Our guest speaker in this webinar is the esteemed Dr. John Freim, ZVI Product Manager and Director of Materials Science at REGENESIS. Dr. Freim discusses the benefits of using zero valent iron (ZVI) as a powerful remediation amendment.

ZVI can be used for the remediation of chlorinated hydrocarbons, pesticides, and other toxic substances in the soil and groundwater. Since the launch of S-MicroZVI™ in 2018, over 100 sites worldwide have been treated with this advanced In Situ Chemical Reductive (ISCR) technology.

In this webinar you will learn:

  • The concepts of how ZVI technologies work: in situ chemical reduction
  • The benefits of sulfidated, colloidal ZVI − supported by the latest research
  • The differences between S-MicroZVI and other products in the marketplace
  • What to expect when combining technologies:
    – PlumeStop and ZVI
    – ZVI-assisted bioremediation

The presentation is structured around the 4 amendment requirements for successful in situ remediation:

  • Reactivity – Reaction mechanisms of S-MicroZVI versus bare ZVI
  • Distribution – Buoyancy, mixing and injection behaviour of colloidal ZVI suspensions compared to large particle size ZVI
  • Persistence of S-MicroZVI and minimising passivation
  • Ease of Use – Mixing and injection protocols

Dr. Freim is joined by Gareth Leonard, Managing Director of REGENESIS in Europe.
