Flexible Desalination Systems for Variable Salinity Sources
Variable salinity desalination applications are becoming more abundant. The Expeditionary Unit Water Purifier Generation 1 was used to evaluate the practical aspects of converting a singlestage seawater system with energy […]
The Round Mountain WTP: A Brackish Water RO Facility for Water Self-Reliance and Regional Salinity Management
This paper and presentation address the permitting issues and cost evaluation for an inland brackish water treatment plant. The solution to these challenges created a successful model for the region […]
Evaluation of Virus Removal Capabilities of Membrane Bioreactor (MBR) Systems in a Full Scale Water Reclamation Facility in Nevada
Many water utilities ask why stringent UV disinfection requirements are in place since reclaimed water pathogen limits are mainly met through MBR alone. The energy use and associated cost for […]
Application of Universal MF/UF Membrane Skid in a Full Scale Wastewater Reclamation Plant-Challenges and Future
During the last decade, the water industry has observed the dramatic increase in the application of Microfiltration (MF)/Ultrafiltration (UF) membranes for water and wastewater treatments. According to the latest report […]
Piloting Alternative Technologies for Indirect Potable Reuse in Florida
As growing demand taxes existing drinking water supplies and rising wastewater effluent standards lead to more advanced wastewater treatment, planned indirect potable reuse is becoming a feasible scenario for more […]
Pretreatment of High TOC Surface Waters to Minimize DBP Formation after Membrane Filtration
Low-pressure membrane (LPM) technologies are becoming increasingly common in drinking water treatment, especially for the removal of disinfection byproduct (DBP) precursors. Removal of DBP precursors by LPMs requires pretreatment that […]
Comparison of Pilot and Full Scale Ion Exchange Pretreatment to Microfiltration Membranes
Microfiltration membrane fouling can occur through the accumulation of particles, organic matter and biological growth. Depending on the surface water source and the treatment prior to water contacting the membrane, […]
The Influence of Beach Well and Deep Ocean Intakes on TEP Reduction in SWRO Desalination Systems, Jeddah, Saudi Arabia
Transparent expolymer particles (TEP) are believed to be a key organic compound that leads to membrane biofouling in SWRO systems. The sticky nature, high surface reactivity and micro-gel character of […]
Sheyenne River Unique Water Quality Challenges: A Comparative Pilot Study of Three MF/UF Membranes
The City of Fargo Water Treatment Plant (WTP) recently piloted GE submerged ZeeWeed 1000, Siemens encased MemCor L20N, and Pall encased UNA-620A membranes for its new 15 million gallons per […]
Operational Optimization of a Surface Water Membrane Facility; Considering Pretreatment, Post-treatment, and Associated Costs
The design, construction, and start-up of a surface water membrane treatment facility, while difficult, were not the last challenges faced by operational staff. Daily operation of the individual system components, […]
