A plate and frame membrane stack was designed and constructed for use in laboratory scale experiments on pressure driven membrane processes. Three novelties were applied in this stainless steel stack. The first is using a multilayer support including various steel nets. The second is making parallel grooves in the permeate compartment to improve uniformity of permeation stream through membrane surface. The last one is that the back side of feed compartment was hollowed out for holding hexagonal bolt heads immobile, results in simpler assembling or disassembling of the stack. A high pressure dosing pump, a back pressure regulator, two pressure gauges, two flow meters and some other facilities were also installed in an integrated platform to have a lab scale unit for membrane processes with controllable parameters including pressure, flow rate and temperature. The unit could be used for researches related to reverse osmosis, nanofiltration, ultrafiltration and microfiltration. Entire the path, which pressurized water flows through, is resistant to both pressure and corrosion.
