MWM Adds Equipment to Eco-Friendly Water Treatment Plant

Posted on July 10, 2009

MWM is supplying additional equipment to Helsinki Water, a wastewater management enterprise of Finland's capital. The German manufacturer will be supplying a 12-cylinder engine of the TCG 2020 series delivering an electrical output of approximately 1000 kW, with an efficiency of 41.3%.

The Viikinmäki plant was commissioned in 1994 with four engines from MWM: three gas engines and one gas/diesel engine. The plant processes the wastewater of about 780,000 inhabitants and of industrial plants, which adds up to 3.53 billion cubic feet a year. The fermentation in the purification process generates about 353 million cubic feet of sewage gas a year, which is used for the generation of electrical and thermal energy, covering 100% of the plant's need for heat and about 50% of the power needs.

MWM said that the on-site implementation of the project was taken care of by the Finnish company Sarlin, a partner also responsible for the handling of the ongoing maintenance agreements.

So far, MWM calculated that its gensets have been producing 16 GWh of eco-friendly electricity and about 26 GWh of eco-friendly heat per year.
