Description
Summary:A company in Rockland, Me., had developed a system for managing septage to produce compost that was destined for land application. The system included dewatering the septage, odour control and in-vessel composting and produced a filtrate that had very favourable levels of suspended solids and BOD and which was acceptable as an industrial effluent. Prior to composting, the dewatered solids were mixed with sawdust from local sawmills. The materials being composted remained in the vessel for 21 d and met all federal and state regulations, particularly those relating to odour control.
