Hazen’s Troy Walker and Jason Curl co-moderated a debate titled “Reverse Osmosis Based Vs Carbon Based Treatment for Potable Reuse” on September 14th at the WateReuse Virtual Symposium. A full recording of the debate is now available.

Potable reuse has taken hold in several different parts of the United States. Broadly, the treatment trains can be divided into two camps:

  • Reverse Osmosis (RO) based treatment that uses RO as both a desalination step and removal barrier for contaminants – typically on a treatment backbone of membrane filtration/reverse osmosis/UV
  • Advanced Oxidation.A carbon-based system that uses carbon adsorption technologies with ozone-BAC/GAC/UV Advanced oxidation

This “debate” focused on operations, featuring operationally focused experts including Mehul Patel from Orange County Water District in California, Ryan Popko from JEA in Florida, Germano Salazar-Benites from Hampton Roads Sanitation District in Virginia and Kevin Linder from Aurora Water in Colorado.
