Biological Wastewater Treatment and Operations Training in Argentina
A wastewater treatment process at a potato processing plant located in Argentina was experiencing continuous upsets with their activated sludge treatment system. A hands-on training program was implemented to teach operators to monitor and control the two existing biological treatment processes consisting of a low rate anaerobic wastewater treatment pre-treatment and an activated sludge treatment system.

Bench Scale Testing of Advanced Oxidation for MTBE
The Merced County of Environmental Health office ordered a gas station located in Los Banos, California to mitigate a plume of MTBE. To mitigate the MTBE in groundwater, an advanced oxidation system was proposed for the site. A pilot test was performed to assess the impact of ozone on naturally occurring chromium in soil at the site.
