These membranes should have been chemically cleaned/treated. When you have fowling as you have, you can not clean the membranes by just flowing water from the permeate port, which is probably the cause of the damage. There are ways to clean the membranes by reversing the flow through the permeate ports but not advisable if you do not know how to do it. Reversing the flow in these types of membranes (RO or Nano) is tricky. Do you know at what pressure the contractor used to clean the membranes?
