Modernization of the sludge-biogas section of the Sewage Treatment Plant in Starachowice

As part of the contract, the sludge-biogas section of the sewage treatment plant in Starachowice was modernized. The modernization was aimed at improving sludge management, with particular emphasis on reducing the amount of sludge, the management of which is one of the main components of operating costs.

As a result of the technologies and devices used in the project (including centrifuges), the amount of sediment produced in the sewage treatment plant was reduced. The second important element was the installation of a cogeneration unit, which produces electricity and process heat as a result of burning biogas (obtained through fermentation in fixed dome digester tanks). Both elements are used for the sewage treatment plant’s own needs, which also reduces the operating costs of the sewage treatment plant.
