摘要: Device to simulate operation and placement of a reverse osmosis membrane element in a Reverse Osmosis Water Purification Unit (ROWPU). The device simulates the drop in hydrostatic pressure occurring when a liquid (usually water) is forced across a membrane which separates different concentrations of solutes in the same solvent system. When substituted into a typical ROWPU for an actual reverse osmosis (RO) element, the drop in hydrostatic pressure is effected by an aperture or series of apertures which allow passage of liquid directly from the intake liquid piping to the purified effluent piping. The hydrostatic pressure of the waste effluent is similar to the pressure present in the waste effluent when an actual RO element is operating in a ROWPU.
