The Water Research Foundation Issues RFPs On Ozone/BAF Treatment And Wastewater Treatment Performance In Potable Reuse Applications

The Water Research Foundation (WRF) has issued Requests for Proposals (RFPs) for two new projects funded with backing from WRF’s Advancing Potable Reuse Initiative. These projects will build on The Water Research Foundation’s existing potable reuse research portfolio, which has helped establish indirect and direct potable reuse as a solution to the nation’s water supply challenges and as a reliable and sustainable component of integrated water management.

The two projects now open for proposals are as follows:

Evaluation of CEC Removal by Ozone/BAF Treatment in Potable Reuse Applications (Reuse-17-04)
For some inland locations interested in implementing potable reuse, reverse osmosis is often not feasible due to cost or brine disposal considerations, and ozone/biologically active filtration (BAF) is often proposed as an alternative. Although considerable research is underway to understand the variables and operational conditions affecting total organic carbon (TOC) and CEC removal through ozone/BAF-based treatment, findings have not been compiled in an accessible or actionable format. This project will synthesize the results of the existing research to develop design and operational guidelines to facilitate the broad implementation of ozone/BAF in potable reuse applications.

Understanding Wastewater Treatment Performance on Advanced Water Treatment Processes and Finished Water Quality (Reuse-17-05)
As potable reuse becomes more commonplace, conventional wastewater treatment processes must be recognized as pretreatment for the downstream advanced water treatment (AWT) train. The operation of various wastewater processes will impact the type of treatment needed within the AWT train to produce water that is protective of public health and meets regulatory requirements. While the qualitative impacts of some wastewater processes on AWT train performance have been defined, a broad quantitative analysis has not been completed for the full range of potential primary, secondary, and tertiary treatment processes that can be used ahead of AWT trains. This research will help utilities optimize wastewater treatment processes to benefit the AWT train and improve finished water quality. The information could assist in the selection of AWT treatment processes, operations and maintenance practices, levels of conventional and advanced treatment needed, and overall system performance.

The full RFPs can be viewed online. Details on the proposal process and selection criteria are detailed in each RFP. Proposals are due by 8:00 pm ET on Friday, March 23, 2018.
