Evaluating Contaminates of Emerging Concern’s Fate in Potable Reuse Membrane Treatment

archived

Under this Cooperative Agreement, the Cal Poly Pomona Foundation will assist in development of Closed-Circuit Reverse Osmosis (CCRO). The intent of the proposed project is to further development needed by Reclamation and stakeholders, municipalities and academics, with a Reverse Osmosis process that can remove most Contaminants of Emerging Concerns (CEC) yet produce concentrate streams with increased CEC concentrations that require further understanding. The discharge of CEC rich concentrate stream can increase plant operational costs and thus provide a roadblock for the implementation water reuse. The research areas of focus: Understanding the fate and removal of CECs in any water reclamation pilot study would respond to the lack of knowledge around CECs in water reclamation Reducing the discharge volume of concentrate stream is important since it directly affects the cost of water reclamation process specially in inland water reclamation plants Researchers at Cal Poly Pomona Foundation will focus on the following tasks: Literature studies will be performed to investigate and compile the available data on CECs in CCRO, and similar high recovery membrane setups Development of an experimental procedure in regard to sample collection, and laboratory analysis of CCRO’s feed, product, and concentrate samples Studying 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 study Data collection and analysis for developing a comprehensive data logthat includes operating conditions and water quality
