My research interests center around process
development for water and wastewater treatment systems, including
mathematical modeling and optimization. More recently I have applied
these mathematical techniques to urban runoff and stormwater issues.
Recent experimental work has focused on estimating oxygen transfer in
activated sludge plants, including high purity oxygen plants. Field
studies are being conducted at plants to ascertain fine pore diffuser
fouling rates and develop cleaning techniques. This work is coupled with
theoretical and laboratory scale work to better determine the effects
of surfactants on oxygen transfer through dynamic surface tension
measurements.
A recently completed project involves the use of wastewater reclamation.
We constructed and operated a 40L/min. pilot plant at the Grass Valley
Treatment Plant in Lake Arrowhead, CA. The pilot plant included
denitrification, ozonation, filtration, and two membrane treatment
steps. The plant demonstrated virus removal well in excess of California
State guidelines. The plant met other treatment objectives as well.
In the past several years, we have worked extensively with stormwater
issues. We developed a model to predict pollutant emissions to Santa
Monica Bay from non-point sources. We have also developed several
non-point source pollutant controls and evaluated several commercially
available units. Our largest current project is evaluating first flush
runoff from California highways. |
