PFAS Treatment Options and Considerations for Drinking Water Utilities

Original Broadcast: October 17, 2018

Slide Decks:

Description: This free webinar will share information from four companies that offer PFAS treatment technologies for drinking water utilities. State drinking water programs will learn more about the different PFAS removal/treatment technology options and considerations for water systems in their state. State, interstate, tribal, and federal water program personnel are encouraged to attend, along with anyone else who would like to participate.

Webinar Agenda:

  1. Purolite: Jord Yniguez, the Applications Engineer, will share information about Ion exchange resins such as the highly selective Purolite® PFA694E can remove both short and long chain PFAS compounds to non-detect levels. Purolite has data on several full scale and pilot scale systems which shows benefits over granulated activated carbon (GAC). Ion exchange resins have better PFAS removal abilities and cost saving potential in terms of both capital and operating costs over GAC. Ion exchange resins require shorter empty bed contact times (EBCT) and have high overall capacity for PFAS compounds which lead to smaller sized vessels and less frequent media change outs.
  2. Calgon Carbon Corporation: Eric Forrester, the Applications Engineer, and Alexandra Lynn, the Product Manager and Senior Process Engineer, will provide a review of Calgon Carbon’s extensive history and experience removing PFAS from water using Granular Activated Carbon (GAC) and Ion Exchange (IX) technologies. The technologies are evaluated for PFAS removal via lab, pilot, and full-scale performance data from waters around the country. The impact of media service life on long term project costs is reviewed, and the disposition of spent media (incineration, landfill, recycling, etc.) is considered.
  3. TIGG LLC: Karl Kuchling, Business Development Manager, will present the considerations that must be reviewed during the selection process of the media. Topics that will be covered include flow rates, water quality, surface vs ground water, pilot studies, mass transfer zone and when the media should be changed. Since TIGG uses the media that the other participants will be discussing, this presentation will be based upon the factors that go into providing a solution for each individual application.
  4. Evoqua Water Technologies, LLC: Caitlin Berretta, the Business Development Manager and John Lombardo, the Product Manager, for Environmental Solutions, will provide an overview of Evoqua’s approach to PFAS removal from water. This presentation will review the suite of PFAS technology capabilities including Granular Activated Carbon (GAC) and Ion Exchange resin as well as the pros and cons of each. Successful case studies from communities across the country will also be shared.
