8/3/3021 Received another DOE grant

The funded study (DE-EE0009667) will be performed between 10/01/21 and 9/30/2025. It targets understanding the characteristics critical to turning low-cost, abundant municipal solid waste (MSW) into conversion-ready feedstocks for producing biofuels through gasification and solid-state anaerobic digestion (SS-AD) as targeted thermal and biological conversion technologies with final Fischer–Tropsch (F-T) processing to liquid hydrocarbon fuels. The…

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 Environ. Sci.: Water Res. Technol.

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 conditions…

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 µm layer of the nitrifying granules.…
