Abstract: A method and apparatus for treating residuals or waste streams from a plant, such as a drinking water treatment plant. The method includes the steps of obtaining plant residuals or waste streams from a water treatment plant and irradiating the plant residuals or waste streams using microwave radiation from a microwave source. The method also includes the step of drying the plant residuals or waste streams to a predetermined moisture, volume, or weight content reduction and disposing of the same.

Abstract: A rapid and continuous separator or equilibrator to separate a gas from a liquid includes a venturi and injector, a mixer and a free overfall stream to separate a gas from a liquid. The injector introduces a carrier medium into the liquid which provides a reservoir for the gas to diffuse into as the liquid and carrier make a single transit through the apparatus. The separator was developed to enable real-time estimation of methane concentrations in ground water during purging. Real-time monitoring allows evaluation of trends during water well purging, spatial trends between water wells, and temporal comparisons between sampling events. These trends may be a result of removal of stored casing water, pre-purge ambient borehole flow, formation physical and chemical heterogeneity, or vertical flow outside of well casing due to poor bentonite or cement seals. Real-time information in the field can help focus an investigation, aid in determining when to collect a sample, save money by limiting costs (e.g.

Abstract: A composition includes an aqueous solution including at least one fluorinated organic compound; and a reaction product of a source of iron(II) and a source of sulfite in the presence of water and molecular hydrogen. A method of making a catalyst includes reacting a source of iron(II) and a source of sulfite in the presence of water and molecular hydrogen. The water may include less than or equal to 1 weight percent dissolved molecular oxygen. The catalyst may be used for degrading fluorinated organic chemicals in aqueous media.

Abstract: The invention relates to a device for measuring, in near-real-time, the level of black carbon, brown carbon, organic carbon, total carbon and CO2 in air. The device also provides for a direct calculation of aerosol angstrom coefficient as well as estimation of emissions rates of black carbon or brown carbon from nearby combustion sources.

Abstract: The invention relates to a sample device that allows for simultaneous analysis of multiple liquid samples (e.g., drinking water samples). More specifically, the sample device is adapted for use with a mobile water analyzer, the sample device including an upwardly open receptacle divided into a plurality of separate upwardly open compartments separated by dividing walls. Each of the compartments is configured to contain a separate water sample, and the sample device is adapted to receive the inlet opening of a removable test element of a mobile water analyzer.

Abstract: A real-time system and method for personal air pollution exposure and inhaled dose management is described. A personal device (e.g., smartphone) determines personal exposure and inhaled dose metrics (e.g., daily accumulated dose), and compares daily histories of these metrics with personal health histories (e.g., self-reported daily asthma symptoms/inhaler use) to provide notifications when adverse health effects (e.g., asthma exacerbation) are likely to occur. The system notifications provide a personalized exposure/dose management tool by recommending behavioral changes to reduce exposure/dose (e.g., change time-location, time-physical activities, building operation). These behavioral changes are then used by the system to modify the real-time exposure and dose determined by the system.
