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) […]
First Year Operating the City of Gearhart Oregon Arsenic Removal Membrane Water Treatment Plant
This paper presents the operating and performance results for the first 13 months of operation at the City of Gearhart?s water treatment plant. Membrane hydraulic performance is discussed with respect […]
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, […]
Removal of Inorganic Scale from RO Membranes using Dissolved CO2
Membrane fouling is a major operational issue in reverse osmosis (RO) desalination plants. In particular, plants treating brackish groundwater can encounter troublesome inorganic membrane scales. A novel cleaning method is […]
The Mesa Water Reliability Facility – Achieving a Local, Sustainable Water Supply in Southern California
This paper describes the Mesa Water Reliability Facility?s treatment system, which includes nanofiltration (NF). Operational challenges included: inconsistent results between silt density index (SDI) filter pad technologies; membrane fouling characteristics […]
The UFO-MBR – a Potable, Indirect Potable, and Nutrient Recovery Technology
The implementation of potable reuse will require treatment processes with multiple barriers to prevent microbial, nutrients, and other contaminants of concern from compromising public health. The osmotic membrane bioreactor (OMBR) […]
MF/UF Water Quality, Performance, and Applications
This presentation from a preconference workshop in 2014 for Back to Basics on membrane technology discusses microfiltration and ultrafiltration water quality and how it influences system performance. System design and […]
When Your Source Water Changes The Game Changes Knowing how to switch gears when Operating a Micro Filtration System
This presentation reviewing the transition to as microfiltration plant at the Water Replenishment District in California was given at a Preconference Workshop in 2014 that discussed membrane plants from an […]
Has Your Membrane System Had A Tune Up Lately?
The first part of the presentation will discuss how to review membrane system performance by looking at historical trends, checking operating sequences to determine effectiveness and perform a close review […]
The Simplest Possible RO Pretreatment for Scale and Colloidal Fouling Control
In this paper, the simplest possible pretreatments needed for controlling of reverse osmosis (RO) membranes arising from dissolved salts and invisible colloidal particles will be addressed. The new generation of […]
