Quincy Water Reuse Utility TDS Control
The paper describes the new Q1W Utility that will integrate its industrial and municipal wastewater treatment systems in Quincy, Washington. At the core of the utility are new membrane ultrafiltration […]
Membrane Bioreactors (MBR) and Reverse Osmosis (RO) for Leachate Treatment
This paper describes four pilot studies that were conducted to evaluate the Membrane bioreactor (MBR) process for leachate treatment. Both hollow fiber and cross-flow systems from several vendors were evaluated. […]
Phasing and Pretreatment Considerations for Clifton Water District’s Media Filter to Membrane Filter Conversion
This paper discusses the phasing and pretreatment considerations for the Clifton Water District (CWD) project to convert the 12 MGD of granular media filters at its drinking water treatment plant […]
Addressing the Unique Constraints of Small-Scale Ultrafiltration Systems
Recent trends in membrane system design, such as the open-platform system concept, are discussed in this paper. In addition, the results of a pilot study are shown which demonstrate the […]
Alternative Determination of the QCRV from Challenge Test Results
This paper describes an evaluation of data using simple descriptive statistics and knowledge of the limitations of test methods to reach a logical decision and is applied to a specific […]
Selective Removal of Sodium And Chloride? Mono-Valent Selective Ion Exchange Membrane for Desalination and Reuse Enhancement
This paper will provide a synopsis on technologies that are capable of selectively removing sodium and chloride ions along with experiments to examine newly development monovalent salt selective membrane elements.
Pressure Retarded Osmosis as Energy Recovery for Reverse Osmosis Desalination: Module-Scale Modeling & Specific Energy
