ʻO ka paʻakai hōʻole i ka paʻakai: Ua hoʻoholo ʻia ka desalination rate o ka RO membrane element i ka manawa o kāna hana ʻana, a ʻo ka desalination rate e pili ana i ka nui o ka ultra-thin desalination layer ma ka ʻili o ka RO membrane element, ʻo ka denser ka desalination layer, ʻoi aku ka kiʻekiʻe o ka desalination rate, a me ka haʻahaʻa o ka hana wai. ʻO ka desalination rate o RO membrane no nā mea like ʻole e hoʻoholo nui ʻia e ke ʻano a me ke kaumaha molekala o ka waiwai, ʻo ka desalination rate o nā ion kiʻekiʻe-valent a me nā ion monovalent paʻakikī hiki ke ʻoi aku ma mua o 99%, a me ka desalination rate o nā ion monovalent e like me nā sodium ions, potassium ions, a me ka chloride ions he haʻahaʻa haʻahaʻa, akā hiki ke hoʻohana ʻia ma mua o 98% o ka membrane. desalination rate of RO membrane) ʻO ka neʻe ʻana o ka mea olaola me ke kaumaha molekala i ʻoi aku ma mua o 100 hiki ke ʻoi aku ma mua o 98%, akā ʻoi aku ka haʻahaʻa o ka neʻe ʻana o nā mea organik me ke kaumaha molekala ma lalo o 100.

Ke ʻano helu helu o ka paʻakai hōʻole ʻana a me ka paʻakai paʻakai o ka RO membrane:

ʻO ka paʻakai paʻakai o ka RO membrane = RO membrane permeate concentration/influnt water concentration ×100%

Ka helu desalination o ka membrane RO = (ka maʻiʻo paʻakai o ka wai permeate / maʻiʻo paʻakai o ka wai ikaika o ka membrane 1-RO) ×100%

Hana ʻia ka wai: GPD = Galani (US)/La, GFD = Galani (US)/ka wāwae pāhāhā/lā

ʻO ka wai o ka membrane RO - pili i ka hiki ke hoʻohua wai o ka ʻōnaehana RO, ʻo ia hoʻi, ka nui o ka wai e hele ana ma ka membrane RO i kēlā me kēia ʻāpana o ka manawa, i hōʻike pinepine ʻia i nā tone i ka hola a i ʻole nā ​​galani i kēlā me kēia lā. 1 galani (US) = 3.785 lita, 1 mika cubic = 264.2 galani (US).

ʻO ka permeability o ka membrane RO kekahi mea hōʻailona koʻikoʻi o ka hua wai o ka mea membrane RO. E pili ana i ka kahe kahe o ka permeate no kēlā me kēia ʻāpana membrane, i hōʻike pinepine ʻia ma nā galani no kēlā me kēia kapuaʻi square i kēlā me kēia lā (GFD). ʻO ka nui o ke kahe osmotic e alakaʻi i kahi kahe wai wikiwiki e kū pono ana i ka ʻili o ka membrane RO, kahi e hoʻonui ai i ka hoʻoheheʻe ʻana o ka membrane.

ʻO ke kaomi (ke kaomi hana maikaʻi loa): 1 kg kaomi = 1 bar ≈ 14.5 psi = poʻo 10m (pump)

PSI (Pounds per square inch) he ʻāpana o ke ana. P pili i ka paona, S pili i ka huinahalike, I pili i na iniha, a ua hoohanaia o Amerika Huipuia e hoohana i ka psi ma ke ano he hui, oia hoi ka paona-ikaika no ka iniha huinaha.
