A study was conducted to investigate the effects of transmembrane pressure, membrane rotational speed and feed oil content on permeate water quality in the treatment of a synthetic metal working fluid in the HSRUF system. Permeate oil grease and total organic carbon concentrations increased with transmembrane pressure and feed oil content due to the increased density or thickness of the solute concentration boundary layer. However, hydraulic turbulence created by membrane rotation minimized the thickness of the solute concentration boundary layer therefore reducing solute permeation through the membrane. The effective decoupling of feed pressurization/recirculation from hydraulic turbulence enables the HSRUF system to provide better permeate quality as well as increased permeate flux in the treatment of highly concentrated oily wastes.
