Hoʻohana i ka Reverse Osmosis Membrane a me nā ʻenehana pili i ka mālama wai
- Hoʻomaʻemaʻe wai ʻōpala
ʻO ka hoʻomaʻamaʻa wai ʻino kahi noi nui o nā membrane reverse osmosis. Ma o ka ʻenehana reverse osmosis, hiki ke mālama maikaʻi ʻia ka metala kaumaha a i ʻole ka ʻaila i loko o ka wai ʻino i hana ʻia e nā mea kanu mana a me nā hale paʻi a me ka wai. Hiki ke hoʻohana ʻia no ka mālama ʻana i ka ʻōpala o ke kūlanakauhale, ka ʻōpala leachate, etc.
I ke kaʻina hana o ka mana wela, hoʻohana ʻia ka nui o ka wai hoʻoluʻu e hoʻoheheʻe ʻia, ka mea maʻamau i loko o nā ʻano haumia a me ka turbidity kiʻekiʻe. Inā hoʻokuʻu pololei ʻia, e hoʻohaumia i ke kaiapuni. ʻO ka hui pū ʻana o nā mea hollow fiber ultrafiltration membrane a me ka polyamide composite reverse osmosis membrane hiki ke mālama i ka wai hoʻoluʻu i ka wai hoʻohana hou me ka turbidity wai ma lalo o 0.02 NTU a me ka helu pollution ma lalo o 0.7.
ʻO ka wai ʻino i hana ʻia e nā hale paʻi a me ka waihoʻoluʻu he nui nā ion paʻakai, nā ion kala, a me nā mea ʻē aʻe. ʻO ka hoʻohana ʻana i ka ultrafiltration a me ka reverse osmosis dual membrane ʻenehana hiki ke kānana i nā mea organik, nā ion paʻakai, a me nā mea ʻē aʻe i loko o ka wai ʻino, a ʻaʻole ʻoi aku ka kiʻekiʻe o ka hoʻohana ʻana i ka oxygen kemika o ka wai i hana ʻia ma mua o 10 mg/L, e hōʻike ana i kahi hopena mālama wai nui.
I loko o nā kaʻina hana hoʻomaʻemaʻe wai maʻamau i loaʻa nā metala kaumaha, pono e hoʻohui ʻia nā mea kemika, a kiʻekiʻe nā koi o ka hana lapaʻau. ʻO ka hoʻohana ʻana i nā membrane reverse osmosis a me nā ʻenehana reverse osmosis multi-stage no ka mālama ʻana i kēia wai ʻōpala hiki ke hoʻopau pono i nā mea metala kaumaha i loko o ka wai ʻino.
He nui a paʻakikī nā mea i loko o ka ʻōpala ʻōpala o ke kūlanakauhale. ʻO ka hoʻohana ʻana i ka polyamide reverse osmosis membrane no kāna mālama ʻana hiki ke hoʻomaʻemaʻe i ka leachate o ka ʻōpala i kahi pae hoʻokuʻu, e loaʻa ai ka mālama ʻana i ka leachate o ka ʻōpala.
- Hana wai maʻemaʻe
ʻO ka wai hoʻomaʻemaʻe ka nui o nā noi i ka wai inu home, ka hana ʻoihana, a me nā lāʻau lapaʻau. Loaʻa i kēia mau noi nā koi kiʻekiʻe no ka wai, a ʻo ka hoʻohana ʻana i nā membrane reverse osmosis no ka mālama wai e pono ai ka hoʻokō ʻana i nā kūlana hana pono.
Ma muli o ke kaʻina hana ʻoi loa o ka wai ultrapure, hiki ke hoʻohana ʻia nā ʻāpana membrane permeable i ka hana wai ultrapure. Hiki i ka ʻōnaehana reverse osmosis ke hoʻomalu i ka kahe wai a hiki i 650 m ³/h a hana i ka wai ultrapure me ka conductivity o 0.3 m S/cm. Hiki ke hoʻopau ʻia ka pilikia o ka hoʻoheheʻe ʻana o ka membrane i ka wā o ka mālama wai ma o nā hana hoʻomaʻemaʻe kemika. ʻO ka ʻōnaehana hoʻomaʻemaʻe wai maʻemaʻe i hoʻohana pinepine ʻia i kēia manawa ʻo ka ʻōnaehana electrodeionization reverse osmosis.
I ka ʻōlelo o ka hana wai ʻoihana, i mea e hoʻokō ai i ka noi no ka hoʻohana ʻana, ua noi nā mea noiʻi kūloko i kahi hopena e kūkulu i kahi ʻōnaehana reverse osmosis me ka hoʻohana ʻana i nā ʻāpana membrane composite ʻano ultra-low pressure roll type. ʻO ka hana wai membrane hoʻokahi o ka membrane permeable i kēia kumumanaʻo hiki ke hiki i ka 41.4 cubic mika i kēlā me kēia lā, me ka nui o ka mālama ʻana ʻaʻole i emi iho ma mua o 99.7%, hiki ke hoʻokō piha i ka koi wai o ka ʻoihana ʻoihana caustic soda.
Eia kekahi, i ka hana ʻana o ka ʻoihana chlor alkali, pono e kānana iā Ca ² ⁺ a me Mg ² ⁺ nā ion i loko o ka wai i ka wā hana. No laila, hiki ke hoʻohana ʻia ka PVD reverse osmosis membrane e wehe iā lākou, ʻoiai e hōʻoiaʻiʻo ana i kahi haʻahaʻa haʻahaʻa haʻahaʻa no ka sodium chloride, e hoʻokō ai i ka mālama wai a me ka hoʻomaʻemaʻe ʻana i ka hana ʻoihana chlor alkali.
I ka hana lāʻau lapaʻau, me ka hoʻohana ʻana i ka polyamide composite permeable membrane module ion separation system a me ka hoʻohana ʻana i kahi ʻano osmosis reverse osmosis ʻelua-pae e hana i ka wai maʻemaʻe i koi ʻia i ke kaʻina hana lāʻau lapaʻau hiki ke hoʻokō i nā hopena hana maikaʻi. Loaʻa i kēia papahana hoʻomaʻamaʻa wai ka helu hoʻihoʻi ʻaʻole i emi iho ma mua o 80% ma hope o ka lua o ka reverse osmosis, e lawe ana i nā pono waiwai nui i nā hui lāʻau.
