Retrofit Wash Water Recycling System
CUSTOMER: Multi-national Mining Company
LOCATION: Pilbara Region, Western Australia
Company profile
- This major iron ore miner exports to the world from mines in the WA Pilbara region
- Full site facilities to enable open cut mining
- Minesite requirement to manage dust and water usage
Business situation
The upgraded washbay required a compliant water treatment plant for water recycling. Monitoring equipment and incorporated programming was necessary for the overall integration of each facility supplying and drawing from the Water Treatment Plant.
Technical situation
The existing treatment plant could not remove the smaller solid particles that resulted in blocked spray nozzles. Additionally, the level of hydrocarbons present in the discharge water was above maximum levels of allowable discharge levels. This meant that the operation of the washbay was limited due to the cost of operation and lost opportunity to reuse onsite.
Solution
The system is completely automatic which enables a reliable outcome and reduced time by onsite staff to monitor the operation of the system.
Benefits & Impact
The commissioned HV Water Treatment Plant enabled the following benefits:
- Reduce water usage – potable water usage has declined with the incline of recycled water onsite
- Reduce running costs
- Risk reduction for environmental compliance
