7/26/2021 Zhaohui An received NSF support for this internship research work on continuous flow aerobic granulation in Upper Occoquan Service Authority (UOSA)

It is a great honor and timely impetus for Zhaohui to received this NSF award. His continuous flow aerobic granulation research is at the stage of field test in real wastewater with diurnal influent quality variation and seasonal temperature impacts. We also appreciate UOSA for providing such a strong infrastructural and mentoring support for Zhaohui…

7/2/2021 Congratulate Zhaohui on his new publication on the topic of “Leveraging feast and famine selection pressure during startup of continuous flow aerobic granulation systems to manage treatment performance”!

https://doi.org/10.1039/D1EW00314C Abstract: Hydraulic selection pressure that selectively washes out flocculent microbial sludge has been a conventional approach to drive flocculent systems towards aerobic granulation. Such substantial sludge washout inevitably compromises treatment performance during reactor startup, which is unacceptable in full-scale applications of aerobic granulation technology. This study explored the possible use of feast and famine…

6/8/2021 Zhaohui and Xueyao published their GMBR paper in Processes

Abstract: The structure of nitrifying granules can remain stable for 305 days in a granule membrane bioreactor (GMBR) without hydraulic selection pressure; however, majority of the granule structure was actually inactive due to mass diffusion limitation. As a consequence, active biomass free of mass diffusion limitation only inhabited the top 60-80 ┬Ám layer of the nitrifying…
