Desal Plant Profile - Gold Coast Desalination Plant
Labelled aerial photo of Gold Coast Desalination Plant Labelled aerial photo of Gold Coast Desalination Plant
Total capacity: 133 ML/day
Date commissioned: February 2009
Feed water TDS: 34000 mg/L - 39000 mg/L [1]
Product water TDS: 140mg/L [2]
Percent of water supply: 27% of South Eastern QLD
feed water temperature (low): 17°C
Feed water temperature (high): 28°C
Seawater intake system: Submerged open sea
Pretreatment system: Ferric sulphate coagulation, sulphuric acid injection (pH reduction), polyDADMAC, dual media pressure filters
RO operating pressure: First pass RO operating pressure - 64 bar (45% recovery). Second pass - 15 bar (85% recovery) [3]
RO passes: 2 [3]
RO trains: 9, 3
Post-treatment system: Lime stabilization, CO2, disinfection by sodium hypochlorite injection
Concentrate disposal: Treated supernatant discharged to sea, solids centrifuged and landfilled
Energy consumption: 3.58 kWh/m3
Energy recovery: Each RO train is fitted with dual-work exchanger energy recovery devices, which recover up to 97% of unused energy from the brine. Renewable energy certificates are being used to fully offset carbon emissions from the plant.
Capital cost: $1200 million
