Brewer receives $395,332 from NASA for NDMA adsorption research

The evaluation of low-level N-Nitrosodimethylamine (NDMA) in water has become a recent concern for the U.S. Environmental Protection Agency. Many states including New Mexico and California have reported NDMA contamination in drinking water. Activated carbon created from pecan shells may provide a new alternative to UV photolysis for the treatment of NDMA-contaminated water. The aim of…

Developing Liquid Scintillation Counting Method for Quantification of NDMA at Ultra-Low Concentrations

Description: As part of the ongoing project with NASA White Sands Test Facility on removal of N-nitrosodimethylamine (NDMA) from groundwater, this project focuses on the development on a new analytical method to measure the NDMA at the part per trillion levels needed for this scenario. By using 14C-labeled NDMA in synthesized solutions, on-campus and timely…

Reducing Sulfuric Acid in Gases from Anaerobic Digestion

Description: Dairy manure can be used to produce electricity through anaerobic digestion of wet manure/manure liquids followed by combustion of the biogas. One major challenge to producing electricity for dairies in certain regions is the corrosion of electrical motors by the sulfuric acid gases in the biogas due. Several sulfuric acid mitigation technologies exist and…

Brewer and Foudazi receive $224,243 from WRRI

Dr. Catherine Brewer has been funded by the Water Resources Research Institute (WRRI) for her proposal entitled, “Biochar for Desalination Concentrate Management.”  Total funding provided for this project is $74,377. Alternative Waters Problem: Disposal of concentrate from brackish water desalination is limited by concerns of salt leaching into and contaminating surface and ground waters. These concerns, and…

Improvements to Lab-Scale Mutliple Effect Distillation Unit

Description: A previous research project enabled the fabrication and testing of a lab-scale multiple effect distillation (MED) unit. The unit is intended to study scaling and heat transfer as functions of temperature and pressure during desalination of brackish ground water. Early testing of the unit indicated needs for greater heat energy supply, better leak prevention,…

Hydrothermal Liquefaction of Algae for Biofuels

Description: Production of transportation fuels from microalgal biomass is markedly different from production of fuels from lignocellulosic biomass due to the differences in feedstock biochemical composition and optimal conversion processing conditions. Completion Objectives: Compare and contract lignocellulose and microalgal biochemistry and production. Describe desirable properties of solid and liquid fuels for power and transportation. Compare…

Optimizing Pecan Shell Activated Carbons for NDMA Adsorption

Description: Groundwater at the NASA White Sands Test Facility is contaminated with low levels of N-nitrosodimethylamine (NDMA) from past rocket fuel tests. The current treatment method is UV-photolysis, however, promising early results indicate that treatment with activated carbons may be more cost-effective. The purpose of this project with to test the limits of pecan shell…
