ʻAʻole i hana ka membrane RO hou?

No ke aha i hana ʻole ai ka membrane RO hou?E kamaʻilio e pili ana i nā kumu a me nā hoʻonā ma lalo nei:

1. He haʻahaʻa loa ka wela o ka wai inlet:
ʻO ka mahana hana maʻamau o ka membrane reverse osmosis he 25 ℃, a e hoʻemi ka hana wai e 3% i kēlā me kēia manawa e hāʻule ka mahana i hoʻokahi degere.Inā haʻahaʻa ka mahana ma mua o 0°C, maloʻo ka wai maka a ʻaʻole hiki ke hana i ka wai maʻamau.

2. Haʻahaʻa loa ke kaomi wai inlet:
ʻO ke kumu hana o ka reverse osmosis membrane ka kānana ma ke kaomi.Inā lōʻihi ka hoʻohana ʻana o ka paila booster, hāʻule ke kaomi inlet, a ʻaʻole hiki i ka wai maka ke hoʻokō i nā koi, ʻaʻohe wai i waho o ka ʻōnaehana reverse osmosis.ʻO ka maʻamau, pono ke kaomi hana o ka membrane reverse osmosis e hiki i 4.14MPA.

3. Hoʻoikaika pH
Loaʻa i nā modula RO membrane like ʻole ka pae pH ʻae ʻia, a ʻaʻohe hopena o ka pH o ka wai influent i ka hana tater.Akā i loko o ka laulā i ʻae ʻia, ʻoi aku ka hopena o ka paʻakai paʻakai.Ma kekahi ʻaoʻao, loaʻa i ka waiwai pH kekahi hopena i ka conductivity o ka wai huahana.ʻO kēia no ka mea ʻo ka reverse osmosis membrane ponoʻī ka hapa nui o kekahi mau pūʻulu ikaika, a hiki i ka waiwai pH ke hoʻopilikia i ka membrane.ʻO ke kahua uila ma ka ʻili e pili ana i ka neʻe ʻana o nā ion.He hopena pololei ka pH waiwai i ke ʻano o nā haumia i loko o ka influent.No ka laʻana, no nā mea kūlohelohe dissociable, e emi ana ka helu hōʻole me ka emi ʻana o ka pH.Ma ka ʻaoʻao ʻē aʻe, no ka mea, ʻo ka CO2 i hoʻoheheʻe ʻia i loko o ka wai e hoʻopilikia nui ʻia e ka waiwai pH, i ka wā i haʻahaʻa ai ka waiwai pH, aia ia ma ke ʻano o ke kinoea CO2 a komo maʻalahi i ka membrane osmosis reverse.No laila, ʻoi aku ka haʻahaʻa o ka hōʻole ʻana i ka paʻakai ke haʻahaʻa ka pH waiwai.I ka piʻi ʻana o ka pH, ua hoʻololi ʻia ke kinoea CO2 No ka HCO-3 a me CO2-3 ion, ke piʻi mālie nei ka paʻakai paʻakai, a hiki i ka nui o ka paʻakai i ka kiʻekiʻe ma waena o pH 7.5 a me 8.5.

4. Hoʻoikaika i ka paʻakai
ʻO ke kaomi Osmotic kahi hana o ka paʻakai a i ʻole ka mea ola i loko o ka wai.ʻO ke kiʻekiʻe o ka paʻakai, piʻi ka osmotic pressure.Ke hoʻomau ʻia ke kaomi inlet, e emi ka ʻupena ʻupena a e emi ka hana wai.Hoʻohālikelike ka paʻakai paʻakai i ka ʻokoʻa o ka paʻakai ma waena o ka mua a me ke kua o ka membrane.ʻO ke kiʻekiʻe o ka paʻakai maʻiʻo o ka mana, ʻoi aku ka nui o ka ʻokoʻa ʻokoʻa, a piʻi ka paʻakai permeability, e alakaʻi ana i ka emi ʻana o ka paʻakai.No ka ʻōnaehana like, ʻokoʻa ka ʻike paʻakai wai hānai, ʻokoʻa ke kaomi hana a me ka conductivity wai huahana.No kēlā me kēia hoʻonui ʻana o ka wai hānai paʻakai ma 100 ppm, pono e hoʻonui ʻia ke kaomi wai inlet ma kahi o 0.007 MPa.I ka manawa like, ma muli o ka piʻi ʻana o ka hoʻonui ʻana, ua hoʻonui ʻia ka conductivity wai huahana.

5. Hoʻopaʻa mua ʻia:
He kiʻekiʻe nā koi o nā membrane osmosis reverse no ka lawe ʻana i ka wai, a hoʻohui pinepine ʻia nā mea pono pretreatment, e like me nā kānana one quartz, nā kānana palekana, a me nā mea ʻē aʻe.Inā hoʻohana ʻia ia no ka manawa lōʻihi, hiki ke ālai ʻia ka hāmeʻa pretreatment ma muli o ka nui o nā haumia.Ma hope o ka hoʻopaʻa ʻana, aia kahi hāʻule o ka hana wai.Ke hoʻopaʻa ʻia nā mea haumia pretreatment, ʻaʻole hiki i ka wai maka ke komo i ka membrane reverse osmosis ma o ka pretreatment, a laila e ʻike ʻia ka osmosis hoʻohuli.

6. Ua ālai 'ia ka valve check:
I ka wā o ka hoʻohana ʻana, hiki ke ālai ʻia ka valve check e nā haumia.Hiki iā ʻoe ke lawe i ka valve check e nānā inā ua piʻi nui ka hana wai o ka ʻōnaehana.ʻO ka maʻamau, liʻiliʻi ka manawa o ka paʻa ʻana o ka valve check.

7. Hoʻopaʻa ʻia ka membrane reverse osmosis e nā haumia.
Ma waho aʻe o ka hoʻomaʻamaʻa mua ʻana, hiki ke hoʻopaʻa ʻia nā membrane reverse osmosis.Loaʻa i ka wai maka ka nui o nā haumia.ʻO ka maʻamau, hiki i ka mea hoʻomaʻamaʻa mua ke kānana i ka hapa nui o nā haumia e hoʻokō i ka wai influent i nā koi maʻamau o ka reverse osmosis.Eia nō naʻe, ua hoʻolālā ʻia kekahi mau ʻōnaehana hoʻomaʻamaʻa mua ʻole, e hopena i nā haumia e like me nā mea olaola, chlorine manuahi, a me nā paʻa paʻa.I loko o ka mea membrane, e hoʻopaʻa ana i ka mea membrane.Ke paʻa loa nā haumia i ka nui o ka pore membrane, ʻaʻohe hana wai.

8. Ua ālai ʻia ka ʻōnaehana kānana hope:
I ke kaʻina o ka hoʻohana ʻana, hoʻohui pinepine ʻia nā mea pale kūpono ma hope o ka membrane reverse osmosis no ka pale ʻana i ka wai o ka huahana mai ka hoʻopili ʻia ʻana e nā kumu ʻē aʻe, e like me ka kānana kalapona i hana ʻia, kānana pololei, a me nā mea ʻē aʻe. pili pū i ka reverse osmosis o ka hana wai o ka ʻōnaehana.
