Ultrafiltration Plant and Membrane Bioreactor
Oil and Gas
Port Moresby, Papua New Guinea
BACKGROUND
Exxon Mobil’s PNG LNG Project required a Potable Water Treatment Plant (PWTP) and a Wastewater Treatment Plant (WWTP) to service the 630 man permanent facilities compound in Port Moresby.
Recognising MAK Water’s expertise in design and manufacture of high quality, fully automated, packaged water and sewage treatment plants for Oil and Gas projects, the construction contractor engaged MAK Water to design and construct the plants. Further to the offsite manufacture and supply of the plants, site installation and commissioning assistance, and a service agreement to support the facility operator were also provided.
SOLUTION
A containerised Ultrafiltration (UF) plant to produce 165 m3/day of potable water, and a containerised 500 m3/day membrane bioreactor (MBR) sewage treatment plant.
Potable Water TREATMENT plant
- Containerised UF plant with two 100% trains
- Raw water pH correction and chlorination systems
- Treated water hardness and chlorination systems
wastewater treatment plant
- Containerised MBR plant with two 50% trains
- On-board sludge dewatering and drying
>70% Dry Matter (DM) - Odour control and auto-membrane integrity testing
- Storage tanks by Coerco for raw sewage and treated effluent
design features
- 30 year structural design life
- 20 year mechanical and electrical design life
- Seismic design to Section 8 of AS1170.4: 2007
RESULTS AND BENEFITS
- Ease of installation. Prefabricated interconnecting piping and cabling, for easy reassembly on site.
- Safe and compliant. Safe and reliable potable water supply and treated effluent for guaranteed compliance.
- Training and operational support. Comprehensive training and documentation was provided and remote monitoring and routine service visits guaranteed the ongoing performance of the plants.
