PureWater Colorado demonstration project uses Xylem technology

Xylem Inc is providing water technology solutions to the PureWater Colorado Demonstration Project, which aims to demonstrate direct potable reuse (DPR) as a safe, reliable and sustainable drinking water source.

A range of Xylem’s solutions including a Wedeco MiPRO advanced oxidation process (AOP) pilot system and a Leopold granulated activated carbon (GAC) filter pilot will be used in the project which features a unique treatment train that avoids the use of reverse-osmosis (RO) membranes.

Denver Water has partnered with Carollo Engineers, WateReuse Colorado (WRCO) and Xylem on the project which is located at the Denver Water Recycling Plant and will run during April this year. Some of the water produced will be used to brew beer to raise awareness among the general public about this water purification process.

Water reuse is part of Colorado’s Water Plan to reduce the amount of water diverted from rivers and streams, creating a sustainable, efficient way to extend the state’s water supplies.

“We are very excited to be part of this forward-looking, important project that aims to promote a sustainable, reliable and safe drinking water treatment process,” said Steve Green, business development manager, Xylem. “It is crucial that we implement sustainable solutions, like water reuse, to meet future water needs. We hope that this demonstration will help to raise awareness and understanding among the local population and community leaders about how DPR can help to provide for their water needs now and in the future.”

Last year Xylem signed a multi-year commitment (2017–2019) to support Water Environment Research Foundation (WE&RF) research into water reuse, building on a previous three-year research partnership. Internationally, Xylem works together with the IVL Swedish Environmental Research Institute and the Singapore Public Utilities Board (PUB) to progress water reuse.
