Reference Projects

Construction of biogas facility at the wastewater treatment plant
Project description: The project is intended to extract electrical and heat energy from the biological sludge contained in waste water using anaerobic digestion technology with the production of biogas to be furtherly burnt in the installed gas piston units. The project scope included construction of a biogas complex with the total digestion capacity 115 m3 per day, with the content of solid substance in the sludge 3 – 5,5% including the construction of a facilities complex for stabilizing the sludge (methane tanks), facilities for using biogas in heat and power engineering utilities of sewage treatment facilities.
The project scope included
  • construction of a biogas complex with the total digestion capacity 115 m3 per day, with the content of solid substance in the sludge 3 – 5,5%
  • the construction of a facilities complex for stabilizing the sludge (methane tanks)
  • facilities for using biogas in heat and power engineering utilities of sewage treatment facilities.
