Hana ʻia i ka wai ʻino ʻoihana – Flocculants (PAM)

I loko o ka wai ʻōpala ʻoihana, aia kekahi mau mea haumia e hoʻopololei i ka wai, kahi e paʻakikī ai kēia mau wai ʻino e hoʻomaʻemaʻe.Pono e hoʻohana i kahi flocculant e hoʻomaʻemaʻe i ka wai e hoʻokō i ke kūlana hoʻokuʻu.No kēia flocculant, paipai mākoupolyacrylamide (PAM).

Flocculantno ka hana ʻana i ka wai ʻino

ʻO ka polyacrylamide kahi polymer hiki ke hoʻoheheʻe wai.Aia i loko o kāna kaulahao molekala nā pūʻulu polar, hiki ke hoʻopili i nā ʻāpana i hoʻokuʻu ʻia i ka hopena a hoʻohui i nā ʻāpana e hana i nā flocs nui aʻe.Hiki i nā flocs nui i hoʻokumu ʻia ke hoʻolalelale i ka ua o nā ʻāpana i hoʻokuʻu ʻia a hoʻolalelale i ka hopena o ka wehewehe ʻana.Hoʻohālikelike ʻia me ka mālama wai ʻino maʻamau, paʻakikī loa ka mālama ʻana i ka wai ʻino.I ke kaʻina hana o ka mālama ʻana i ka wai ʻino kemika, pono nā ʻano mea like ʻole e like me flocculants, coagulants, a me nā decolorizers.I waena o lākou, ʻo ka flocculant maʻamau i hoʻohana ʻia he polyacrylamide nonionic.

ʻO ka ulu ʻana o ka polyacrylamide

1. Aia i loko o ke kaulahao molekila polyacrylamide nā pūʻulu polar, hiki ke komo i nā ʻāpana i hoʻokuʻu ʻia i ka wai a me ke alahaka ma waena o nā ʻāpana e hana i nā flocs nui aʻe.

2. Hiki i ka polyacrylamide non-ionic ke hoʻoikaika i ka ua o nā ʻāpana i hoʻokuʻu ʻia ma o ka hana ʻana i nā flocs nui, a laila e hoʻolōʻihi i ka wehewehe ʻana o ka hopena a hoʻolaha i ka hopena filtration.

3. Ma waena o nā huahana flocculant a pau, he hopena maikaʻi ka polyacrylamide non-ionic i ka mālama ʻana i ka wai ʻawaʻawa, a ʻo ka wai ʻōpala kemika maʻamau.No laila, loaʻa i ka polyacrylamide non-ionic kona mau pono kūʻokoʻa ihoʻomaʻemaʻe wai kino.

4. Hiki ke hoʻohanaʻia ka coagulant i hui pū me nā paʻakai inorganic e like me polyaluminum, polyiron a me nā flocculants inorganic'ē aʻe, aʻoi aku ka maikaʻi o ka hopena.Ma muli o nā hiʻohiʻona o ka polyacrylamide non-ionic i loaʻa iā ia nā pōmaikaʻi i ka mālama ʻana i ka wai ʻōpala.

Hāʻawi mākou i ka PAM kiʻekiʻe no ka hoʻolako mua ʻana o ka hale hana, i hiki iā ʻoe ke kiʻi i ka PAM kūpono a me ka ʻike ma hope o ke kūʻai aku.
