Abstract: This paper researches three main factors that influence membrane fouling: Mixed Liquor Suspended Solid (MLSS), pressure and temperature, and establishes a conjunctive mathematic model based on the separate analysis of the impact on membrane flux caused by these three factors. And by analyzing the experimental data obtained by treating industrial wastewater, we establish the mathematical model of membrane flux combined with the three factors, and optimize the parameters of the mathematical model using Particle swarm algorithm. The experimental data obtained by the mathematical model fits the actual data well, and this model has a more accurate simulation and prediction on the process of the treatment on MBR.
