Anaerobic wastewater treatment technology from Global Water Engineering (GWE) is helping companies generate additional income through green power generation.  

Traditionally, Australian industries have focused almost exclusively on treating their effluent to meet local discharge standards. Wastewater treatment installations have generated only costs and have never been seen as revenue generators.  

Applying anaerobic wastewater treatment however, sheds an entirely different light on the cost structure of wastewater treatment infrastructure as it can now become a substantial additional source of income for factories and processing plants.  

In addition to treating the water to regulatory requirements, GWE’s technology helps produce valuable biogas during the treatment process. In fact, for specific industry applications with high organic loads, sufficient biogas can be generated to fully cover a factory’s energy needs and still have a biogas surplus to feed into power generators and sell electricity to the national grid.   

The technology was recently applied to the new $120 million Bluetongue Brewery on the NSW Central Coast, where, in addition to providing advanced wastewater treatment and recycling, it is helping to produce methane to power a third boiler and reduce overall energy consumption by about 15%.  

The economics of GWE’s anaerobic wastewater treatment apart, there is also a clear environmental advantage in significantly reducing the factory’s carbon footprint not only by supplying renewable energy, thus reducing or even eliminating reliance on fossil fuels but also by replacing traditional, open methane-producing lagoons and power-consuming, sludge-producing aerobic WWTPs.  

GWE’s anaerobic wastewater treatment technology is suitable for the following industries:  

  • Beer and beverages
  • Food processing and canning
  • Snacks, confectionary and dairy
  • Fermentation industry
  • Biofuels
  • Pulp and paper
  • Agro and agro-processing industries
  • Petrochemicals
CST Wastewater Solutions represents GWE technology in Australia.
