Can you say more about the "proper CIP program" mentioned here? What does cleaning in place look like for an RO membrane?

Clean in Place is the ordinary way we clean membranes without removing them from vessels.
High pressure pump stops and low pressure pump performs a sequence of washings with acidic/alkaline/biocide solution discharging the used solution.
A CIP program is based on foulants found in the feedwater and must be implemented along with the system design as a normal operative procedure: that's why (almost-) any RO unit is equipped with onboard CIP tank and chemical dosing pump (or separate skids) and HMI often features automatic cleaning phases based (usually) on working hours.
