Case Study:

The Need: Provide filtered seawater for the mine

  • Utilizing treated seawater for all the mine’s production needs which are estimated at 68,000 m3/day of which 8% are desalinated utilizing Reverse Osmosis Membranes
  • Water is pumped to an altitude of 2,300 meters to the mine.
  • Requirement for a reliable filtering solution that can efficiently handle the large water capacity, high pressure and seawater conditions

The Solution: AF-900 Automatic hydraulic filters

  • Minera Esperanza selected the AF-900 Automatic electric self cleaning filter as the main UF pre treatment solution in the desalination project.
  • Filters constructed with seawater corrosion resistant materials and designed to operate with 25 Bar pressure
  • Design was according to ASME supervised by third party inspection (TPI)
