Abstract

The main objective of this work is to study the effect of hydrodynamics and microstructure parameters which includes characterization and crossflow filtrations on ceramic membrane for the separation of oil -in-water emulsion. Firstly, the 6000nm unmodified ceramic membrane was characterized for porosity, contact angle and pore size using equation, Attention Thetalite meter and N2 adsorption/desorption isotherm instruments respectively. Subsequently, cross flow microfiltration was carried out using pure water at four distinct applied flowrates (25, 50, 75, 100L/h) which generated and reflected four pressures (0.15, 0.35, 0.46, and 0.67 bar). Compared to existing literature the porosity of the modified membrane was 0.2 and contact angle was 75.330 which indicates a low level of hydrophilicity and would need modification for separation of oil-in-water emulsion. Results from the microfiltration shows that and increase in pressure on the unmodified membrane gave an increase in flux. This microfiltration was run 30 minutes for each pressure and permeate volume was measured every five 5 minutes to observe and change in flux with time. Where a 0.15, 0.35, 0.46 and 0.67bar pressures gave a flux of 4.1x10-5, 9.0x10-5, 0.00016, and 0.00025(L/m2h). This flux measurements corresponds vividly with the porosity results as this flux value represents and agrees with the porous nature of the membrane.
