Oxford MBR Membrane Longevity: How Many More Years?
A portion of the London Ontario Oxford Pollution control plant was retrofited from conventional activated sludge to a membrane bioreactor (MBR) plant. Key operating and design factors for membrane life are variations in feed flows and fluxes. Mixed Liquor Suspended Solids (MLSS) have practical limits to maintain membrane life....
Implementing an Integrated Membrane System For CRWC - Headingley WTP
Cartier Regional Water Headingly WTP in Canada makes potable water from a river surface water source using ultrafiltration (UF) and reverse osmosis (RO). This is an Integrated Membrane System (IMS). Removal of Natural Organic Matter (NOM) is important for taste and oder control....
Exceeding 90% Recovery with Conventional and Closed-Circuit RO: Results from Parallel Pilot Systems
For inland reverse osmosis (RO) systems, brine disposal is often difficult and costly, and there is significant interest in increasing recovery and reducing brine volumes. The City of Buckeye, AZ owns brackish wells that have trace amounts of arsenic, nitrate, and various metals, and is considering RO treatment for these wells. Stantec performed a ...

Optimization of Ceramic Ultrafiltration Membranes for Stormwater Treatment and Trace Megal Removal
Stormwater in urban watersheds is often contaminated with suspended solids, oil and grease, and various metals, and ceramic membranes may offer a robust option for treating all of these. In this study, an active stormwater treatment process consisting of ceramic ultrafiltration (CUF) with a solids contact loop followed by oxidative filtration was d...
