Abstract
A method for treating sludge comprising the steps of a) separating the sludge into a BOD-rich portion and a BOD-poor portion; and b) adding flocculant to the BOD-rich portion after the separating step. A currently preferred method comprises the steps of a) first passing the sludge through a sludge classifying press to create a classified sludge; and b) adding at least one flocculent to the classified sludge after the passing step. The method may comprise the further steps of separating grit from the sludge by preliminarily passing the sludge through a grit separator prior to the first passing step; and/or thickening the classified sludge by second passing the classified sludge through a sludge thickener after the adding step.
Claims9
A method for adaptively treating sludge in a sludge treatment system to selectively remove components from the sludge, comprising the steps of a) first passing said sludge through a sludge classifying press to create a classified sludge;
- and b) adding at least one flocculent to said classified sludge after said passing step.
A method for treating sludge, comprising the steps of a) separating said sludge into a first sludge portion rich in biological material and a second sludge portion poor in biological material;
- and b) adding at least one flocculent to said first sludge portion after said separating step.
