WEAT's Central Texas Section will hold our final lunch meeting of the year at Hornsby Bend - this meeting's lecture topic is "Chemical Phosphorus Removal" with UT Ph.D. candidate William Wehner.
With the recent rises of phosphorus permit requirements, the need to add chemicals for phosphorous removal has increased. Additional solids production and alkalinity consumption due to chemical addition and increasing chemical costs result in environmental and economic concerns requiring the WRRFs to optimize the design and operation of a chemical dosing system. Understanding the removal mechanisms and identifying the operational and design parameters are critical for designing and operating an efficient chemical phosphorus removal system.
William Wehner is a Ph.D. student with the University of Texas specializing in research on Biosolids. He previously was working for HDR where he helped design and construct process improvements at over 20 WWTPs in his 8 years of experience. During his time with HDR, Will became involved with the WEF MRRDC Phosphorus Removal Design Group and leads the subgroup for Chemical Phosphorus Removal. So far the group has produced a white paper detailing an overview of Chemical Phosphorus Removal and presented the content of the paper at WEFTEC in Chicago.
