    Abstract

    Computational results show that a cylindrical cross-flow filter hydrocyclone with a length ratio, L/D equal to 4 performs best over a range of operating conditions. The increased residence time associated with a longer CFFH is lost due to the weakened angular momentum in the outer vortex from the flux to the inner core. For higher Reynolds numbers the tangential and axial velocities increase. While this trend improves the separation due to an increase in acceleration, the residence time decreases. For a split ratio equal to 50%, predicted oil droplet diameters must equal 300 μm. With respect to experimental testing of the porous filter, the oil concentration from the permeate (underflow) has been lowered to 0-15 mg/L with the 1.4 μm microfiltration membrane. However, the permeate flux decreases very rapidly within the filtration time. By introducing a centrifugal flow inside the membrane, as in hydrocyclones, the membrane is expected to have an improved performance with low oil fouling.
