADMAC me nā flocculants a me nā coagulants ʻē aʻe, e hoʻonui ana i ke kaʻina hana lapaʻau holoʻokoʻa ma o ka hāʻawi ʻana i kahi mīkini paʻa no ka hōʻuluʻulu ʻana a me ka wehe ʻana.

Nā poliamina(PA)

ʻO nā polyamines kekahi ʻano o nā flocculants cationic i hoʻohana mau ʻia i ka mālama wai. ʻO kēia mau pūhui, ʻo ia hoʻi ka poly(dimethylamine-co-epichlorohydrin) a me nā hale like, e hōʻike ana i ka ikaika cationic charge density, e hana maikaʻi loa i ka hoʻokaʻawale ʻana i nā mea i hoʻopiʻi ʻia. Hoʻohana nui ʻia nā polyamines i ka hoʻomaʻamaʻa ʻana i ka wai maka, ka hoʻoneʻe ʻana i nā mea olaola, a me ka mālama ʻana i nā ʻano effluent ʻoihana. ʻO ko lākou hiki ke hana i nā flocs paʻa ka hopena i nā manawa hoʻoponopono wikiwiki a hoʻomaikaʻi i ka mālamalama o ka wai i mālama ʻia.

Nā noi a me nā pono

He kuleana koʻikoʻi nā cationic flocculants i ka nui o nā noi hoʻōla wai, mai ka wai ʻino a me ka hoʻomaʻemaʻe wai inu a hiki i ka hoʻokele waiwai ʻana i ka ʻoihana. ʻO kā lākou pōmaikaʻi nui e pili ana i ko lākou hiki ke hoʻokaʻawale maikaʻi i nā ʻāpana i hoʻopaʻa ʻole ʻia, e alakaʻi ana i ka hoʻokumu floc wikiwiki a maikaʻi. Loaʻa kēia i ka hoʻomaikaʻi ʻana i ka mālamalama, hoʻemi ʻia ka turbidity, a hoʻonui i ka maikaʻi o ka wai holoʻokoʻa. Hoʻohui ʻia, hoʻohana pinepine ʻia nā cationic flocculants i hui pū ʻia me nā kemika lapaʻau ʻē aʻe, e like me nā coagulants, e hoʻomaikaʻi i ke kaʻina hana a hoʻokō i nā kūlana wai i makemake ʻia.

ʻO ka hoʻohana ʻana i nā cationic flocculants he mea koʻikoʻi ia 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. ʻO nā polyacrylamides, polyamines, PolyDADMAC e hōʻike ana i kekahi o nā flocculants cationic maʻamau a maikaʻi loa i loaʻa i kēia lā. ʻO kā lākou versatility, kūpono, a me ka hoʻololi ʻana e lilo lākou i mau mea hana pono i ka hōʻoia ʻana i ka loaʻa ʻana o ka wai maʻemaʻe a palekana no nā hoʻohana like ʻole.

ʻOiaʻiʻo, pili pū ke koho ʻana i ka flocculant i ka maʻamau o ka hoʻohana ʻana o ka mea hoʻohana, ka haku ʻana i nā mea waiwai, ka ʻāina, a me nā mea ʻē aʻe.
