The Round Mountain WTP: A Brackish Water RO Facility for Water Self-Reliance and Regional Salinity Management
This paper and presentation address the permitting issues and cost evaluation for an inland brackish water treatment plant. The solution to these challenges created a successful model for the region […]
Economics of Brackish Water Resources
In Arizona, fresh water sources are currently and will continue to be limited. Natural surface waters are already fully developed, many groundwater sources are being over drafted, and the State’s […]
Integration of RO and PRO to Decrease Energy Expenditures in Seawater Desalination
While wind and solar are among the most well known renewable resources, salinity gradient power in nearly untapped and has the potential to increase renewable energy production by 20%. Pressure […]
Teaching Old Dog New Tricks: Electrodialysis Reversal Improvements and Innovations
Electrodialysis Reversal began in the 1970s as an improvement on the Electrodialysis technology with a cell pair composed of an anion membrane, a diluting spacer, a cation membrane, and a […]
Backwash Free Ultrafiltration for Silicon Wafer Production Wastewater Recycling
The semiconductor industry uses 1,500 gallons of ultrapure water to make a single 300 mm silicon wafer which generates a high volume wastewater stream high in silicon and turbidity. Using […]
