SUMMARY

On the basis of theoretical and experimental studies, the regime parameters of the ultrafiltration water
separation process under turbulent flow conditions have been studied. Under conditions of 0.1 mm,
0.2 mm, 0.4 mm, 0.6 mm, 1 mm height of the pressure cell of the membrane device. Comparison of
experimental results with theoretical studies showed that in the transient turbulent regime, the
relationship between the pressure cell height and the specific performance values is curvilinear, the
specific performance increases in the pressure cell height range of 0.1mm-0.6mm, and decreases in the
range of 0.6mm-1mm. In the developed turbulent regime, the relationship between the height of the
pressure cell and the performance values is linear, the specific performance decreases with the increase
of the cell height.
