In this webinar we are pleased to have a special presentation from John Freim, PhD, ZVI Product Manager and Director of Materials Science at REGENESIS. Dr. Freim discussed accelerated in-situ remediation using a synergistic combination of colloidal activated carbon and zero valent iron (ZVI).

Key topics addressed in this free webinar:

  • Colloidal ZVI enables co-application with colloidal carbon without inhibiting sorption and resulting in enhanced persistence

  • How the ZVI reaction pathway bypasses toxic daughter products

  • Modeled degradation and field case studies showing proven effective remedial performance of colloidal activated carbon when combined with colloidal, sulfidated ZVI
