Evaluating How Nanofiltration Stacks up to Other Non-Conventional Technologies for a Florida Surface Water AWS
An evaluation of treatment alternatives using the Judge Farms Reservoir as a source water was conducted to determine the technical and economical viabilities of a potable water treatment facility. Three […]
The Impacts of Potential Controlling Parameters on the Degree of Nitritation in a MABR Treating High Strength Wastewater
This study presents the shortcut nitrification in a membrane aerated bioreactor (MABR) treating high strength nitrogen waste stream. The utilization of MABR has advantages of bidirectional control of oxygen (O2) […]
Strategies and Options for Replacement of MF/UF Membranes and Upgrading Plant Performance
Microfiltration (MF) and ultrafiltration (UF) as applied on drinking water and wastewater has evolved significantly over the past 30 years. While research existed for some time, the technology started gaining […]

Ocean Plan Amendment Compliance Carlsbad Desalination Plant Catches the First Wave
The Claude “Bud” Lewis Carlsbad Desalination Plant (CDP), pictured in Figure 1, has been operating for nearly 3 years, producing approximately 50 million gallons per day (MGD) to meet 10 […]
Established Practices, Innovative Design, and New Products: A New Generation of Ultra High Pressure Desalination
In common parlance, reverse osmosis (RO) is often described as removing salt from water. In practice however, these processes squeeze water from a salt solution resulting in concentrate to be […]
Application of Two-Stage Ultrafiltration for High Water Recovery and Minimal Waste Discharge in Big Timber, MT
A two-stage ultrafiltration system designed, built, and commissioned for the City of Big Timber, MT, is described. After a thorough review of technology options, while determining how to bring their […]
Brine Minimization Using Closed Circuit Reverse Osmosis (CCRO)
Marine Corps Air Ground Combat Center (MCAGCC) Twentynine Palms is in the Mojave Desert in California and is one of the largest military training areas in the nation. MCAGCC relies […]
Pulse Flow RO for Water Reuse Applications – Design Considerations
Water scarcity and population growth create increasing pressure on natural water sources and require the development of new, sustainable water sources. As technologies gradually improve, reusing effluent from municipal wastewater […]
Cherokee Metro District’s TDS Reduction Facility: First MBR and High Recovery RO Reuse Facility in U.S.
Cherokee Metropolitan District (CMD) outside of Colorado Springs, CO currently operates a 4.8 mgd maximum month flow water reclamation facility (WRF) with sequencing batch reactors (SBRs) and ultraviolet disinfection. The […]
