ABSTRACT:
The method of treating sewer scum including combustibles and debris includes the steps of collecting the scum from sewage, delivering it to a perforated filter drum, continuously rotating the drum upon an inclined longitudinal axis, applying heated air under pressure to the exterior of the drum along its length inwardly of the perforations, discharging the debris continuously and collecting the filtered combustibles. Apparatus for filtering said scum includes an elongated cylindrical perforated drum rotatable on an inclined axis receiving scum at its upper end and discharging debris at its lower end. A cylindrical shell sealingly encloses the perforated portion of the drum for providing a pressure chamber above the drum and a collection chamber below the drum. An elongated air channel along the interior of the shell delivers high pressure heated air to said pressure chamber and filtered scum accumulates in the collection chamber.
