Membrane Filtration for Arsenic Removal from Groundwater in Industrial Applications
This abstract will discuss background information to provide context for arsenic removal from a regulatory and health perspective, as well as a brief overview of alternate treatment methods. This paper […]
Is Organic Fouling Making Your Life Difficult? Mitigation of Organic Fouling of Low Pressure Membranes Using LC-OCD
This paper will describe the use of a unique organics characterization method, liquid chromatography with on-line carbon detection to identify the primary cause of organic fouling in two fouling scale […]
Custom Engineered Membrane Filtration Pilot on Ozonated Secondary Effluent Water as a Source
The water reuse industry has transitioned from proprietary microfiltration (MF) systems to MF systems designed by original equipment manufacturers (OEM) that can be adapted to operate a handful of membrane […]
Potable Reuse Side-by-Side Pilot Testing – O3-BAF vs. UF-RO on Two Different Source Waters
JEA recently completed Phase I of a 3-Phase plan to test and implement a potable reuse project. Phase I was a pilot-scale evaluation of alternative treatment trains (O3-BAF vs. UF/RO) […]
Concentration Polarization Modeling for Reverse Osmosis Membranes with Engineered Surface Features
Fouling has always been an issue in all membrane systems, and it is more problematic when concentration polarization (CP) is high.This research investigates how patterns can affect CP layer in […]
Boil water advisory, algae and organics: Membrane Technology for rescue
This presentation describes the upgrade pathway of a small indigenous community water treatment facility that was not meeting the water quality standards. This includes process selection, side-by-side pilot testing to […]
A 10-Year Journey to a New Desalter, Now What?
In-Line Coagulation Upstream Ultrafiltration – Comparison of Continuous vs. Intermittent Addition
The subject of this summary is the comparison between continuous and intermittent coagulant addition upstream of ultrafiltration membranes to remove organic compounds and thereby minimize the biological fouling of reverse […]
Removal of Colloidal Particles through Online Monitoring to Lower Microfiltration Membrane Fouling
Fouling of microfiltration (MF) membranes results in increased energy demand, increased cleaning intervals, and membrane replacement frequency. MF membrane fouling is largely due to deposition of colloidal nanoparticles
A Simple and Reliable Lab Tool to Anticipate Risks of UF Membrane Abrasion at Full-Scale
A new method for direct measurement of the abrasion propensity of UF membranes used in water treatment plants was developed. Standard conditions were determined to obtain a rapid response.
