SafeGuard™ H2O Intelligent Water Treatment System

The SafeGuard™ H2O system offers a low-cost, reliable remediation system proven to address a range of trace metal contaminants, including hexavalent chromium, lead, ionic mercury, and selenium.

The operation principle of the SafeGuard™ H2O system is based on a proprietary approach that generates on demand a stannous ion reagent in-situ via an electrolytic process. In fact, freshly generated stannous ion using tin metal precursor provides very accurate reagent dosing. This reagent poses no environmental and health risks.

Chromium Remediation

2CrO₄²⁻ + 3HSnO₂⁻ + 5H₂O = 2CrO₃³⁻ + 3Sn(OH)₆²⁻

  • Removal of Cr(VI) to < 2ppb
  • 50% the cost of traditional systems
  • Autonomous for 90 days

Lead Remediation

  • Lead corrosion inhibition
  • Displaces orthophosphates that generate algae blooms
  • Biocide removing and preventing biofilm
  • Localized to need (home, residential; zone)

Mercury Remediation

Hg²⁺ + Sn²⁺ = Hg⁰ + Sn⁴⁻

  • Removal of mercury from coal utility waste to < 1ppb
  • Selective
  • Recovers mercury
  • No toxic waste

Selenium Remediation

SeO₃²⁻ + 2Sn² + ≥ Se⁰ + 2SnO₂

  • Removal of selenite from coal waste pond to < 1 ppb
  • Selective
  • Recovers selenium
  • No toxic waste
