The City of Alamosa, Colorado, evaluated the SafeGuard™ H2O arsenic removal technology to replace the use of bulk ferric chloride. The evaluation demonstrated the technology’s ability to provide effective and reliable arsenic removal below 5 ppb with a ferrous dose of 6.5-8 mg/L that was generated on-site and on-demand. The demonstration also evaluated the purity of the in-situ electrogenerated ferrous reagent compared to bulk ferric chloride, showing SafeGuard™ H2O’s ferrous reagent precursor to be of higher quality.  Whereas bulk ferric chemicals often have significant levels of co-contaminants (e.g., manganese and other trace metals) that compromise treated water quality and the environment, the high purity of the electrode precursor material used in SafeGuard™ H2O has minimal and predictable effects and the produced reagent concentration is tightly controlled. As a result, SafeGuard™ H2O has numerous advantages over traditional coagulation processes that depend on bulk ferric chloride.  In this episode of AMS Talks, Industry Consultant Nadia Abboud speaks with Roy Sanchez, CWP, Water Plant Operator for the City of Alamosa, and Dr. Vladimir Dozortsev, Senior Product Manager for AMS, who discuss insights about this project and what prompted the City of Alamosa to undertake this arsenic removal demonstration.
