An apparatus and method for filtering and classifying waste or process streams into three product streams using a polymeric net belt to drive a filter drum and hydrophobic polymeric filter element thereon. A matte of solids is doctored from the belt to provide a first product stream. A roller mounted on a fluid cylinder driven pivoted arm compresses the filter element to provide a smaller suspended solids stream for collection in a trough inside the drum. This second product stream is removed axially from the trough by means of a pump. A third clarified or effluent stream is produced and collected in the drum as the stream passes through the foam filter element. This third stream is removed axially in the direction opposite of said second stream. A shower keeps the foam in the compressed area water filled to prevent vapor lock or gas blockage in the cellular foam filter.
