The Water Research Foundation (WRF), which sponsors water research, has launched two new potable water reuse research projects focused on supporting potable reuse blending operations.
Potable reuse could potentially be implemented in a variety of different ways and one of the remaining research questions is where the best location is for this highly treated water to be blended with other supplies, WRF says. Water produced from a potable reuse facility could potentially be blended directly into the potable water distribution system, added upstream of a water treatment plant, or added directly within a treatment plant between various processes. More information is needed about the impact of blending to treatment operations and water quality issues in the distribution system.
With an estimated completion date of late 2016, this project will develop recommendations and guidance for the appropriate use of blending as part of a direct potable reuse project. The blending assessment will include evaluations of treatment, impact of different water qualities and blending locations, summary of corrosion issues, and the impact on engineered storage buffer design.
The second project, scheduled for completion in early 2017, will create a guidance framework of methods and techniques that water utilities and regulators can use to demonstrate the safety of potable reuse water. This project will help facilitate a proactive potable reuse monitoring process that is protective of public health.
Earlier this year General Electric Analytical Instruments’ parent company GE Water & Process Technologies launched an online platform to share industry insight and discuss interesting concepts surrounding the impact of water reuse on industrial and municipal sectors.
