18. High Pressure membrane Reverse Osmosis Vibratory Shear Enhanced Process Membrane Separation Desalination Technologies

19. High Pressure Membrane

20. A VSEP filter uses oscillatory vibration to create high shear at the surface of the filter membrane. This high shear force significantly improves the filter’s resistance to fouling thereby enabling high throughputs and minimizing reject volumes. VSEP feed stream are split into two products—a permeate stream with little or no solids and a concentrate stream with a solids concentration much higher than that of the original feed stream.
