Brackish Water Reverse Osmosis (BWRO) and Membrane Bioreactor (MBR)
Mining
Pilbara, Western Australia
BACKGROUND
A Tier 1 mining company was set to construct a world class 500-room FIFO mining camp with resort-like rooms and multi-purpose courts for basketball, tennis and volleyball, a football oval with goal posts, cricket nets, a mini golf course, a fitness park with outdoor gym facilities and a wellness loop with running track.
MAK Water has been a long term and trusted supplier to this client, and we worked cooperatively with their internal project delivery team during the budgeting phase. Once the project was given the go-ahead, MAK Water was subsequently awarded the contract to design, manufacture, supply and commission both the potable water plant and sewage treatment plant to serve the large camp.
SOLUTION
Potable water plant comprising 240 kL/day brackish water reverse osmosis and a 200 kL/day Membrane Bioreactor.
ENGINEERING AND DESIGN REQUIREMENTS
- Detailed 3D modelling for human factors engineering
- Client specific drawing & data package
- Compliant with client preferred specifications
- Premium Instrumentation package with ClearAccess remote monitoring
- Insulated & air conditioned for hot Pilbara climate
CONTAINERISED POTABLE WATER PLANT
- pH correction, disinfection and anti-scalant dosing
- Two stage brackish water reverse osmosis (BWRO)
- Separate after-treatment and distribution pump setups for potable and irrigation streams
SEWAGE TREATMENT PLANT
- Inlet works/screening, with flow balancing and mixing
- Corrosion resistant PE bioreactors, with aerobic, anoxic and MBR zones
- Containerised ancillary equipment and control system
RESULTS AND BENEFITS
- Informed Buyer Model. A fit-for-purpose solution that complies with client specifications in a commercially sensible manner.
- Pre-tested, modular design. Plants were fully assembled and factory tested, and supplied with prefabricated interconnecting piping and cabling for easy site installation.
- Lowest operating cost. Plants were designed to minimise operator intervention, and fitted with remote monitoring and control capabilities.
