Drive water through a selective barrier. A crossflow hollow-fiber module separates permeate from concentrated retentate while rising resistance reduces flux.
• 3D scene parts: Crossflow feed pump; hollow-fiber bundle; module housing / ports; permeate manifold; retentate return. • Controls: Transmembrane pressure (0.2–3 bar); Membrane area (5–50 m²); Feed flow (1–10 m³/h); Feed solute concentration (20–200 mg/L); Solute rejection (0.5–0.99 fraction); Resistance growth (0–2 10¹² m⁻¹ per process h). • Live readouts: Permeate flux (L/m²/h); Permeate flow (m³/h); Retentate concentration (mg/L); Total resistance (10¹² m⁻¹). • Guided experiments: Fouling suppressed; Lower pressure. • Four tabs (visual laboratory, curves and measurements, experiments, learn and assess), a model-verification run, a timestamped event log and a trial report.

Prescribed resistance growth; all rejected solute exits in retentate, with no solute stored in a cake. Feed-limited permeate is capped at 95% recovery. No osmotic pressure, cleaning chemistry or concentration-polarization model. Try the preset experiments, then compare the live readouts with the equations.
Pressure and resistance set the flux..
No. Prescribed resistance growth; all rejected solute exits in retentate, with no solute stored in a cake. Feed-limited permeate is capped at 95% recovery. No osmotic pressure, cleaning chemistry or concentration-polarization model.
