ʻO ka poʻe i loaʻa ka ʻike nui i ka mālama ʻana i ka wai hoʻomaʻemaʻe ʻana, ʻike lākoupdadmache flocculant me ke kūpaʻa i ʻoi aku ma mua o nā mea hana maʻamau. ʻO ka hapa nui o nā flocculants ma ka mākeke he palupalu loa, hiki ke hōʻino ʻia mai ka lā, nā mahana haʻahaʻa, a me nā waikawa/alkalis, maʻalahi ka hui ʻana a lilo i mea pono ʻole ma hope o ka hapalua mahina o ka mālama ʻana, a hāʻule koke i ka wā e hoʻokomo ʻia ai i loko o ka wai hoʻoneoneo paʻakikī. Eia naʻe, hōʻike ʻo Polydimethyldiallyl ammonium chloride i ke ahonui kiʻekiʻe loa. ʻAʻole i hoʻopilikia ʻia kona pono e nā mahana kiʻekiʻe i ke kauwela a i ʻole nā mahana hau i ka hoʻoilo, e lilo ia i mea hilinaʻi "paʻa" i ka mālama ʻana i ka wai hoʻoneoneo.
ʻO kēia kūpaʻa kiʻekiʻe loa mai kona ʻano molekala kū hoʻokahi a paʻa. Ua like ke kinona molekala o kēia mea hana me ke kaulahao kaula hemp mānoanoa a paʻa, me kahi ʻano paʻa a ʻaneʻane ʻaʻohe wahi nāwaliwali. I ka hoʻohālikelike ʻana, ʻo ka hapa nui o nā flocculants maʻamau he mau molekala liʻiliʻi palupalu e wāwahi maʻalahi a palaho i nā wahi wela kiʻekiʻe, acidic, a alkaline paha, e nalowale loa ana ko lākou hopena flocculation. I ka hoʻohālikelike ʻana, hōʻike ka polydimethyldiallyl ammonium chloride i ke kūpaʻa kaulahao molekala kiʻekiʻe loa ma hope o ka polymerization. ʻOiai ma lalo o ka hoʻolaha lōʻihi ʻana i nā wahi wai hoʻoneoneo wela kiʻekiʻe, e mau ana kona ʻano molekala a maikaʻi. ʻO kēia ke kumu nui e hiki ai iā ia ke hoʻopili koke i nā haumia wai hoʻoneoneo a hana i nā flocs mānoanoa ʻoiai ma lalo o ka mālama ʻana i ka ea ākea a me nā kūlana wela kiʻekiʻe.
ʻO nā hui i hoʻopuehu like ʻia ma kona kaulahao molekala e hana ma ke ʻano he pale pale kūlohelohe, e hāʻawi ana i ka mea hana i ka hoʻohālikelike maikaʻi loa o ka wai. ʻAʻole i loaʻa i nā flocculants maʻamau ka pale ʻili a ua maʻalahi ke uhi ʻia e ka ʻaila a me nā haumia i loko o ka wai hoʻoneoneo, e nalowale ana ko lākou hiki ke adsorption. Eia nō naʻe, ʻaʻole wale nā hui i hoʻopuehu maikaʻi ʻia o kēia mea hana e hana ma ke ʻano he mau pahuhopu adsorption no nā haumia liʻiliʻi, nā pigments, a me nā mea haumia akā hoʻokaʻawale pū iā ia mai nā mea hoʻopilikia o waho e like me nā waikawa, alkalis, nā kemika ʻē aʻe, a me ka ʻaila, e pale ana i ke ʻano molekala kumu mai ka hōʻino. ʻAe kēia i ka hoʻohālikelike paʻa me ka wai hoʻoneoneo ʻoihana paʻakikī mai ka hoʻoluʻu ʻana, ka paʻi ʻana, a me nā ʻoihana kemika, kahi i koʻikoʻi ai nā loli pH.
Ma ke ʻano o ka mālama ʻana a me ka lawe ʻana, ʻoi aku ka maikaʻi o kona mau pono ma mua o nā mea like. ʻO ka hapa nui o nā flocculants pauka he mea maʻalahi loa ia i ka omo ʻana o ka wai a me ka hui ʻana; ʻoiai nā pae haʻahaʻa iki i ka wā o ka mālama ʻana e hōʻino iā lākou, lilo i mea pono ʻole, a hiki ʻole ke hoʻoheheʻe. Hōʻike ʻo Polydimethyl diallyl ammonium chloride (PDMC) i ke kūpaʻa kūikawā i nā ʻano wai a me nā ʻano paʻa, ʻaʻohe hōʻike ʻana i nā hopena kemika intermolecular pono ʻole. Hiki i nā hale hana mālama wai ʻōpala ke hōʻiliʻili iā ia i ka nui me ka ʻole o ka koi ʻana i ka mahana a i ʻole ka kaohi maʻamau. Hiki ke mālama ʻia i loko o nā hale waihona mahana ambient no nā manawa lōʻihi a hiki ke hoʻohana maʻamau ʻoiai ma hope o ka hoʻopaʻa ʻana a me ka hoʻoheheʻe ʻana ma waho i ka hoʻoilo, me ka ʻaneʻane ʻole o nā pilikia o ka hōʻino a i ʻole ka hāʻule ʻana, e hōʻemi nui ana i ke kumukūʻai o ka flocculant.
Eia kekahi, hōʻike kāna huahana flocculated i ke kūpaʻa kupaianaha. Hoʻopuka nā flocculants maʻamau i nā flocs palupalu a palupalu e maʻalahi ke wāwahi me ke kahe iki o ka wai, e alakaʻi ana i ka hoʻi ʻana o nā mea haumia i ka wai a me ka hāʻule ʻana o ka mālama ʻana. I ka hoʻohālikelike ʻana, loaʻa i ka PDMC nā hiki adsorption a me nā entanglement ikaika loa, e hoʻopaʻa pono ana i nā haumia maikaʻi a me ka aila e hana i nā flocs mānoanoa a paʻa. Hōʻike kēia mau flocs i ke kūpaʻa ikaika i ka ʻino ʻana o ke kahe ʻana o ka wai, nā waiwai hoʻonohonoho maikaʻi loa, a hana i nā puʻupuʻu sludge compact hiki ke kaomi pololei ʻia a hoʻoheheʻe ʻia, kūpono loa no nā hiʻohiʻona mālama wai ʻino paʻakikī e like me nā kahua aila. Me kona kūpaʻa piha, ua lilo kēia mea i flocculant makemake lōʻihi i ka ʻoihana mālama wai ʻino.
