Abstract: The invention relates to novel Methylobacterium species that are capable of degrading nitroaromatic and nitramine compounds. Compositions, kits and methods of using the Methylobacterium species for the degradation of nitroaromatic and nitramine pollutants are provided. More specifically, compositions and methods for the degradation or bioremediation of nitroaromatic and nitramine explosives and explosive residues are provided.

Abstract: Disclosed are methods, devices and apparatus for bioremediation of mixed waste aquifers, based on a synergistic combination of reductive treatment using zero-valent iron and anaerobic biotransformations. Also disclosed are methods for in situ and ex situ remediation of groundwater and wastewater via these iron-bacterial compositions in a variety of devices including batch reactors, permeable and semipermeable reactive barriers, flow-through reactors, fluidized bed reactors, and sediment tanks.

Abstract: A system and method is provided that predicts operational parameters for all unit operations in water treatment plants or the like. Initial training with historical operations data, for example, allows the system and method to develop equations that can in turn predict the present and future performance of the plant in real time. In addition, the system and method can control operations of the plant in real time. The system improves the performance of the plant to meet predetermined subpoints of various parameters. For example, the predetermined subpoints can be used to enable the plant to meet regulatory needs while controlling for other parameters such as cost, chemical fees, flow rates and power consumption. The system and method include a non-linear predictive model for turbidity. The system considers the influent water quality and analyzes treatment options available to predict the dose of various chemicals required to get desired treatment.
