Establishing a Baseline of Virus Removal by a Full-Scale Reverse Osmosis Sytem
Recent activity in the potable reuse field incorporates reverse osmosis (RO) processes as a requirement to provide pathogen removal and a reduction of other compounds. California has implemented the 12-10-10 […]
NF/RO Membranes Ability to Remove 1,4-Dioxane From Water Sources Used for Drinking Water Production
As research advances, compounds contained in water resources are being identified and regulated for removal during treatment chain for drinking water production. This is closely linked to the evolution of […]
Regional Experience with Small Membrane Plants Leads to Improved Design and Operations
Maryland Environmental Service (MES) operates over 200 water and wastewater facilities throughout the State of Maryland. Among these are 11 membrane plants at facilities ranging from 5,000 to 900,000 GPD […]
Established Practices, Innovative Design, and New Products: A New Generation of Ultra High Pressure Desalination
In common parlance, reverse osmosis (RO) is often described as removing salt from water. In practice however, these processes squeeze water from a salt solution resulting in concentrate to be […]
Membrane Performance Following Five Years of Continuous Use of Non-Chemical Dechlorination
Facing frequent membrane and micron-filter maintenance and replacement as a result of biological fouling and oxidation despite their use of a SMBS dechlorination process, Plant Bowen, a 3,160 megawatt coal-fired […]
Impact of Shock Organic Loading Rates on Fouling and Clogging Frequency of Membrane Bioreactors
Contrary to the traditional view, membrane technologies have offered solutions for reusing water obtained from sources such as seawater and wastewater. A limitation caused by membrane technologies, however, has been […]
The Four Essential Factors for a Successful CIP
Alternative Membrane Module Evaluation for the City of Thornton Submerged Membrane Plant
The City of Thornton (City), Colorado operates a 50 mgd water treatment plant (WTP) with a submerged ultrafiltration system. The Wes Brown Water Treatment Plant was originally constructed as a […]
The Effectiveness of Ceramic Ultrafiltration as a Pre-Treatment for SWRO at TUAS Spring Singapore
SWRO pre-treatment with polymeric MF/UF membranes initially gained a wider acceptance mainly due to its reported superior removal of particulate and colloidal foulants (absolute filtration), low footprint and its benefits […]
Managing Membrane Health and Performance – A Case Study
Operating a membrane plant can be challenging insomuch as there are limited direct observations that can made to asses condition. In this respect, it is much like piloting a submarine; […]
