JTAC Presentation

 Pilot Scale Evaluation of AirPrex for Phosphorus

Thursday, April 20th, 2017

On line Registration

Description: Waste sludge from biological phosphorus removal (Bio-P) systems has been associated with negative impacts to anaerobic solids digestion and dewatering processes. Ahead of instituting a full plant Bio-P process, Metro Wastewater Reclamation District’s Robert W. Hite Treatment Facility conducted an in-depth pilot scale investigation of AirPrex™ (CNP Technology Water and Biosolids Corp., Kenosha, WI) as a possible approach to mitigate undesirable effects of Bio-P on the RWHTF’s solids treatment and handling processes. Analysis results and subsequent modeling were used to evaluate the technology against five primary criteria: phosphorus recycle control, biosolids dewatering, nuisance struvite reduction, minimization of phosphorus in biosolids for land application, and product recovery.
Speaker: Blair Wisdom, Process Engineer (MWRD)
