Title: 00-CTS-3, Tools for Rating the Capacity of Activated Sludge Plants
Description
The goal of this project was to develop protocols that integrate uncertainty and water quality considerations into the design process for activated sludge treatment plants. The report includes a review of activated sludge process models, a statistical primer, and the two statistical tools developed during this project: 1) a spreadsheet for identifying outliers in historical wastewater records using multivariate statistical methods; and 2) parameter distributions representing the uncertainty in activated sludge model parameters. The report also includes two detailed examples that demonstrate the use of the protocols. Using these protocols should help engineers avoid making overly conservative assumptions and estimates in treatment plant design. Published by WERF. 160 pages. CD-ROM.

Title: 00-PUM-7, Full Cost Accounting Protocol for Biosolids Management
Description
This report details a methodology to determine the full costs of biosolids management programs including O&M, assets, and indirect costs. This information can help biosolids managers identify areas for cost savings and examine the results of operations or other changes. The approach was also designed to be flexible, and applicable to subsets of a complete biosolids treatment train. The project team, with input from many wastewater utilities, developed a workbook and spreadsheets that provide a logical framework for performing a full cost analysis. The spreadsheets can be applied with appropriate modifications to address site-specific factors. These interactive worksheets are available on CD-ROM and are free to WERF subscribers.

Title: 01-CTS-18UR, LCAMER - An Assessment Tool for Managing Cost-Effective Energy Recovery From Anaerobically Digested Wastewater Solids
Description
The Life Cycle Assessment Manager for Energy Recovery (LCAMER) is a spreadsheet-based tool which enables wastewater treatment plant owners and engineers to make informed decisions on the feasibility of recovering energy from anaerobic digestion of wastewater solids. Using a life cycle assessment approach, which incorporates factors such as equipment lifetime and the cost of borrowed money, users can compare the payback periods or internal rates of return for anaerobic digestion processes (mesophilic, thermophilic, temperature-phased); gas pretreatment processes (hydrogen sulfide, siloxanes and carbon dioxide); and energy recovery processes such as boilers, engine-generators, turbines, fuel cells and direct drive engines.

Title: 04-CTS-1a, Collection System Ventilation
Description
This study used extensive field studies in the U.S. to look at the strengths and weaknesses of current ventilation models in order to develop future modeling tools. The field experiments resulted in a large database of measured ventilation and related parameters to characterize ventilation in full-scale gravity sewers. The field data were used as input to three current models to evaluate their accuracy compared to the measured field data and the strengths and weaknesses of each model were assessed. Observations from the study were used to develop a concept for an improved ventilation model based on conservation of momentum equations in connected collection system components.

Title: 04-HHE-3, Microbial Risk Assessment Interface Tool and User Documentation Guide
Description
Designed for water and wastewater utility engineers and managers with basic knowledge of quantitative microbial risk assessment. Users specify the pathogen that the input data correspond to, additional or incremental wastewater treatment that occurs prior to human exposure, and the pathogen's route of human exposure. The tool then recommends a static (individual-based) or dynamic (population-based) risk characterization methodology based on the input data and the user's model parameter selections. An estimate of the potential public health risk associated with the specific pathogen and exposure scenario is made via numerical simulation with results presented graphically. The Microbial Risk Assessment Interface Tool is used as an open source Mathcad worksheet.
