The results show that both surfactant and enzyme are more efficient for cleaning membrane fouled with protein mixture and whey. 0.6 0.4 0.2 0.8 0.6 0.4 0.2 (a) Flux recovery Resistance removal Flux recovery 0.8 HCl, 0.1 M NaOH, 0.1 M SLS, 0.75 wt% TAZ, 1 wt% HCl, 0.05 M NaOH, 0.1 M SDS, 1 wt% (b) Fi

The role of EPS is not clear to date. A literature review suggests that its importance is greater at lower SRTs and during unsteady operation. Fluctuating levels of dissolved oxygen and nitrate appear to have a profound impact on EPS uptake rate and thereby on EPS concentration. However, higher diss

Laboratory experiments and detailed atomistic packing models of polymer/gas systems have been analysed and the results could be compared with satisfying agreement. The interpretation of the results in view of the chosen phenomenological models provides insight into the physics of the underlying proc

As a result of our experiment we have arrived at the following conclusions: the water content and its state in polymer structure have a decisive influence on the character of the concentration dependencies of the membranes transport properties.
