DENVER - October 20, 2016 (www.waternewswire.com) The Water Research Foundation (WRF), a leading sponsor of potable reuse research, has released interim results from the project "Blending Requirements for Water from Direct Potable Reuse Treatment Facilities" (#4536). The objective of this project is to provide guidance for the appropriate use of blending as part of a direct potable reuse (DPR) project. The study is examining the impact of four blending variables: source water type, blending location, recycled water ratio, and type of advanced treatment train. The video, Exploring Potable Reuse to Diversify Water Supplies, provides a preview of the project.
Four utilities are participating in the bench-scale treatment/distribution system study: Santa Clara Valley Water District (SCVWD), City of Ventura, Clark County Water Reclamation District, and Los Angeles Department of Water & Power. The bench-scale simulations were based on the participating utilities’ full-scale processes. The parameters tested include pathogens, emerging contaminants, regulated contaminants, corrosion-related issues, and general parameters such as pH and turbidity. Preliminary findings are as follows:
Bench testing using water from SCVWD, Ventura, and Clark County Water Reclamation District is complete and the data is being analyzed. Bench testing using water from LADWP is in progress. The research team will be issuing a survey to roughly 20 participating utilities to understand their perspective on blending, and gather some water quality data. The final project results should be published in early 2018.
WRF has been conducting innovative research on potable and non-potable reuse for over 40 years. Additionally, WRF has over a dozen ongoing projects on reuse, including:
"Freshwater supplies are dwindling in many regions within the U.S. and around the world due to climate change, competing demands, and expanding and shifting populations," said Rob Renner, CEO of the Water Research Foundation. "With dozens of completed and ongoing projects, the Water Research Foundation will continue to be a leader in ensuring that these regions can adopt potable reuse as a practical option to provide safe drinking water to their communities."
