Kev ua haujlwm siab ntawm kev kub siab rov qab osmosis membranes yog qhov siab, feem ntau ntawm 2.8 thiab 4.2 MPa. Nws cov dej ntau lawm kuj me me, tab sis nws cov desalination tus nqi siab thiab cov nyhuv desalination kuj zoo dua. Kev kub siab rov qab osmosis daim nyias nyias yog siv hauv kev lag luam, xws li seawater desalination membranes (desalination membranes) thiab siab concentration brackish dej desalination;
Kev ua haujlwm siab ntawm qhov qis rov qab osmosis membranes yog qhov qis, feem ntau ntawm 1.4 thiab 2.0 MPa. Nws cov dej ntau lawm kuj loj dua, tab sis nws cov desalination tus nqi yog qis dua li ntawm high-pressure reverse osmosis membranes. Tab sis precisely vim hais tias ntawm lub low-pressure ua hauj lwm ib puag ncig, nws lub zog noj kuj yuav txo tau. Tsis tshua muaj siab rov qab osmosis daim nyias nyias yog siv los tsim cov dej purity siab hauv cov khoom siv hluav taws xob thiab kev lag luam, kev kho dej khib nyiab hauv kev lag luam zaub mov, thiab kev tsim dej rau cov dej haus.
