waterStrider’s Advantages

  • Major operational, environmental and cost benefits over conventional systems
  • Small, modular and scalable
  • Fully-equipped pilot facility in Vancouver, BC
  • Lack of competition with novel, viable and cost-effective technologies

Examples of Very Large Mines in Canada with Water Treatment Needs

NWT, Canada

Giant Mine

 

  • Massive volumes: arsenic, acid
  • waterStrider beats all other systems - removed 99.6% arsenic
  • Remediation costs estimated $4.4 billion
  • Existing iron + lime water treatment does not work when freezing (~8 months per year)
GiantMine
FaroMine

Yukon, Canada

Faro Mine

 

  • Massive volumes: zinc, lead, acid
  • waterStrider beats all other systems - removed 99.9% zinc, 99.9% lead
  • Remediation costs estimated $2 billion
  • Existing lime water treatment does not work when freezing (~8 months per year)

BC, Canada

An Active Coal Mine

 

  • Massive volumes: selenium, acid
  • waterStrider beats all other systems - removed 99.5% selenium
  • Existing microbial water treatment cost over $600 million
  • Same selenium problems across all coal mines in Western Canada
