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 effectiveness of ay Ultrafiltration (UF) membranes available on the market. Finally, case studies of challenging small-scale systems in Utah and Oregon are discusse...
The Art of Retrofitting UF/MF Systems: A Comparison of Strategies, Costs, and Results
As UF/MF membrane modules reach the end of their useful life, end-users have more options than ever before to either purchase direct module replacements or upgrade the system. Recent trends and advancements in membrane materials, configuration, and process design have improved the performance of low pressure membrane systems. With more options for ...
Application of a 2.9 MGD Open-Platform UF/RO System for Selenium Removal From a Mine-Influenced Surface Water
This presentation is about a 2.9 MGD UF/RO project for the purpose of removing selenium from a mine-influenced surface water. It's important because of the limited published work regarding UF/RO application for selenium rejection, and the use of an open-platform UF system in an industrial application, which is one of if not the first documented ins...
Evaluation of an Integrated Tertiary Treatment System for Ultra-Low Level Phosphorus Removal in Hayden, Idaho
The Hayden Wastewater Treatment Plant process consists of a headworks, equalization, enhanced biological nutrient removal, oxidation ditches, and secondary clarifiers. The facility produces typical effluent total phosphorus (TP) concentrations in the range of <1.0 mg/L as P. However, during upset conditions, these effluent concentrations can often ...
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 WTP system into compliance and work with existing infrastructure options and limits, the City elected to install a two-stage ultrafiltration system in ...
