Mining Industry Needs & Technomap

Meeting your Needs

  • To improve productivity by treating water for requirements of production process
  • To manage environmental risks by treating contaminated water to achieve water quality suitable for reuse or for safe discharge into environment
  • To add value to the bottom line by treating sludge streams to recover suspended solids and dissolved constituents
  • To secure high quality drinking water, even at remote mining sites
  • To have robust and reliable equipment requiring no unplanned maintenance
  • To cope with production peaks while complying with stringent regulations
  • To guarantee long-term efficiency and costs through operation services

Examples of Products/Services Actiflo® for Heavy Metal Removal

Actiflo® is a compact high rate clarification system that uses microsand for enchanced flocculation and has been applied at mine sites for treatment of dilute surface water runoff. The use of the microsand results in a very small footprint, up to 20 times smaller than conventional clarification designs and it is highly efficient in the removal of finely divided particles, metal hydroxides and metal salts.

Key Advantages of Actiflo® are:

  • high efficiency treatment –removal rate of turbidity and TSS up to 99 %
  • efficient removal of metals
  • very small footprint • flexible –reacts quickly to changing flow rates and raw water quality while providing consistently high effluent quality
  • quick start-up time – less than 10 minutes
  • sludge treatability – sludge can easily thickened and dewatered
  • easy to operate and maintain – minimal operator attention required
