Me ka wikiwiki o ka hoʻomohala ʻana i ka ʻoihana, ua hoʻonui ʻia ka hoʻokuʻu ʻana i ka wai ʻino i kēlā me kēia makahiki, e hoʻoweliweli ana i ke kaiapuni. I mea e pale ai i ke kaiaola, pono mākou e hana i nā hana kūpono e mālama i kēia wai ʻino. Ma ke ʻano hemea hoʻopaʻa kino, Ke lilo mālie nei ʻo PolyDADMAC i ka hopena i makemake ʻia no ka mālama ʻana i ka wai ʻōpala ʻoihana.
No ke aha e mālama ai i ka wai ʻino ʻoihana?
ʻAʻole hiki ke mālama ʻia nā pōʻino o ka wai ʻino ʻoihana. Loaʻa i ka wai ʻino ka nui o nā ion metala kaumaha, nā kemika ʻino, nā aila, a me nā mea ʻē aʻe. ʻO ka hoʻokuʻu ʻia ʻana o ka wai ʻino no ka wā lōʻihi e alakaʻi i ka haumia wai, ka pōʻino kaiaola, a me nā maʻi kanaka.
Me ka hoʻomau mau ʻana o ka hana ʻoihana, hoʻokuʻu pololei ʻia ka nui o ka wai ʻino i loko o ke kaiapuni me ka ʻole o ka mālama ʻana, e hōʻino nui ana i ke kaulike kaiaola a hoʻoweliweli i ke olakino kanaka. No laila, pono mākou e hana i nā hana e mālama i ka wai ʻino ʻoihana e hōʻemi i kona hopena maikaʻi ʻole i ke kaiapuni.
No ke aha e koho aiPolyDADMACe mālama i ka wai ʻino ʻoihana?
No ka hoʻoponopono ʻana i nā pōʻino o ka wai ʻino ʻoihana, hoʻohana ʻia nā ʻano lapaʻau maʻamau me ka dosing of alum a i ʻole PAC. Eia nō naʻe, loaʻa pinepine kēia mau ʻano kuʻuna i nā pilikia e like me ke kiʻekiʻe o ka sludge volume, nā hana paʻakikī, a me nā kumukūʻai kiʻekiʻe. No laila, pono mākou e ʻimi i kahi ʻano lapaʻau ʻoi aku ka maikaʻi, ʻoi aku ka maikaʻi, a me ke ʻano o ka mālama ʻana. Ma ke ʻano he coagulant organik, ua loaʻa i ka PolyDADMAC nā waiwai flocculation a me ka coagulation maikaʻi loa a hiki ke hoʻoneʻe koke i nā mea paʻa i hoʻokuʻu ʻia (maʻa mau i nā ion metala kaumaha a me nā kemika ʻino) i ka wai ʻino. Ke hoʻohālikelikeʻia me nāʻano hana hana maʻamau, ua loaʻa i ka PolyDADMAC nā mea maikaʻi o ka hana maʻalahi, ka hana hana kiʻekiʻe, ka liʻiliʻi liʻiliʻi, a me ka uku haʻahaʻa. Hoʻohana ʻia ʻo PolyDADMAC ma ke ʻano he mea hoʻoheheʻe sludge e hōʻemi i ka ʻike wai o ka sludge i hana ʻia e nā kaʻina hana ʻoihana ʻē aʻe.
Pehea e mālama ai ʻo PolyDADMAC i ka wai ʻōpala ʻoihana?
ʻO ka mea mua, e hoʻohui i ka wai i hoʻoheheʻe ʻia o PolyDADMAC i ka wai ʻino ma kekahi ʻāpana a hui pono me ka hoʻoulu ʻana. Ma lalo o ka hana a kahi coagulant, ʻo nā mea paʻa i hoʻopaʻa ʻia i loko o ka wai ʻōpala e hōʻuluʻulu koke e hana i nā flocs nui. A laila, ma o nā ʻanuʻu lapaʻau e like me ka sedimentation a i ʻole ka kānana, hoʻokaʻawale ʻia ka floc mai ka wai ʻino e hoʻokō i ke kumu o ka hoʻomaʻemaʻe ʻana i ka wai ʻino.
I ka hoʻohana ʻana i ka PolyDADMAC e mālama i ka wai ʻōpala ʻoihana, pono ʻoe e hoʻolohe i nā mea aʻe. ʻO ka mea mua, pono ʻoe e koho i kahi mea hoʻolako me ka maikaʻi hilinaʻi e hōʻoia i ka coagulant i kūʻai ʻia he ʻano kūpono. ʻO ka lua, e like me ke ʻano a me ka neʻe ʻana o ka wai ʻino, pono ke koho pono ʻia ke ʻano o ka coagulant e pale i ka overdosing a i ʻole ka lawa ʻole o ka mālama ʻana e hopena i nā hopena lapaʻau maikaʻi ʻole. I ka manawa like, pono e nānā mau ʻia ka maikaʻi o ka wai ʻino i mālama ʻia e hōʻoia i ka hoʻokō ʻana i nā kūlana hoʻokuʻu. Eia hou, pono e loaʻa i nā mea hoʻohana ka hoʻomaʻamaʻa ʻoihana a kamaʻāina i nā ʻano a me ka hoʻohana ʻana i nā coagulants a me ka mālama ʻana e hōʻoia i ka palekana a me ka paʻa o ke kaʻina hana.
I ka hōʻuluʻulu ʻana, ʻo PolyDADMAC, ma ke ʻano he coagulant organik maikaʻi a hoʻokele waiwai, loaʻa nā pōmaikaʻi nui i ka mālama ʻana i ka wai ʻōpala ʻoihana. Ma o ka hoʻohana pono ʻana o PolyDADMAC, hiki iā mākou ke hōʻemi maikaʻi i ka pōʻino o ka wai ʻino o ka ʻoihana i ke kaiapuni a pale i ke kaulike kaiaola a me ke olakino kanaka. I ka wā e hiki mai ana, me ka hoʻomau mau ʻana o ka ʻike kaiapuni a me ka holomua ʻenehana, e pāʻani ʻo PolyDADMAC i kahi hana koʻikoʻi ma ke kahua o ka mālama ʻana i ka wai ʻino.
