Any effect of hydrolysis on reverse draw solute performance in FO?

21 February 2017 1 820 Report

I saw some explanation on the effect draw solution at high pH which hydrolyze CA FO membrane. Can anyone explain to me further? Does it applicable to CTA FO membrane? What is the mechanism behind this?

pH range for membrane operation is usually between 2 to 11. If pH is more than 11 the membrane will be damaged. You can ask the membrane manufacturer and let us know.
