Past Students

Vinny Anderson, PhD 2021, Membrane Filtration Processes for Energy Reduction, Brine Treatment, and In-situ Ultrasonic Biofouling Mitigation

Vinny Anderson completed his undergraduate study in autumn 2015 with a bachelor’s degree in environmental engineering from Ohio State University. He continued into a PhD program within the Civil, Environmental and Geodetic Engineering Department under Dr. Weavers in spring 2016. Vinny’s research focus is on understanding the capabilities and energy demands of novel membrane technologies. His research in the field of membrane filtration began with a coupled forward osmosis – membrane distillation (FO-MD) process to treat flue gas desulfurization (FGD) wastewater. This work investigated the capacity of a coupled FO-MD approach to meet FGD wastewater discharge regulations and provided optimum operating conditions. In addition, the feasibility of utilizing on-site residual waste heat (from the coal fired power plant) to drive MD was studied. With the utilization of waste heat, the FO-MD system may prove to be a sustainable approach to FGD wastewater treatment, obtaining high-quality finished water with minimal energy input.
Vinny’s work then shifted to a second membrane filtration process: electrofiltration. This research focused on characterizing the energy requirements of an electrofiltration process using microporous alpha alumina membranes. In electrofiltration an electric field is applied to a surface charged membrane, generating electroosmotic flow through the membrane’s pores. This work provided a characterization of the specific energy costs (SEC) of electroosmotic flow and gave insight into how electrofiltration may be adopted by full-scale filtration processes.
Lastly, Vinny studied a novel piezoelectric PZT membrane employed for municipal wastewater treatment. When stimulated, piezoelectric materials (including the microporous PZT membrane) transform electrical signals into a physical vibrations. This effect allows for the production of ultrasonic vibrations from within the PZT membrane during active filtration. This work focused on characterization of the piezoelectric response from PZT membranes and evaluation of the effects of ultrasonic vibration on wastewater filtration.

Dr. Anderson is currently a consulting engineer for Strand.
