Wasting Through The Spin Cycle: A Full-Scale Demonstration of WAS Hydrocyclones to Provide Capacity Improvements

Abstract

The Upper Occoquan Service Authority (UOSA) identified the need for increased secondary treatment capacity at the Millard H. Robbins, Jr. Regional Water Reclamation Plant (RWRP) to meet future raw sewage flows and loads. UOSA is undertaking a pilot study at the RWRP to compare full-scale performance with and without waste activated sludge (WAS) hydrocyclones, to identify if selectively retaining dense, fast-settling material using WAS hydrocyclones will have a substantive effect on sludge settleability, thereby demonstrating that higher flows and loads can be treated with existing secondary treatment infrastructure. Results from the first ten months of pilot operation indicate that the hydrocyclones have a positive impact in improving mixed liquor settleability during winter operation, as evidenced by sludge volume index (SVI) measurements and clarifier flux analyses.
