Improving MF/UF Membrane Operations and Troubleshooting with 4 Easy Steps
The paper presents suggestions for improving operations of MF/UF membrane-based treatment plants based on the author?s 35 years of experience with the goals of making the operator?s work life easier, […]
Can Fine Automatic Screen Filters Replace Disposable Cartridges? Pilot Pre-Treatment Results from a Seawater Desalination Plant
A unique screen flushing mechanism enables a reliable continuous operation of a very fine screen (
Membrane Concentrate as a Resource
The Mineral Recovery & Enhanced Desalination (MRED) Process
Use of brackish ground water for inland communities is challenging because, unlike sea water which is soft and amenable to desalination, desalination of brackish ground water is limited by mineral […]
Direct Contact and Vacuum Membrane Distillation Processes for Water Recovery
In this study, two MD configurations, vacuum membrane distillation (VMD) and direct contact membrane distillation (DCMD), were compared under different operating conditions. It was found that under the same conditions […]
Conventional ZLD: Overview and Economics
The use of alternative, lower quality sources, such as brackish groundwater, saline surface water, and recycled wastewater (i.e., for potable reuse) are rapidly becoming an integral component of long-term portfolio […]
Hybrid Algal-Osmosis Membrane System for Resource Recovery and ZLD Applied to Municipal Wastewater
An algal wastewater treatment process was combined with a hybrid forward osmosis (FO) and reverse osmosis (RO) membrane system to treat urban wastewater, harvest algae for recovering energy and nutrients, […]
Brine Concentration-Evaporation
I will discuss the different types of evaporators and the applications/restrictions of each type. I will go into heating methods including Mechanical Vapor Compression (MVR), Direct Steam, Thermal Vapor Recompression […]
Closed Circuit Reverse Osmosis (CCRO)
The mass adoption of a newly emerging Closed Circuit Reverse Osmosis (CCRO) technology across multiple industries represents one of the most fundamental breakthroughs in reverse osmosis since its commercialization in […]
Concentrate Enhanced Recovery Reverse Osmosis (CERRO)
Researchers at UTEP partnered with El Paso Water (EPW) to develop the high-recovery concentrate enhanced-recovery reverse osmosis (CERRO) process. Implementation of full-scale CERRO units at well sites in El Paso […]
