Abstract
A mathematical model of a depth filter that removes colloidal particles from suspension by reversible adsorption is studied. The filtration problem is analytically solved when the adsorption and peptization coefficients are written as a function of van der Waals, electrical double layer, and Born interaction potential energies. The solution is used to study the performance of a depth filter as a function of the size of colloidal particles, filtration velocity, specific filter surface area on which reversible adsorption takes place, and filter depth.
