Pilot Testing for Validation of Log Removal Credit for Reverse Osmosis and Nanofiltration Membranes
Application of potable water reuse in the U.S. has become more widespread to meet the water demand in areas with increasing population and dwindling water sources. Different treatment trains have […]
Verifying MBR Membrane Integrity with Pressure Decay Testing; Implications and Interpretation of Test Pressure
The question of pathogen Log-Removal Value (LRV) credits for the MBR process still looms over next-generation wastewater reuse plants. Based on the Membrane Filtration Guidance Manual, the Pressure Decay Test […]

The Influence of Complex Ions in High Recovery and Brine Concentrator Saturation Calculations
As RO systems are pushed to increasingly higher recoveries, the concentration of salts in solution increases exponentially. This drastic increase in salt concentration demands more complex scaling calculations for proper […]
Advancements in Ceramic Membranes – They are Not All the Same
Ceramic membranes are commonly used for both water and diesel filtration. However, the first ceramic membrane was not originally designed for these applications. The first ceramic membrane was developed during […]
Hitting a Moving Target – Designing an MBR System with Uncertain Nutrient Limmits
The Fort Mill Water Pollution Control Plant (WPCP) is currently permitted to treat a capacity of 3.0 mgd, with current flows closer to 1.3 mgd. Due to the proximity of […]
Using MBR for On Site Water Recovery in New Mexico – Challenges and Solutions
The Albuquerque Bernalillo County Water Utility Authority (Water Authority) is developing a state of the art on site water resources recovery plant, located at a shopping center in the uptown […]
Brine Minimization Maximizes Potential for an Inland Potable Reuse Project
Rancho California Water District (Rancho Water/District) in Temecula, California has been investigating options for a groundwater injection indirect potable reuse (IPR) project to provide a locally controlled, drought-resistant supply that […]
The Evolution of High Recovery Reverse Osmosis to Achieve 95%+ Recovery
Increasing regulatory requirements and disposal costs around the world, as well as ESG mandates and incentives for recycling, are prompting industries to reduce their water and energy footprint, and highlight […]
