The Economics of Energy Recovery Devices
Energy recovery is now common in all seawater membrane treatment processes and selecting the appropriate energy recovery technique and device must include and examination of the capital cost (CAPEX) as […]
Ceramic Membrane Filtration of Wastewater Effluent and High-NOM Surface Water: Fouling Management
This work focused on viable pre-treatments options available for managing fouling of ceramic membranes caused by impaired water sources, emphasizing wastewater effluent and high-NOM surface water. Hence, hybrid processes composed […]
Evaluation of Treatment Performance and Membrane Fouling Propensity of Different Pore-Sized Ceram
Anaerobic membrane bioreactors offer a wastewater treatment process that uses less energy and space than an aerobic MBR. The anaerobic process leads to more frequent fouling and therefore more frequent […]
Ceramic Membrane Filtration of a Surface Water Treated with Ion Exchange
Pilot-scale trials of four different pre-treatments to ceramic membranes were performed for a surface water in southwest England. A study of the organic character of the feed and treated provided […]
Electrodialysis Metathesis: A New Brine Minimization Technology
This presentation discusses the practical application of electrodialysis metathesis (EDM), as experienced while operating two pilots in Colorado, including information on how the EDM system differs from traditional electrodialysis (ED) […]
Chemical Treatment of MF/UF Residuals to Achieve Near Zero Liquid Discharge
Recovery of wastewater from the low pH clean in place of a UF/MF membrane plant can increase plant operating cost. By adding phosphoric acid and calcium to the wastewater calcium […]
Maximizing Water Resources: A 99% Efficient Membrane Treatment System
This paper and presentation provide an overview of the following: history of project and why 99% efficient is cost effective; configuration of the new treatment system; discussions with regulatory agencies […]
Microfiltration and Ultrafiltration Standardization – A Review of Current Mechanical and Process Convergence and a Look Forward.
Without a standard approach to process and mechanical convergence of MF and UF treatment systems, end users and consulting engineers continue to deal with one-of-a-kind, non-interchangeable and incompatible systems. This […]
Facilitation of Advances in UF Membrane Validation through a Third Party Consensus Standard
The EPA sponsored regulations for testing the integrity of UF/MF membranes expired in 2013 and have been replaced with NSF/ANSI Standard 419. The standard provides more specific testing requirements and […]
Metrics & Methods for MF/UF System Optimization
This paper covers a wide variety of the current knowledge base about how to best operate and maintain a membrane filtration facility. Its authors cover the range of professionals with […]
