Not every utility that cleans wastewater views itself as a wastewater treatment plant.
“Some utilities have started making the shift from saying ‘we make clean water’ to saying ‘we recover resources from water,’” said Matt Williams, an anaerobic digestion/biosolids expert from WesTech. “They are seeing themselves as water resource recovery facilities.”
These utilities are using anaerobic digestion to turn their biosolids into biogas — a renewable energy source. Williams shares five reasons why every wastewater treatment plant should consider doing the same.
