The experiments were performed on a laboratory scale filtration setup with vertical downward fluid flow orientation (Fig. 1). Isooctane in deionised water emulsion (0.2% by weight) was prepared by high speed mechanical agitating (3) followed by ultrasonic treatment. The emulsions were stabilized by adding 0.00005% sodium dodecyl sulfate surfactant. For all the filter media the emulsion was continuously pumped through a peristaltic pump (4) at its constant rpm. The samples for the permeate concentration were collected after reaching steady state condition, where the steady state confirmation was done with the stabilisation of the pressure drop across the filter (Fig. 1) (7).
