Physical characterization of a phytodewatered anaerobic sludge

Abstract

Some physical parameters were determined on an organic product derived from a new phytodewatering process of anaerobic sludge, in order to verify its possible use as a substrate. Wetting-drying cycles were carried out with a sandy soil, and with mixtures of this soil with the organic product taken before and after the phytodewatering process. The phytodewatering process decreased bulk density while raising aggregate stability and friability.
