20110089107 | INTIMATE COUPLING OF PHOTOCATALYSIS AND BIODEGRADATION IN A PHOTOCATALYTIC CIRCULATING-BED BIOFILM REACTOR - Systems and methods are provided for intimately coupling advanced oxidation process (AOP) with biodegradation for the treatment of contaminated water. The system comprises a particulate bed having carrier particles that have a microbial film effective for biodegrading contaminants in the contaminated water. An advanced oxidation reagent is irradiated by a radiation source to provide an advanced oxidation reagent effective for oxidizing recalcitrant compounds in the contaminated water to form biodegradable byproducts. The microbial film is effective for biodegrading the byproducts substantially immediately after they are produced. The carrier particles are also effective for protecting the microbial film from the radiation and/or the recalcitrant compounds. | 04-21-2011 |
20110143224 | BICARBONATE AND CARBONATE AS HYDROXIDE CARRIERS IN A BIOLOGICAL FUEL CELL - The present invention relates generally to a process that helps alleviate the pH gradient between anode and cathode compartments in any biological fuel cell or electrolytic cell configuration in which a pH gradient between anode and cathode is limiting the voltage efficiency. By providing acid to the cathode compartment in the form of CO | 06-16-2011 |
20110300455 | Micro-Sized Microbial Fuel Cell - A microbial fuel cell includes an anode portion having an anode and a cathode portion having a cathode. The anode is configured to support an electrically conductive biofilm matrix. A cation exchange membrane is positioned between the anode and the cathode. The anode portion and the cation exchange membrane define an anode chamber having a volume of between about 1 μL and about 100 μL and configured to receive an anolyte. The cathode portion and the cation exchange membrane define a cathode chamber having a volume of between about 1 μL and about 100 μL and configured to receive a catholyte. The microbial fuel cell is configured to achieve a Coulombic efficiency of at least 30% and/or a power density of at least of 4.7 μW/cm | 12-08-2011 |
20120082869 | Microbial Electrolytic Cell - System and methods for efficiently capturing hydrogen gas from a microbial electrolytic cell. Certain aspects of the invention describe microbial electrolytic cells in which the cathode is located above the anode and proximal to a fluid level and a gas headspace in the single-chamber microbial electrolytic cell. In other aspects, the invention relates to improved and high volumetric production rate of hydrogen gas effected by increasing the geometric surface area of the electrodes. Combinations of these aspects also are contemplated. | 04-05-2012 |
20130115684 | METHODS AND SYSTEMS FOR REDUCTION OF HALOGENATED COMPOUNDS - Methods and systems for dehalogenating organohalides are disclosed. In one respect, the systems can generate hydrogen in an electrolysis cell and supply the hydrogen to anaerobic dehalogenating bacteria to decontaminate organohalides at a contamination site. | 05-09-2013 |
20130345990 | TOOL FOR OPTIMIZING CHLORINATED-SOLVENT BIOREMEDIATION THROUGH INTEGRATION OF CHEMICAL AND MOLECULAR DATA WITH ELECTRON AND ALKALINITY BALANCES - A prediction and assessment tool for bioremediation performance based on a comprehensive understanding of the link between chemical flow and microbial community interactions includes linking molecular microbial ecology data with electron and alkalinity balances to make it possible to understand dechlorinating microbial communities and their metabolic processes. The interactions of biological processes and site mineralogy result in changes to alkalinity and pH that can lead to incomplete reductive dechlorination resulting from suboptimal pH. Understanding these interactions allows for strategies to predict expected bioremediation outcomes and/or to mitigate incomplete reductive dechlorination. | 12-26-2013 |
