What is CIP-cycle?
A single Clean-In-Place run — typically a sequence of caustic flush, acid flush, then rinse — used to remove biofilm, mineral scale and organic foulants from a system between production batches.

- CIP
An automated cleaning cycle that flushes a piping system or RO train with hot water and detergents without dismantling it. Standard practice in food, beverage, dairy and pharma to keep surfaces sanitary between batches.
- SDI
A 15-minute filter test that quantifies how much suspended fine matter is in the feed. RO membranes need SDI < 5 to avoid premature fouling.
- FR
Membrane variant with a more open feed-spacer and tweaked surface chemistry to handle high-fouling streams (textile, food, ETP) before scaling forces a clean.
