In the work the micro-filtration processes in fresh natural waters are considered. The effect of the variation of the height of the forcing chamber on the membrane flux of the pure water as well as the problem of extrapolation of the relationship between various turbidity of model solutions and productivities were studied. By means of experimental curve of mentioned relationship the analytical view at extrapolation curve was established. It has been found that at baromembrane filtration the various turbidity of the model solutions determines the variation of asymptotic values of flux of the pure water. The efficient regulation and further prediction is possible in the conditions of the variation of the height of forcing chamber at equal energetic consumption.

By experimental results it was established that in the course of baromembrane filtration in the range of various turbidity from 1 to 40 NTU the extrapolation curve of the relationship between asymptotic values of model solutions and flux of the pure water represent square paraboloid. Reserch process was carried out on laboratory scale. Flux of the pure water was determined end experimentally at laboratory plant Turbidity of model solutions was by measured turbidity measurer.
