Separation of Oil/Water Emulsion from Kitchen Using a Novel Tubular Membrane

Abstract:

This paper introduced an approach that a novel tubular membrane was used to separate oil/water emulsion from kitchen wastewater. Separation capability of the tubular membrane and its regeneration performance after repeatedly membrane cleaning were investigated. The results showed that oil removal was up to 99.8% and the concentration of filtrate was less than 20 mg/L, which met the requirement for discharge. The suitable operating pressure and treatment concentration is 0.10 MPa and less 15 g/L respectably, the best way to clean membrane is washing it using clean water every 20 min and membrane flux recovery value of 99% or more was achieved. Results above suggested that the membrane had excellent performances for oil/water emulsion treatment and good application prospect.
