Here’s the release from the Bureau of Reclamation (Marlon Duke):
Goals are to reduce costs, energy requirements, environmental impact for treating unusable water
The Bureau of Reclamation has awarded nearly $1 million for projects under an innovative pilot-scale water treatment technologies and desalination program. The selected projects will receive funding through cooperative agreements and will include a period of pilot testing at the Brackish Groundwater National Desalination Research Facility in Alamogordo, New Mexico, and other sites across the country.
On April 30, 2019, Reclamation announced that it was seeking applicants looking for innovative technologies for reducing the cost, energy requirements and environmental impacts for water purification and desalination technologies. Innovative and promising technologies would be supported to move from the theoretical stage towards a practical application.
“In June, we received 29 eligible applications for review that included $4 million in requests for federal funding. Top applicants were invited to pitch their pilot studies in August,” said Yuliana Porras-Mendoza, advanced water treatment research coordinator. “We awarded grants to seven projects focused on innovative and disruptive water treatment technologies ready for pilot testing to accelerate knowledge transfer and provide new products that serve the water treatment community and attract commercial interest.”
Funded Pilot Studies
Garver, LLC: Innovative electro-coagulation membrane pretreatment with vacuum-assisted electro-distillation concentrate management for cooling tower blowdown recovery
Project goal: improve water quality, reduce chemical consumption, reduce the potable water demand of a water treatment system and eliminate dissolved solids loading to the local sewershed.
AdEdge Water Technologies: Innovative high recovery flow-reversal RO desalination process for potable reuse providing essential physical barrier with higher recovery rate & reduction in concentrate flow
Project goal: test a flow-reversal reverse osmosis technology with the purpose to introduce this technology to the US market.
WIST, Inc: The first affordable, easy-to-use silica pretreatment solution: Pilot scale validation of SiSorb-Nano
Project goal: scale up and test a new resin for silica removal from water that is less expensive, more efficient, and environmentally friendly.
State: New York
Eastern Shore Microbes: H.E.A.T A biologically, sustainable solar powered system to eliminate RO concentrate in order to improve the water supply for inland communities
Project goal: test the ability for a selected group of microbes to enhance evaporation of reverse osmosis concentrate, potentially reducing the size of current evaporation ponds and increasing the rate of evaporation.
University of Arizona: Electrochemically enhanced high efficiency reverse osmosis (EE-HERO) for brackish water treatment
Project goal: test an electrochemically enhanced high efficiency reverse osmosis process for treating brackish groundwater for potable use.
University of Utah: Disruptive transport/sand filtration pretreatment system for uninterrupted desalination water supply during harmful algal blooms
Project goal: test an innovative system as a last defense during a harmful algal bloom (HAB) before it reaches water treatment systems that are severely impacted and, in some cases, not able to operate during a HAB event.
EcoVAP: Enhanced evaporation using biomimicry for brine concentrate disposal
Project goal: minimize the cost and environmental impact of inland desalination.
The funding provided supports the Presidential Memorandum on Promoting the Reliable Supply and Delivery of Water in the West, including the goal of improving use of technology to increase water reliability and enabling broader scale deployment of desalination and recycled water technologies.
