Hermia’s models categorize TFF fouling into four mechanisms, guiding regime identification and critical flux determination. Effective CIP protocols use caustic/acid washes to recover permeability. Digital twins combine mechanistic cores with AI to predict flux decline.

How to use the result to minimize fouling in production TFF

• Set your operating flux below the measured critical flux (often with a safety factor) to avoid sustained resistance growth.

• If you observe a TMP “jump” pattern above certain fluxes, treat that as entering a new fouling regime and back off; TMP-jump behavior above critical/threshold flux is discussed as a characteristic signature in constant‑flux fouling studies.

• Re-measure critical flux when any major variable changes (broth solids/viscosity, temperature, membrane lot, crossflow/channel geometry), because critical flux is not a membrane constant; it is an operating‑condition-dependent boundary.
