We introduced the theory of thin bed filtration which mash filter is based upon,and the advantages over other mash separating methods that new modern automatic mash filters give.

Advances in study on the theory and technology of deep bed filtration;

Mathematical model for unit filter in deep bed filtration;

The deep bed filtration is one of the basic methods for the heterogeneous separation in chemical engineering, which plays an important role in the petrochemical wastewater treatment.

The mathematical model of deep bed filter process and the outline of its mechanism;

The deep bed filter is one of the basic units in water treatment engineering,it plays an important role in the produced water treatment of oil field and waste water treatment of refineries.
