Abstract: The objective of this study is to evaluate the significance of four structural design features (inlet configuration, weir location, intermediate baffle existence, and sludge draw-off location) and their interactions on the ...

Abstract: Rainfall was found to affect the performance of an overland flow land treatment system used for the treatment of municipal wastewater. However, effluent

Abstract: The principal objective of this study was determination of the response of a laboratory-scale vapor-phase flow-direction-switching biofilter to loading changes associated with normal operations such as lunch breaks, overnight ...

Abstract: Transient loading of vapor-phase biofilters may result in exceedence of the local reaction or mass transfer capacity of the inlet region. In such cases, higher concentrations of contaminants are carried deeper into the bed ...

Abstract: Identification of bacteria that can utilize a wide range of nitroaromatic compounds will allow development of more effective biological treatment methods in industrial wastewater treatment processes and environmental ...

Abstract: Controlled precipitation of struvite from postdigestion, sludge lagoon supernatant was studied using a pilot scale fluidized bed reactor (FBR). The process effectively and rapidly removed struvite constituents from the ...

Abstract: Experiments were conducted for the evaluation of a continuous flow conductimetric method that measures the inorganic nitrogen compounds ammonia (NH

Abstract: A pilot-scale compost biofiltration system was operated at a gasoline soil vapor extraction site in Hayward, Calif. for one year. The media was composed of equal volumes of compost and perlite, a bulking agent. Supplements ...

Abstract: The kinetics of struvite (MgNH
