Columbus: How To Improve Dewatering And Thickening Performance While A Facility Is Under Construction?

When Columbus Water Works shut down its dewatering and thickening systems for a major upgrade, sludge kept accumulating daily. Orege delivered a preconfigured mobile rental system: two belt filter presses and two rotary drum thickeners, all equipped with SLG® technology. Dry cake solids rose from the historic 18% to 23%, reducing hauling volumes and daily truckloads. Thickened sludge concentration climbed from 6-7% to 8-9%, and lower polymer use produced six-figure savings. "We turned to Orege to keep our operations running. They did much more than that," said Julio Baez, Biosolids Labor Foreman.
