Membrane Pretreatment with Ion Exchange for Natural Organic Matter (NOM) Removal

Project ID: 536
Principal Investigator: Steve Dundorf
Research Topic: Desalination and Water Treatment
Priority Area Assignments: 2011 (Advanced Water Treatment), 2012 (Advanced Water Treatment)
Funded Fiscal Years: 2010, 2011 and 2012
Keywords: None

Research Question

* What portion of NOM is responsible for membrane fouling in pretreatment and desalination systems?

* Provided with this answer, what are potential methods to remove this NOM or NOM fraction?

Need and Benefit

Since removal of all NOM can be difficult and expensive, removing a certain fraction of NOM may be more desirable and less expensive. Therefore, Bureau of Reclamation (Reclamation) research in this topic represents a potential cost savings for all Reclamation clients using a membrane filtration process for water treatment. Reclamation water treatment design engineers are almost always faced with some amount of NOM removal required when designing water treatment plants.
