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 […]
Selection of Analytical Methods and Sampling Techniques for Membrane Treatment of PFAS in Water
High-Pressure Reverse Osmosis System Treating Wastewater from a Pharmaceutical Production Facility as Part of a ZLD Projectg
As part of compliance requirements, a new pharmaceutical assay production facility in Shanghai, China, owned and operated by a major multinational pharmaceutical company, was required to implement a zero liquid […]
Optimizing Organics Removal from Surface Water in a Coagulation / Ultrafiltration System
Surface waters contain inorganic and organic particulate substances that need to be addressed and potentially reduced for drinking water production. Inorganic particulate constituents are amongst others clay, silt and minerals. […]
No-Break Fiber Solves Membrane Integrity Problems at Five Water Treatment Plants
Fiber breakage continues to be a problem for low-pressure membrane systems in drinking water plants. Not only do membrane integrity issues increase the risk of pathogens in the potable water […]
