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 […]
Coupled Oxidant-Membrane Processes for Decreased Fouling and Enhanced Flux in Water Reclamation Application
Water reuse has become an important research topic for water resource and water treatment professionals in recent decades. Water reuse is quickly being accepted as one strategy that can be […]
Repair and Rehabilitation of Twenty-Year-Old NF Plant Trial and Tribulation
The Deep Aquifer Treatment System (DATS) is an 8-mgd nanofiltration (NF) plant owned and operated by the Irvine Ranch Water District (IRWD) located in Santa Ana, California, that was put […]
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 […]
Maximizing Flexibility with MBR to Reduce the Long-Term Cost to Operate
The largest costs in water and wastewater projects are generally the long-term cost to operate, or cost of service (COS), over the initial capital investment for the planning, design, construction, […]
Practical Applications of Low- and High-Pressure Membranes for PFAS Removal
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 […]
