Design of Biomass-Derived Activated Carbons for Adsorption of Uranium from Mine Tailings

Description: Northwestern New Mexico is home to hundreds of abandoned uranium mines and home to forests that produce an excess of woody biomass residues that present a wildfire hazard. These residues can be used to produce activated carbons, high surface-area materials that can adsorb contaminants out of air and water. The goal of this project…

Calculation of Engineering Parameters for Continuous Flow Hydrothermal Liquefaction Reactor

Description: Hydrothermal liquefaction (HTL) of algae in a continuous flow reactor to produce bio-crude oil requires careful control of flow rates and heating rates to allow sufficient reaction time while preventing the formation of clogs. In the pilot scale HTL reactor system, the original design parameters allow for flow rates up to 250 mL/min. The…

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,…
