Vacuum-dry Membrane (10mbar, 110oC and 120oC) • The stand-alone membranes were vacuum dried at 110oC and 120oC, respectively; The PA conc. of the membrane were measured at 10mins, 20mins, 30mins, 60mins, 2hrs and 3hrs. • PA Conc. of the membrane increased to over 100% after 10mins when heating at both 110oC and 120oC, suggesting that the previous data from Ru may have issues.
