The Bureau of Reclamation is providing $1.69 million to nine projects that offer innovative and novel water treatment technologies that may make previously unusable water available. The funding is being provided for the recipients to conduct pilot testing on their proposed technology, according to a news release from Reclamation.

“Reclamation has been supporting utilizing new and novel technologies for water resource development for 120 years,” said Chief Engineer David Raff. “Water treatment technology is evolving rapidly, and these projects can improve and expand the accessibility to previously unusable water, especially for communities with some of the most urgent water needs.”

The selected projects are:

• Carollo Engineers, Inc.: Pilot Testing of a Novel Energy Efficient Configuration for Carbon Diversion and CEC Removal, $200,000
• Carollo Engineers, Inc.: An Innovative Ion Exchange-Based Advanced Treatment (XBAT) Approach for Direct and Indirect Potable Reuse, $199,989
• Enspired Solutions LLC: Reductive Defluorination PFAS Destruction Field-scale Pilot Test, $200,000
• Hazen and Sawyer: Improving RO Recovery through Optimization of Flux and Pump Usage with Real-Time Sensor Connectivity, Data-driven Modeling, and Automation, $197,294
• Hazen and Sawyer: Pilot Scale PFAS Destruction in Membrane Concentrate via Electrochemical Oxidation, $196,916
• Orange County Water District: In-Situ Gravity Driven Removal of PFAS During Groundwater Recharge to Protect Drinking Water, $199,430
• South Platte Renew: Retrofitting Existing Infrastructure for Sidestream Biological Phosphorus Treatment to Reduce Coagulant Costs and Discharged Salts Associated with Chemical Phosphorus Removal, $100,000
• Southern Nevada Water Authority: Assessment of Innovative Dissolved Air Flotation Approaches for Conventional Water Treatment, $200,000
• The Research Foundation for The State University of New York – Stony Brook University: Enhancing the Removal of Hydrophilic Per- and Polyfluoroalkyl Substances (PFASs) by Granular Activated Carbon using Hydrophobic Ion-pairing as Pre-treatment, $199,601
