Forward Osmosis Evaluation and Applications for Reclamation
Project ID: 7911
Principal Investigator: Miguel Arias-Paic
Research Topic: Desalination and Water Treatment
Funded Fiscal Years: 2015
Keywords: water treatment, forward osmosis, desalination, low energy
The following research questions will be answered in this work:
1. Is there technical merit to the concept of fertilizer driven forward osmosis?
2. Is there merit to residential scale, in-home FO systems for grey water treatment for remote communities, such as the Navajo Nation?
3. Is recovering an ammonium bicarbonate draw solution with ion exchange economical and technically feasible?
4. What configurations and applications of forward osmosis have the greatest potential to compete with other water treatment technologies for solving Reclamation's water supply challenges?
Need and Benefit
According the National Academy of Sciences 2008 report on Desalination, there is a need to "develop approaches to lower the financial costs of desalination so that it is an attractive option relative to other alternatives in locations where traditional sources of water are inadequate" and "develop novel approaches and/or processes to desalinate water in a way that reduces primary energy use." Because of advances in membrane properties and process operation, forward osmosis may have the potential to meet those needs.
There has been a lot of interest lately in forward osmosis in the water treatment industry. There have been companies selling FO systems (like Oaysis) and membrane manufacturers focusing on marketing FO specific membranes (HTI). The most recent NAMS annual conference featured 3 sessions on FO presentations. Because the field of FO is moving very quickly due to this increased interest in the technology, understanding where FO can serve Reclamation's needs in a cost effective, environmentally sound manner may help meet Reclamation's mission.
