Research project proposals requested by WRRF

Two requests for proposals (RFPs) for research projects were issued by the WateReuse Research Foundation on 8 September 2011 under the Foundation’s Solicited Research Program and Feasibility Studies Program. Research contractors will be selected through a competitive process.

The RFPs, both due by 26 October 2011, are for:

Monitoring for Reliability and Process Control of Potable Reuse Applications

The need for new water sources has led some water agencies and other groups to consider implementing direct potable reuse (DPR). In DPR, purified recycled water is introduced directly into the potable water supply distribution system or into the raw water supply immediately upstream of a water treatment plant.

The objective of this project is to identify, evaluate, test, and validate systems that can be used to assure the public safety of potable reuse. The project is specifically focused on monitoring for the removal of regulated and unregulated compounds of concern, such as micropollutants and endocrine disrupting compounds.

Equivalency of Advanced Treatment Trains for Potable Reuse
The goal of this project is to determine whether and when potable water is better achieved through active management and control in a direct potable reuse system rather than through the less active controls of an unplanned indirect potable reuse system. This project is also intended to facilitate robust analysis of the treatment steps sufficient for safe direct potable reuse.

This project will clearly identify the benefits and tradeoffs of various treatment process trains for potable reuse. The goals of this project are to:

  • Consider and examine criteria needed to evaluate the adequacy of treatment for direct and indirect potable reuse
  • Develop a model that can allow for comparisons of alternate treatment trains for potable reuse
  • Test at least one advanced treatment train for direct potable reuse at a scale large enough to give information on real operating conditions.
