Harvesting bio-gas from anaerobic lagoon: a road to becoming energy positive
Melbourne Water’s Western Treatment Plant (WTP) is one step closer to becoming energy positive thanks to a new approach to anaerobic lagoon covers.
Although harvesting biogas from wastewater ponds for energy conversion is nothing new at the WTP, a unique and innovative design is helping capture more gas.
New covers have been installed at the plant’s 55 East and 25 West anaerobic lagoons. WTP Treatment and Resources Manager Jenelle Watson said the installations are part of a larger plan to convert biogas for energy use at the plant.
WTP Energy Futures Principal Ken Baxter said the lagoons’ unique configuration is helping the utility produce more gas, offering a strong case for expansion of its onsite power station.
