A waste water treatment plant is set to become self-sufficient in energy with the commissioning of a new 1 MW on-site power plant.
Yarra Valley Water, the Australian water supply and sewerage services company will see its Aurora, Melbourne, facility (pictured) use anaerobic digestion treatment to supply biogas to two on-site 530 kW MAN engines.
With ground broken on the plant construction, commissioning is due in the next 14 months by German biogas plant manufacturer Weltec and its project partner Aquatec Maxcon.
Two stainless-steel digesters in Aurora, each of which has a capacity of 3573 cubic metres, will be fed with 100 tonnes of organic waste a day. More than half of this amount will come from cafeterias and restaurants. The rest will comprise fats and oils, brewery and dairy leftovers, fruit and vegetable waste and sludge that will be pumped from the adjacent wastewater treatment plant.
