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, […]
Silt Density Index: A Fresh Perspective on an Old Index
This paper demonstrates the need for consistency in the use and selection of silt density index (SDI) filter pad chemistries by membrane treatment plant operators for their specific facility. While […]
What?s New in RO Membrane Cleaning? Micro-Bubbles and High Ionic Strength Effervescent Cleaners Enhance RO Membrane Foulant Removal
The use of micro bubbles, effervescents, and high ionic strength cleaneres are explored for novel approaches for the removal of foulants on RO and NF membrane surfaces. The unique part […]
Membrane Filtration at the Waimea Water Treatment Plant Will Provide More Than Just Clean Water
To address the issues of an aging WTP and licensure requirements, the Wiamea WTP began a project to upgrade its plant with membrane filtration to reliably produce 4 MGD. A […]
MF/UF Back to Basics Water Reuse & MBR?s
This presentation from a preconference workshop in 2014 for Back to Basics on membrane technology discusses water reuse and membrane bioreactors. A description of the various aspects of water reuse […]
Therma-SEP: A High Temperature Membrane Based Desalination Technique for Produced Water Treatment
This paper presents preliminary findings from the laboratory scale operation of Therma-SEP? using model saline waters and produced waters. A novel inorganic-organic composite membrane was used to evaluate the process.
Organic Pollution Remediation in Wastewater Reverse Osmosis Concentrate by Advanced Oxidation
This paper describes the work on advanced oxidation of phenolic pollutants in reverse osmosis concentrate.
Antimicrobial and Bacterial Anti-adhesive Properties of Polysulfone Membranes Modified with PAH/PAA Multilayers and Silver Nanoparticles
Polymeric microfiltration membranes used to treat wastewater are subject to file fouling due to the diversity of microorganisms present in wastewater. Surface modification of polymeric microfiltration membranes using polyeletrolyte multilayer […]
Lessons Learned from Start-up of the 10 MGD Membrane Bioreactor at Irvine Ranch Water District.
This large-scale membrane bioreactor (MBR) project by a progressive water agency in semi-arid Southern California provides a useful model for others to emulate. The project advances the use of the […]
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 […]
