ASTM D4472 CIP Trigger Criteria:

Membrane manufacturers (FilmTec, Toray, Hydranautics) mandate cleaning when ΔP rises > 15-25% or Normalized Flow drops > 10-15%. Delaying past this threshold causes irreversibly compacted cake layers.

Alkaline Wash First Required
Identified Foulant Class

Stage 1 Biofilm & Silt Cake

Elevated Stage 1 ΔP (37.2 PSI) with relatively mild Stage 2 ΔP (22.1 PSI) indicates organic slime, bacterial EPS, or colloidal matter capturing feed spacer channels.

Critical Protocol Directive

DO NOT START WITH ACID

Applying acid clean (low pH) to heavy organic bio-matter will precipitate and permanently coagulate organics onto the membrane pores. Clean with High pH first.

Recommended 2-Step CIP Flow
1

High pH Alkaline Clean (Primary)

0.1% NaOH + 0.1% Na4-EDTA @ pH 11.2, 95°F (1 hr recirc + 2 hr soak) to disperse bio-slime.

2

Low pH Acid Clean (Secondary)

2.0% Citric Acid @ pH 2.3, 86°F to dissolve residual calcium phosphate or iron scales.
