BACKGROUND
The owner of a new iron ore mine in Yilgarn, Western Australia required water treatment facilities for potable water, sewage treatment and heavy vehicle (HV) washbay wastewater treatment. MAK Water worked closely with the client to design a custom package of four (4) separate plants, providing the best possible water treatment solutions across the entire mine site.
MAK Water supplied a potable water treatment plant located at the iron ore mine to treat hypersaline bore water; a sewage treatment plant located at the camp; HV washbay wastewater treatment for removal of hydrocarbons; and additional disinfection and pH adjustment for water reuse in the washbay.
SOLUTION
Potable Water
Containerised Sea Water Reverse Osmosis (SWRO) plant designed to treat blended bore water with up to 59,200 mg/L of dissolved solids and produce 25 m3/day of potable water.
- Custom designed pre-treatment to suit poor quality bore water with high TDS, iron and manganese
- Multimedia filtration and additional DMI-65 media filtration with manual bypass line
- Chemical dosing: pH adjustment (2), chlorine (2), de-chlorination, anti-scalant
- Increased instantaneous capacity to improve plant performance and reliability
- Clean in Place (CIP) upgrade for improved membrane cleaning
- Potable tank recirculation and monitoring of free chlorine
- Containerised (1 x 40’) solution for easy installation
- Onsite plant commissioning and operator training
Sewage Treatment
Modular Activated Sludge Bioreactor (ASBR) plant designed to treat 25 m3/day of domestic strength sewage.
