Under this Cooperative Agreement, the Cal Poly Pomona Foundation will assistin development of Closed-Circuit Reverse Osmosis (CCRO).

The intent of theproposed project is to further development needed by Reclamation andstakeholders, municipalities and academics, with a Reverse Osmosis processthat

can remove most Contaminants of Emerging Concerns (CEC) yet produceconcentrate streams with increased CEC concentrations that require furtherunderstanding.

The discharge of CEC rich concentrate stream can increase plantoperational costs and thus provide a roadblock for the implementation waterreuse.

The research areas of focus:Understanding the fate and removal of CECs in any water reclamationpilot study would respond to the lack of knowledge around CECs inwater reclamationReducing the discharge volume of concentrate stream is important sinceit directly affects the cost of water reclamation process specially ininland water reclamation plantsResearchers at Cal Poly Pomona Foundation will focus on the following tasks:Literature studies will be performed to investigate and compile theavailable data on CECs in CCRO, and similar high recovery membranesetupsDevelopment of an experimental procedure in regard to samplecollection, and laboratory analysis of CCRO’s feed, product, and concentrate samplesStudying the fate and removal of CECs under different operatingconditions by commissioning, operation, and monitoring of the pilotCCRO, as well as sampling and sample analysis practices for watersamples for CEC studyData collection and analysis for developing a comprehensive data logthat includes operating conditions and water quality
