Clean-in-place (CIP)
Recirculating low-pH and high-pH cleaning solutions through the pressure vessels to remove scale and foulants — commonly when normalized permeate flow has fallen 10–15%, normalized salt passage has risen 5–10%, or differential pressure has risen about 15%.

RO operation and performance normalization
Running pressure vessels at a set recovery and flux, and normalizing permeate flow, salt passage and differential pressure to standard temperature and pressure so that membrane condition can be seen through changing feed conditions.

RO pretreatment
Media or membrane filtration, cartridge filters, antiscalant dosing and dechlorination ahead of the membranes, to protect them from particles, mineral scale, biofouling and oxidation of the polyamide layer.
