Research

Development of biological and physicochemical processes for water and wastewater with focus on treatment of industrial streams containing energetic compounds and nutrients. Bimetal catalysis for the reductive degradation and mineralization of organic pollutants. Surface modification of nanofibrils and biomaterials for the adsorption of ionic substances including recovery and reuse of ionic nutrients.

Sustainable practices at industrial facilities nutrient recovery and reuse. Waste valorization for generation of renewable resources. Reductive and oxidative conversion of energetic compounds such as RDX, Nitroglycerine, Nitrocellulose, NQ, DNAN, hexanitrohexaazaisowurtzitane (CL-20) in industrial production wastewater streams to carbon dioxide, nitrate and ammonia for the production of algal biomass.

Algae biomass growth and harvesting for biofuel production. Utilization of industrial wastewater as growth media for biomass generation. Investigation of cost effective methods of algae harvesting and concertation and their subsequent use for production of renewable energy via algal oil extraction and upgrade to biodiesel or biogas generation by anaerobic digestion.


Recovery of nutrients from inedible plant material (Life Support Systems for Space Travel, NASA): Determination of the biodegradation rates and waste treatment requirements of the inedible part of the biomass (stem and leaves). Waste treatment is part of a life support system where materials are continuously recycled and re-used. Total recycle of materials is extremely important for extended space travel and planet missions (e.g. a mission to Mars) where supplies cannot be routinely transported from the earth

Investigation of RDX and PAX-21 Propellant Treatment Methods: Cost analysis of treatment processes for the decontamination of RDX contaminated groundwater, and investigation of the biodegradability of the post hydrolysis products of groundwater treated with hydroxide solutions. Alkaline hydrolysis of PAX-21 propellant in batch reactors. Development of Large Volume, Ambient Pressure, Non Thermal Diffuse Plasma Reactor for Destruction of Airborn Environmental Contaminants in Advanced Life Support Systems: An investigation on the effectiveness and efficiency of a novel, non-thermal diffuse plasma technology for the destruction of environmental air contaminants in space applications. The plasma characteristics, plasma chemistry, contaminant destruction efficiency and reaction kinetics for various compounds expected to be present in advance life support environments are studied

Investigation of a Novel Capillary Non-Thermal, Ambient Pressure Plasma for Cleaning of Aluminum Surfaces: Development of a non-thermal diffuse plasma technology for the cleaning and decontamination of aluminum surfaces. Experiments are being conducted to determine the plasma characteristics necessary for the destruction of organic substances deposited on aluminum surface, to identify the proper plasma gases for effective removal, to determine the role of the surface on destruction efficiency, and to evaluate surface changes due to plasma irradiation

Use of Capillary Non-Thermal, Ambient Pressure Plasma in Decontamination of Water Recovered from Vehicle Exhaust: Investigate the potential role of diffused non-thermal plasma in the treatment of water condensate recovered from the exhaust of the diesel engines of Hum-Vee and other vehicles. One treatment scenario involves pre-treatment of the combustion mixture in order to increase the efficiency of combustion and thus reduce the concentration of undesirable organic products in the diesel exhaust gases. The second treatment scheme focuses on plasma treatment of the exhaust gases prior to condensation. Finally, a treatment system is investigated which treats the aqueous solution obtained from the condenser by continuously passing the vapors produced from the liquid phase through a plasma reactor in a closed loop configuration
