Virus transport in saturated one-dimensional porous media C.V. Chrysikopoulos, Y. Sim Department of Civil and Environmental Engineering, University of California, Irvine, CA 92717, USA ABSTRACT A new mathematical model for virus transport in one-dimensional homogeneous, saturated porous media for a constant flux boundary condition is developed, accounting for first-order inactivation of suspended and filtered viruses with different inactivation constants. The virus attachment onto the solid matrix is considered as a filtration process which is suitable for viruses behaving as colloids. The closed-form analytical solutions are developed for a semi-infinite porous medium by Laplace transform techniques. The impact of the model parameters on virus transport is examined. INTRODUCTION Viruses are intracellular parasites that can be classified as colloid particles with size ranging from 0.02 ^m to 0.3 //m [15]. They are generally negatively charged and vary widely in shape and chemic
