Combining submerged membrane technology with anaerobic and ...

Impact of a methanogenic pre-treatment on the performance of an aerobic MBR system Batch experiments demonstrated that the hydrolysis of aerobic biomass inanaerobic conditions led to a release of biopolymers, and hence an increase in TEP,colloidal BPC, SMP carbohydrate and SMP protein concentration. It was demonstrated that the presence of plastic support positively influencemembrane performance. As expected, MLVSS concentration was shown to be an important parameter inorder to protect the membrane against the fouling provoked by soluble and colloidalbiopolymers.5.6.
