A New Tool for Measuring Biosolids Floc Strength
The ability to measure sludge network strength is important in sludge dewatering applications because it can be used to determine optimum polymer dose for conditioning to achieve …
Workshop on Microbial Source Tracking in Water
The drinking water and wastewater industries are interested in developing a better understanding of sources of fecal contamination. Microbial source tracking (MST) offers the …
Understanding Factors Affecting Polymer Demand for Thickening and Dewatering
Polymer demand varies considerably for different digestion processes as well as the same digestion processes at different locations and the reasons for these differences are not …
Membrane Bioreactors for Anaerobic Treatment of Wastewaters (Phase II)
Anaerobic biological treatment systems can offer a number of advantages over their aerobic counterparts. The operational costs associated with anaerobic systems are typically lower …
State of the Science
The literature review described in this report is part of a larger research project to assess STU performance with respect to treatment of important wastewater constituents. The …
Silver Biotic Ligand Model (BLM)
The biotic ligand model (BLM) is a computational tool that may be used to predict toxic effect levels of metals, including Ag. The BLM considers the effect of site-specific water …
Development of Practical Methods to Assess the Presence of Bacterial Pathogens in Water
The objective of this project was to develop and evaluate a practical technique to indicate the probability of the presence of bacterial pathogens in receiving waters. A practical …
Decentralized Stormwater Controls for Urban Retrofit and Combined Sewer Overflow Reduction, Phase 2
Phase 1 of this project demonstrated the technical feasibility of using decentralized stormwater controls in urban areas for retrofits and controlling combined sewer overflows. …
Development of a Protocol for Risk Assessment of Microorganisms in Separate Stormwater Systems
Recent research has shown that the concentrations of microbial indicator organisms (e.g., fecal coliforms) in stormwater may be quite high. However, studies have not clearly …
Ultrasonic Destruction of Surfactants
This research focused on the use of sonication to destroy surfactants and surface tension properties in industrial wastewaters that affect traditional water treatment processes. We …
