The German plant manufacturer, WELTEC BIOPOWER is supporting Yarra Valley Water for the refurbishment of its 1-megawatt biogas plant in the north of Melbourne. The output of the plant, which has two 530-kilowatt CHP units, covers the energy requirements of the biogas plant. The electricity generated is able to power both the facility itself and the sewage treatment plant, with excess energy is exported to the electricity grid. The plant has a processing capacity of 33,000 tons of organic waste from food processors and restaurants to generate around 7,500,000 kilowatt hours of energy per year.
At the start of the maintenance work, the tanks will first be completely emptied. In addition, the roofs of the two 3,573 cubic meter stainless steel fermenters and internal plant components such as the agitator technology will be replaced. The plant will then be commissioned and operational management will be secured. The digester contents will be temporarily stored in the storage tank and material can be filled back into the tanks after the refurbishment so the plant can be up and running quickly. This saves resources and costs.
