A Novel Calcium Carbonate Scaling Model for Calculating Maximum Recovery and Inhibitor Dosages in Industrial RO Applications
The purpose of this work was to identify a method for determining maximum recoveries in RO systems where calcium carbonate was a concern, and to find a reliable method for […]
Drinking Water Permit for the Carlsbad Desalination Facility -Demonstrating How To Obtain Log Removal Credits for RO Membranes
RO Membrane Surface Factors Influencing Specific Flux
Reverse osmosis (RO) membranes used to treat municipal wastewater for reuse become fouled with inorganic, organic and biological materials present in the feedwater, causing a decrease in RO efficiency. The […]
Direct Membrane Treatment Of Anaerobic High Iron And Manganese Groundwaters
Historically there has been an industry-wide perception that if a feedwater source contains dissolved metals they must be removed via oxidation and filtration prior to RO membrane treatment. The purpose […]
Custom Engineered Microfiltration – West Basin’s Upgrade at The Carson Regional Water Recycling Facility
This presentation provides an overview of the design of a custom engineered microfiltration for West Basin Municipal Water District. The system is designed to accept 6 different membrane modules. The […]
The Economics of Seawater Reverse Osmosis Desalination Projects
Desalination applications based on reverse osmosis (RO) technology today comprise over 50% of the capacity of all desalination systems worldwide and represent 75-85% of new desalination projects being implemented. The […]
Comparison of Polymeric and Ceramic MF/UF Membrane for the Treatment of Produced Water
This presentation briefly summarizes the design and operation of a microfiltration for treating a pretreated produced water.
Bio-methane production variation under different draw solute reverse diffusions in an anaerobic digester simulated for FO-AnMBR
This study was conducted to investigate the relationship among the reverse diffusion of fertilizer draw solute, bacteria community and bio-methane production rate in the FDFO-AnMBR system. Three fertilizers were evaluated […]
Achieving Stringent Nutrient Compliance
With environmental regulators placing ever greater scrutiny upon nutrient control, many wastewater treatment facilities, both new and existing, are having to review additional processes and technologies to achieve effluent compliance. […]
Performance Metrics for Ageing of Drinking Water Membranes
Our work explores how drinking water membranes age over the long-term in operational settings. By partnering with water treatment plants and monitoring their membranes over several years, the performance of […]
