8/11/2021 Congratulation to Zhaohui and Xueyao for their new publication on Process Biochemistry!
Abstract: Thraustochytrium striatum was selected as a model protist to test the possibility of protist granulation for its good potential of organic waste valorization. Initially, only a selective settling velocity of 9 m h 1 was applied in a sequential batch reactor (SBR) with minimal granulation progress after three months. After the famine condition was introduced into…
8/5/2021 Field tour of pilot-scale continuous flow aerobic granulation reactor in Upper Occoquan Service Authority
This pilot is a gold mine of our team! About eight journal papers and two Ph.D. dissertations have been produced from this one pilot reactor. It tested our hypotheses of the continuous flow aerobic granulation mechanism and verified the reactor performance under diurnal and seasonal influent quality fluctuation over several years of continuous flow operation.
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…
7/27/2021 Field tour of our pilot MBBR-Anammox reactors stationed in Noman M. Cole Jr., Pollution Control Plant
Finally Dr. Wang’s research team is able to come out and get together for a series of field tours of our pilot experimental systems stationed in utilities across Washington DC metropolitan area. This particular pilot system has been polishing low concentration of nitrogen residual from tertiary treatment through partial denitrification and anammox reactions.
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.…
