Innovative Use of Engine Exhaust to Treat Reverse Osmosis Concentrate
The mission of the Cumberland County Improvement Authority (“The Authority”) is to develop projects which are integral to the economic and environmental sustainability of Cumberland County. To further this goal, […]
An Emerging Application for Low-Pressure Membranes: Treatment of Backwash Waste at Surface Water Treatment Plants for Potable Reuse
In this study, guidance is provided for applying microfiltration (MF) and ultrafiltration (UF) membranes to treat full-scale granular media filter (GMF) backwash water at drinking water plants. An example from […]
Tap into MBR – The Hamby Water Reclamation Facility Indirect Potable Reuse Project
How Improving Performance and Packing Density Can be Achieved Concurrently with a Flat-Sheet MBR
While its well-known Reverse Osmosis membranes were developed in the early 1960s and commercialized in the 1970s, it may be surprising to learn the first MBR system was also introduced […]
Real-Time Data Collection, Analytics, and Visualization for Operating and Maintenance of RO Membranes at Chino II, CA
Effective operation of RO systems is a data-intensive, multivariate, statistical, and preventative maintenance problem. Operators must monitor system’s key performance indicators (KPIs) such as pressures, conductivities, flow rates, permeate and […]
A Tale of Two Pilots: PFAS Removal with Thin Film Nanocomposite Membranes
Per- and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that have been manufactured and used in a variety of industries around the world since the 1940s. PFAS can […]
Statistical Analysis of Foulant Composition from Membranes Collected from Reuse Applications
The wide variety of water reuse applications has led to an equally wide array of fouling issues which require increasingly tailored solutions. These issues can be detrimental to membrane lifespans […]
Benefits of Operating with the New Thin-Membrane Technology in a Municipal Drinking Water RO
Mount Pleasant Waterworks (MPW) is currently operating the first municipal drinking water RO system using a new, thin membrane technology. The new technology increases the amount of active membrane area […]
Don’t Let Chemical Cleaning Dictate Membrane Life
Membrane life is one of the biggest drivers in life cycle costs for any membrane-based water or wastewater treatment plant. The math is very simple: short membrane life drives costs […]
Uniquely Innovative and Practical: Membrane Aerated Biofilm Reactor (MABR) for Nutrient Removal, Resiliency and Energy Efficiency
Membrane Aerated Biofilm Reactor (MABR) technology is an attached-growth process in which autotrophic and heterotrophic biofilm growth occurs onto a dense gas-permeable membrane delivering oxygen by molecular diffusion (Adams et […]
