CASE HISTORY: Coleraine Wastewater
APPLICATION: AFC Process on Municipal

Challenge
The AFC is well-proven for destruction of waste biosolids from industrial wastewater treatment processes. The purpose of this plant was to evaluate the effectiveness of the AFC process for treating municipal waste activated sludge (WAS).

Solutions
A portable AFC pilot plant was operated for a period of seven months and fed waste activated sludge from the Colerain treatment facility. COD removal for the WAS treated averaged 97%. TSS destruction was 84%. The AFC process was resilient through extreme loading and temperature variations. The integral ChemTreat process proved an effective means to control reactor solids, COD levels, and foaming.

Bottom Line
This 7 month test was performed at the Coleraine Wastewater Treatment Plan (WWTP) in Northern Ireland. From the Final Report on “A Pilot–Scale Study of the Advanced Fluidized Composting (AFC) Process at Coleraine Wastewater Treatment Works”: “The AFC Process has been demonstrated to be more dynamic and robust than any other biological digestion process currently in operation at wastewater treatment works.”
