Application and Optimization of the Galvano-Coagulator Process To Heavy Metal Waste Streams
The galvano-coagulator is a technology developed in the former Soviet Union in the 1980s. The major feature of the technology is that it appears to be an effective process in hexavalent chromium...
Characterizing Phosphorous in Biosolids, Commercial Fertilizers, and Manures (phase 1)
This research:
- Evaluated the forms, solubilities, and bioavailabilities of phosphorus (P) in biosolids, commercial fertilizers, and manures. Data suggests that some biosolids can be...
Best Practices for the Treatment of Wet Weather Wastewater Flows
During wet weather events, separate and combined wastewater collection systems deliver substantial amounts of storm water runoff to wastewater treatment plants. Often these flows...
Membrane Bioreactors for Municipal Wastewater Treatment
Recent technical innovations and significant cost reductions have sharply increased the potential for using Membrane Bioreactor (MBR) technology in municipal wastewater treatment. MBR technology...
Effluent Limits for Fluctuating Discharges: Phase II - Alternate Frameworks for Water Quality Criteria
This research evaluated appropriate methodologies to calculate water quality criteria for exposure concentrations that vary in frequency, magnitude and duration. We reviewed over 30 toxicological...
Assessment of Technologies for Screening, Floatable Control, and Screenings Handling
Screening and floatable controls are used at wastewater treatment, sanitary sewer overflow (SSO) and combined sewer overflow (CSO) locations. Screening is a preliminary treatment step and...
Developing Protocols for Measuring Biosolids Stability
The general goal of this project is to validate test protocols that are commonly used to assess the stability of various biosolids products, and to specify a standard for each test method. Toward...
