6. APPLICATIONS
• Process & produced water disposal
• Tailings & storage dam overloading increasing risk
of catastrophic failure and collapse
• Legacy & mine closure site wastewater issues
• Landfill water management
• Closure of ash basins, dewatering
• Leachate water management
• Uncontrolled release of contaminated mine
water causing environmental harm
• Extreme rainfall events and flooding

27. ENVIRONMENTAL MANAGEMENT SYSTEM (EMS)
To maximise the performance of the MINETEK
Evaporators, a control system is available to
autonomously operate the Evaporators under varying
environmental conditions.
The automation systems are designed by MINETEK
and utilize high quality PLC’s, robust Australian made
weather sensors and high quality motor control
components to provide the tools necessary for
autonomous operation.
Automatic shut down due to:
• High humidity
• Rain
• Excess drift (high wind speed)
• Unfavorable wind direction
• Set time periods
28. AUTOMATIC ANGLE ADJUSTER (AAA)
The Automated Hydraulic Angle
Adjuster automatically adjusts the angle
of the Evaporator based on different
wind speeds.
This mechanism works in conjunction
with the EMS and provides flexibility for
the evaporator to operate in a broad
range of weather conditions.
