Please What is the procedure for cleaning RO membranes? And which one should always be performed first The high pH cleaning Or The low pH?

I have put a link to a reasonable paper on cleaning. Unless you are absolutely certain that you have no biofouling always go with a high pH first.

RE: RO membranes CIP

You need to talk to the manufacturer of the RO system. RO membranes from different manufacturers may be fabricated from several different materials and each of the membrane manufacturer's has developed a cleaning procedure that is suited for their membranes.
