Water Scenario India has a population of 1 billion 70% of irrigation & 80% of Domestic needs is met through Ground water Per Capita Water water availability is likely to fall to 1000 cubic meters per year in 2020 as compared to 2000 cubic meters per year in 1997.

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

High Pressure Membrane

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.
