Anaerobic Membrane Bioreactors for Sustainable Wastewater Treatment
Sustainable water management is increasingly important for utilities and is driving efforts to reduce energy consumption and residuals production in domestic wastewater (DWW) treatment without...
Performance Dynamics of Trace Organic Chemicals in Onsite Treatment Units and Systems
The purpose of this work is to improve our understanding regarding presence and attenuation of TOrC in onsite wastewater systems. A full-scale septic tank and sequencing batch membrane bioreactor...
Development of Protocols and Methods for Predicting the Remaining Economic Life of Wastewater Pipe Infrastructure Assets: Phase 1 (Development of Standard Data Structure to Support Wastewater Pipe Condition and Performance Prediction)
Accurate prediction of wastewater pipe structural and functional deterioration plays an essential role in the utility asset management process and capital investment planning. The key to...
Source Separation and Treatment of Anthropogenic Urine
Anthropogenic urine, although only 1% of domestic wastewater flow, is responsible for 50-80% of the nutrients and a substantial portion of the pharmaceuticals and hormones present in the influent...
Improving the Efficacy of Wastewater-Polishing Reed Beds
This title belongs to WERF Research Report Series.
The purposes of the project were to:
a) determine species of microbiological contaminants entering, residing, and...
Developing Better Indicators for Pathogen Presence in Sewage Sludge
Today, more than eight million tons of biosolids are generated annually for land application nationwide. These biosolids contain beneficial plant nutrients, soil conditioners, and may contain...
Striking the Balance between Nutrient Removal in Wastewater Treatment and Sustainability
This study focuses on sustainability impacts as wastewater treatment plants implement treatment technologies to meet increasingly stringent nutrient limits. The objective is to determine if a...
Guidance Manual for Separation of Graywater from Blackwater for Graywater Reuse
Increasing efforts in water conservation have prompted home and business owners to learn more about water reuse. One reuse application of interest is separating graywater (all wastewater excluding...
Development of Design Criteria for Denitrifying Treatment Wetlands
Subsurface wetlands are well suited for on-site applications because they provide odor and vector control and they mitigate public access issues (U.S. EPA, 1993). Artificial subsurface wetlands...
Phosphorus Removal Potential Using Biogenic Iron Oxides
Biogenic iron oxides produced by circumneutral iron-oxidizing bacteria were evaluated for phosphate removal. Traditional batch equilibrium experiments were coupled with bench-scale flow through...
