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.
