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 al, 2014). The MABR process employs a gas permeable media to deliver oxygen to a biofilm that is attached to the surface of the media. […]

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, and commissioning of new facilities. Therefore, decisions made during the delivery of the project have the greatest potential for influencing the ability to reduce the […]

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 the service area to the City of Charlotte and ongoing local development, annual average flows are projected to almost triple by the year 2024. As […]
Lessons Learned in the Construction of an 18.3 MGD Sulphate Removal Process (SRP) System for Oil Field Production
In early 2017, SafBon Water Technology (System Supplier), working directly with a global engineering consulting firm, was awarded one of the largest Sulphate Removal Process (SRP) projects to supply an 18.3 MGD (69,300 m3/d) Nanofiltration (NF) system located in the Kingdom of Saudi Arabia (KSA). The heart of the project is the 2-stage Nanofiltration (NF) […]
The Value and Challenges of Chlorination/Dechlorination Process Optimization in Power Generation
Quality of the steam cycle water requires special attention and chlorination/dechlorination phase is very important, especially for reclaimed water sources. Efficient control of residual chlorine allows for minimizing RO membranes maintenance and extending their life. Optimized dechlorination, permitted by accurate ultra-low range chlorine monitoring, resulted in over 30% reduction in sodium bisulfite usage and halved […]
Longer Term Impact of Desalinated Water on Blended Supplies
The Claude “Bud” Lewis Carlsbad Desalination Plant (CDP) was completed in December 2015 and produces approximately 50 MGD of locally controlled drought-proof, potable water for San Diego County. The Water Research Foundation (WRF) initiated Project 4773, entitled Carlsbad Desalinated Seawater Integration Study, to assess the integration of seawater desalinated with reverse osmosis (SWRO) into the […]
Longer Term Impact of Desalinated Water on Blended Supplies
Lifecycle Cost Analysis of Photobioreactor Followed by Secondary RO for Enhanced Water Recovery in Brackish Water Desalination
Population growth and prolonged and frequent drought events call for an urgent need for alternative sources of water. The use of unconventional water resources such as brackish water and reclaimed water has become a viable option because of the recent advances in reverse osmosis (RO) technologies. As of March 2021, there are more than 1,200 […]
