Principal Investigator: Manuel Alvarez Cuenca

The primary research conducted in this lab is focused on two main areas associated with the treatment of water/wastewater: vertical bioreactors and microbial processes. The reactors used in the WTL are based on innovative reactor engineering, including three-phase fluidized beds, bubble columns, and fixed-film reactors like rotating biological contactors and multistage vertical bioreactors. Large scale dimensions, as opposed to bench-scale reactors, are preferred in the lab since they better reproduce the fluid mechanics of large flows found in many of the industrial processes studied.
