Puas yog pH cuam tshuam rau desalination thiab lifespan ntawm rov qab osmosis membranes?

Raws li cov txheej txheem tseem ceeb hauv cov khoom siv kho dej, cov khoom siv rov qab osmosis txiav txim siab seb tus nqi pH ntawm cov dej nyoos nkag mus rau qhov rov qab osmosis daim nyias nyias yuav ua rau muaj kev puas tsuaj rau daim nyias nyias. Feem ntau hais lus, cov ntaub ntawv sib xyaw ua ke feem ntau yog siv rau rov qab osmosis membranes. Yog tias tus nqi pH nyob hauv thaj tsam ntawm 2-11, qhov kev puas tsuaj thiab cuam tshuam ntawm pH tus nqi ntawm daim nyias nyias yuav tsawg.

Raws li kev cuam tshuam ntawm pH ntawm desalination tus nqi ntawm thim rov qab osmosis membranes, nws yog txiav txim los ntawm cov yam ntxwv ntawm ntau yam ions hauv dej uas cuam tshuam los ntawm pH nqi. Qhov no yog vim lub acidity, decomposability, thiab degree ntawm tus nqi ntawm cov ions lawv tus kheej, uas yog tag nrho cov yam uas yuav ua rau kom ib tug txo nyob rau hauv lub desalination tus nqi ntawm daim nyias nyias.

Nws tuaj yeem pom tau tias pH tseem muaj feem cuam tshuam rau tus nqi desalination ntawm qee yam impurities. Ib yam li ntawd, yog tias qhov kev tshem tawm ntawm CO2 los ntawm qhov rov qab osmosis membrane yog xoom thiab pH tus nqi ntawm cov dej nyoos yog nce ntxiv los hloov CO2 rau CO32-, qhov rov qab osmosis membrane tuaj yeem desalinate zoo. Tab sis lub sijhawm no, kev saib xyuas tshwj xeeb yuav tsum tau them rau qhov teeb meem ntawm qhov rov qab osmosis membrane.
