Project: WWTP Biosolids Removal

Project: Antigonish WWTP Biosolids Removal
Client: Town of Antigonish

The Antigonish Sewage Treatment Plant sludge (1996 & 2005) had the initial stage which involved removing sludges from a twenty year old lagoon system prior to rehabilitation with a new raised wall six cell lagoon and a continuous sand filter. The new STP, after six years of operation, had a sludge quantity/quality test program undertaken jointly by ABL Environmental Consultants and C.J. MacLellan & Associates which recommended disposal by dewatering and biosolids composting at the Guysborough landfill.

A tender in late 2004 resulted in dredging and pumping the sludge biosolids through pre-screens, flocculation tank, and twin centrifuges for dewatering, with 220 bone dry tonnes hauling for composting and stabilization. C.J. MacLellan & Associates Inc provided contract administration, inspection. and sampling/testing services to the Town of Antigonish.
