Abstract: Cadmium ion-selective microelectrodes and carbon fiber mercury film microelectrodes were fabricated and compared in this research. In order to determine whether either microelectrode could be used in biofilm microenvironmental ...

Abstract: The application of surfactants for the bioremediation of sites contaminated with polycyclic aromatic hydrocarbons has been widely reported, because they are known to increase PAH solubility and desorption, thereby enhancing ...

Abstract: The influence of supplemental acetate on in situ bioremediation for the removal of dissolved polycyclic aromatic hydrocarbons (PAHs) in groundwater was evaluated in laboratory sand columns. Sand columns, inoculated with a ...

Abstract: This paper presents the study results for a novel stabilization/solidification (S/S) process for high mercury wastes (Hg >260 ppm). In this study, a low-cost powder reactivated carbon (PAC) was used to stabilize mercury ...

Abstract: The effect of Acid Orange 7 (AO7) (C.I.15510), an azo dye commonly used in textile, pharmaceutical, food, and cosmetic industries, on the nitrification process is studied using completely stirred tank reactors (CSTR) and ...

Abstract: The effects of temperature on the rheology of five municipal wastewater sludges was examined using a Stormer rotational viscometer. The sludges had total solids concentrations ranging from 2.0 percent to 6.6 percent by ...

Abstract: This study investigated the spatial distribution of biofilm extracellular polymeric substances (EPS) with depth in biofilms. Heterotrophic biofilms were grown in a rotating drum biofilm reactor fed with synthetic wastewater ...

Abstract: An aerobic fluidized bed reactor process with internal media cleaning to control attached biomass thickness was developed. Biomass control was achieved by the periodic creation of a turbulent zone within a specially designed ...
