Is It Time to Replace the Belt Presses? Why Dewatering is More Than Just Getting the Water Out!
Abstract
Renewable Water Resources (ReWa) in Greenville, SC, initiated a dewatering evaluation in 2021 to explore alternatives for dewatering anaerobically digested biosolids from three of their Water Resource Recovery Facilities, Mauldin Road, Pelham and Lower Reedy. The objective of this project was to provide engineering services for evaluation of the remaining useful life or replacement of existing belt filter press (BFP) sludge dewatering equipment with new BFP, centrifuge, or screw press dewatering equipment. Bench Scale testing was conducted considering several technologies and onsite pilot testing of a centrifuge was conducted and compared to the existing BFP. A unique part of the study included comparing the fecal coliform regrowth and odor potential from both the centrifuge cake and BFP biosolids. All facilities showed fecal coliform regrowth and increased total volatile organic sulfur compounds with centrifuge dewatering, as expected, but one facility also showed regrowth with belt filter press dewatering.
Renewable Water Resources (ReWa) in Greenville, SC, initiated a dewatering evaluation in 2021 to explore alternatives for dewatering anaerobically digested biosolids from three of their Water Resource Recovery Facilities. The purpose of the evaluation was to identify the best technology to support ReWa's long-term Biosolids Master Plan, reduce the cost of biosolids management and to ensure a high quality of biosolids for their current and future biosolids management program.
