He hopena paha ka pH i ka desalination a me ke ola o nā membrane reverse osmosis?

E like me ke kaʻina hana kānana nui i nā mea hoʻomaʻemaʻe wai, hoʻoholo nā mea hoʻohuli osmosis inā e hoʻopōʻino ʻia ka waiwai pH o ka wai maka i loko o ka membrane reverse osmosis. ʻO ka ʻōlelo maʻamau, hoʻohana mau ʻia nā mea membrane composite no nā membrane osmosis reverse. Inā loaʻa ka waiwai pH i loko o ka laulā o 2-11, e liʻiliʻi ka pōʻino a me ka hopena o ka waiwai pH ma ka membrane ponoʻī.

E like me ka hopena o ka pH ma ka desalination rate o ka reverse osmosis membranes, ua hoʻoholo ʻia e nā hiʻohiʻona o nā ion like ʻole i ka wai i hoʻopili ʻia e ka waiwai pH. ʻO kēia ma muli o ka acidity, decomposability, a me ke degere o ka hoʻopiʻi ʻana o nā ion iā lākou iho, ʻo ia nā mea āpau e hiki ke alakaʻi i ka emi ʻana o ka desalination rate o ka membrane.

Hiki ke ʻike ʻia he hopena koʻikoʻi ka pH i ka helu desalination o kekahi mau haumia. Pēlā nō, inā ʻaʻole ka helu o ka wehe ʻana o CO2 e ka membrane reverse osmosis a hoʻonui ʻia ka waiwai pH o ka wai maka e hoʻololi i ka CO2 i CO32-, hiki i ka membrane reverse osmosis ke desalinate maikaʻi. Akā i kēia manawa, pono e uku nui ʻia i ka pilikia scaling o ka membrane reverse osmosis.
