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 emi ana 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 e 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 ʻoiai i loko o ka palena i ʻae ʻia, ʻoi aku ka nui o ka hopena i ka helu hōʻole 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. Loaʻa ka hopena o ka pH i ke ʻano o nā haumia i loko o ka influent. No ka laʻana, no nā organics dissociable, emi 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 e 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 o 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 paʻakai paʻakai ke 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 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. ʻOi aku ka kiʻekiʻe o ka paʻakai o ka mea influent, 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 piʻi ʻana o ka ʻai paʻakai wai hānai e 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 hana mua e like me nā kānana one quartz, nā kānana palekana, a me nā mea ʻē aʻe. Inā hoʻohana ʻia 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 loa 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 mea 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 ka 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 e pale 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, ka kānana pololei, a me nā mea ʻē aʻe.
