Membrane Bioreactor (MBR)
Pilbara, Western Australia
Karratha is the powerhouse of Western Australia’s Pilbara region. In 2009, the Airport commenced a $100m redevelopment, which included the installation of a new packaged sewage treatment plant.
The plant was required to treat sewage generated in the terminal to achieve “risk category high” compliance values, in accordance with the guidelines for Non-Potable Use of Recycled Water in Western Australia, to enable onsite reuse for toilet flushing, landscape irrigation and for the automatic car washing facility.
MAK Water was engaged by the hydraulic services contractor to carry out the design, manufacture, commissioning and WA Department of Health (DoH) validation of the plant. MAK Water was subsequently awarded a five year contract to operate and maintain (O&M) the plant on behalf of the City of Karratha.
Membrane Bioreactor (MBR) to treat 200 m3/day of sewage to “Risk Category High”, validated and DoH approved for “risk category high” reuse, with 5 year O&M agreement.

RESULTS AND BENEFITS
- Safe, compliant effluent. UF membranes provide a physical barrier to viruses and pathogens, as well as suspended solids. The chlorination system includes tank recirculation and online analysers for monitoring of free chlorine, pH and turbidity.
- Reduced potable water consumption. It makes sense, commercially and environmentally, to reuse treated wastewater for non-potable applications.
- Project compliance. MAK Water met the project specifications and Department of Health requirements for risk category high reuse.
