Municipal Solid Waste Incinerator Testing and Evaluation
…the similarities, the experience gained at U.S. incineration plants may be applicable to the Taiwanese plants. This paper will discuss U.S. experience of mass-fired MSW incinerator testing and performance evaluation….
Evaluation of Primary Sedimentation Tanks Performance By Integrating Mathematical Modeling With Field Testing
…modeling with field-testing. A high accuracy clarifier model (HACM) was used to simulate the flow field in the PSTs. A new approach for estimating the settling velocity distribution of the…
How Much Can My Plant Treat? Using Models and Stress Testing to Determine Plant Capacity
…data for the activated sludge simulator, BioWin. In addition, a secondary clarifier stress test was performed and used to validate the secondary clarifier model, 2DC. The calibrated models were used…
Nitrification Rate Testing using WERF*s High F/M Protocol:
…the City of Atlanta used the High F/M method developed by WERF to determine nitrification rates for these studies. Along with conducting these tests, many problems arose including nitrite monitoring,…
Monitoring Well Siting: Crucial Decisions
…ground water sampling program. Many sampling events can reveal misleading ground water information because the well siting is inconsistent with the project data requirements. As a consequence, every well installation…

Innovative LiDAR scanning helps utilities above and below
New ways to use laser technologies and 3D imaging for increased understandingVerification of the Fate of a Volatile Organic Compound in Activated Sludge
The fate of the volatile organic compound, 1,4-dichlorobenzene (DCB) was examined in a bench-scale activated sludge system. A shift in removal mechanism, from stripping to biodegradation, was observed at different…
