The water supply provider Sofiyska voda, part of Veolia group, had put into operation a new methane tank in the wastewater treatment plant (WWTP) of the Bulgarian capital, BalkanEngineer.com learned from a company announcement. The facility has a volume of 7000 m3 and is designed according to the latest technologies.

 

 

Thanks to the new methane tank, the WWTP of Sofia increased its capacity for green energy production by 25%. The advanced technological process used in it will guarantee reliable fermentation of sewage sludge and will generate larger amounts of biogas. The processed sludge will be characterized with higher parameters (less odors and more compact volume) and will be donated to farms for fertilization of industrial crops. The released methane will be converted into electricity and heat through co-generation.

 

The WWTP of Sofiyska voda processes over 350 000 m3 of wastewater per day. Since it has been in operation for over 30 years, the station has treated a total of over 4 billion m3 of wastewater, which is equivalent to nearly 8 full volumes of the main water source of the capital – The Iskar Reservoir.
