Use of Enhanced Biological Phosphorus Removal for Treating Nutrient-Deficient Wastewater
Anaerobic/aerobic (AnA) and completely aerobic (CA) laboratory-scale sequencing batch reactors operating on an acetate- and casamino acids-based synthetic wastewater were used to …
Strategies for Sustainable Water Resource Management
Integrated water resource management has been discussed since at least the Civil War; yet, there is still no integrated framework for sustainably managing water. Recognizing this …
Evaluation of WET Testing as an Indicator of Aquatic Health in Effluent-Dominated Streams
This project evaluated the quality of data needed to determine relationships between chronic Whole Effluent Toxicity (WET) test results and in-stream biological condition. A data …
Characterizing Mechanisms of Simultaneous Biological Nutrient Removal During Wastewater Treatment
Simultaneous biological nutrient removal (SBNR) is the removal of nitrogen and/or phosphorus in excess of that required for biomass synthesis in biological wastewater treatment …
Factors Affecting the Performance of Primary Treatment in Onsite Systems
Approximately 23 percent of the estimated 115 million occupied homes in the United States are served by onsite wastewater systems. The vast majority of onsite wastewater treatment …
Navigating the TMDL Process
Narrative water quality criteria are an integral component of States water quality standards but they pose special problems when incorporated into the TMDL process. The TMDL …
Identifying and Controlling Odor in the Municipal Wastewater Environment, Health Effects of Biosolids Odors
This report deals with whether the experience of odors, i.e., odors as sensations, from biosolids at wastewater treatment plants (WWTPs) causes illness. There exists no repository …
Acclimation of Nitrifiers for Activated Sludge Treatment
Nitrification kinetics were evaluated in bench-scale batch reactors fed with a synthetic wastewater containing approximately 1,000 mg ammonia-nitrogen (NH3-N)/L operated at 5, 10, …
Evaluating Endocrine Disruption in Receiving Waters
In recent years, concerns have been raised that low concentrations of chemicals may alter the normal functions of the endocrine system, resulting in potentially significant adverse …
Whole Effluent Toxicity Testing
Under the National Pollution Discharge Elimination System (NPDES), many municipal and industrial wastewater treatment facilities must perform Whole Effluent Toxicity (WET) Testing. …
