SafeGuard H2OTM

(An Intelligent Water Treatment System)
What does your technology do?

In-situ generation of stannous and tin dioxide for:

  • Domestic drinking water supplies (point of entry/use)
  •    Removes Pb, Cu, As
  • Groundwater Supplies (point of supply)
  •    Removes As, Cr (VI), Fe, Mn
  • Industrial and Mining Effluent
  •    Removes As, Cr (VI), Se, Hg, Cu
  • Cooling Systems
  •    Biocide and corrosion inhibition
  • Domestic drinking water networks
  •    Lead corrosion inhibition, biocide
  • Industrial air emissions
  •    Removes SO2 H2S, NOX

The SafeGuard H20 incorporates AMS's proprietary continuous, real-time monitoring of contaminant levels in influent and effluent to ensure optimal treatment and compliance with regulatory and operational targets 24/7/365.

What is the compelling value proposition?
  • Far more cost-effective treatment solution than traditional alternatives (tin and electricity are the only consumables)
  • Tin is non-toxic, safe to handle and stable
  • Generated in-situ as required (no chemical logistics and handling)
  • Automatic dosing controlled 24/7/365
  • Remote performance monitoring for unattended sites
  • Operates in continuous mode (vs batch)
  • Flexible configuration options - point of supply (POS)/point of entry (POE) point of use (POU)
  • Scalable from home use to flows of millions gallons/day
  • Filter backwash reuse in many applications
  • Filter sludge reuse in some applications
What problem did this aim to solve?
  • Lifetime costs of traditional treatment systems (membranes, media, chemical storage, handling, toxic waste disposal, skilled personnel) that limit their adoption, especially by small water treatment systems and non-PWS.
  • Lack of visibility of performance of traditional treatment systems. Integration of real-time monitoring into the stannous generator reduces the need for onsite trained personnel and ensures 24/7/365 compliance (not only when regulatory samples are being taken).
  • Increasing cost and environmental impact of use of orthophosphates for lead passivation at POS. Controlled stannous dosing at points of risk of lead corrosion displaces orthophosphates.
  • Cost of selenium and mercury waste disposal. Displaces expensive chemicals, recovery of non-renewable resource (selenium) and reduction in disposal costs of waste from traditional chemical treatment methods.
  • Lack of public funding for municipal water treatment projects. Intelligent treatment system supports toll pricing that will attract private funding.
What this means for the future?

There are no similar applications that integrate a low life time cost contaminant treatment system with real-time performance controls. SafeGuard H2O can serve:

  • 6 million homes in USA exposed to the risk of lead contamination
  • 400 wells in CA with >10ppb hexavalent chrome
  • Global tannery industry - major foreign exchange earner and source of local chrome contamination
  • The multi $billion worldwide market for cooling system anti-corrosion treatment
  • 750 active coal ash ponds (95% un-lined) in the USA containing mercury and selenium. 359 active coal fired power plants generating mercury and selenium
  • Thousands of groundwater wells in the USA, India, China, Pakistan, & Latin America with unsafe levels of arsenic can be treated cost effectively
