The trickling filter process in which a bacterial biomass is allowed to grow attached to a filter medium of rock or plastic is effectively used for removal of organic materials in domestic wastewater. The design of a filter unit incorporates empirical equations that are specific to the medium chosen. A comparison of the design results for the two types of media is presented in this paper.
