Abstract

A membrane deposition and growth model based on fractal theory was developed. This model can dynamically describe the fouling process on the outer surface of membranes. Using this model to change boundary conditions and initial particle production probabilities, the process of membrane deposition and growth was simulated under different conditions. Micro-PIV technology was applied in a membrane fouling observation experiment. The morphology of membrane deposits was determined using quantum dot fluorescent tracers, and the surrounding flow field was simultaneously observed and analyzed. The fractal dimensions obtained were as expected. Findings indicate that membrane deposition and growth model developed in this work describes real phenomena accurately. The model was used to simulate the impact of flow field and suspended solid concentration on dynamic variations in membrane deposition.
