8/17/2021 Field tour of the pilot-scale thermal hydrolysis anaerobic digestion setup in Loudoun Water Broad Run Water Reclamation Facility.
This system can double the total solid concentration and halve the solids retention time used in anaerobic digesters, directly upgrading the treatment capacity of existing anaerobic digesters for four times.
8/11/2021 Congratulation to Zhaohui and Xueyao for their new publication titled “Aerobic granulation of single culture protist” in Process Biochemistry!
https://doi.org/10.1016/j.procbio.2021.08.014 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…
8/5/2021 Field tour of our 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.
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 my 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.
