Our biogas plants use a digester through-flow procedure, which involves the operation of one or more digester through which substrate is continuously fed. The digester and storage containers are stationary, cylindrical containers made of reinforced concrete with an integrated wall and floor heating system. The exterior walls of the digesters are thermally-insulated and lined with trapezoid bodywork.The size, quantity and equipment of the digesters depend on the type and quantity of the input substances being treated.

Powerful pumps or apparatus are used to load the raw materials. The digesters are fitted with up to four stirring devices and double membrane roofs for the purposes of gas storage and protection against weather.

After several cleaning processes, the biogas is converted into electrical and thermal energy in an electric generator. Part of the electrical and thermal energy produced is used for the energy and heating needs of the biogas plant itself, the rest is fed into the public electricity network and it is used to heat residential homes and buildings as well as agricultural or industrial processes with high thermal energy requirements.

Planning

Based on a detailed questionnaire, Biogas Nord draws up the optimal design for the plant, including a comprehensive profitability analysis tailored to the specific plant. This gives the site owner a breakdown of the required investment, the expected biogas and energy production and the expected profitability of the biogas plant. Then implementation plans for the construction of the plant on the premises are drawn, and the necessary approval documents which provide support for public funding applications are compiled.

Permitting

Biogas Nord draws up the implementation plans for the construction of the plant on your premises, compiles the necessary approval documents and provides support for public funding applications. In this way Biogas Nord relieves you of the responsibility for drawing up the documents permitting the construction and other legal and administrative procedures, and administers the approval process right up until the granting of approval.

Construction

Nord’s team of qualified and experienced personnel made up of engineers, biologists, business management specialists and technicians accompanies you every step of the way, from the planning phase to construction, down to the commissioning of the biogas plant.

Biogas Nord assumes responsibility for the full implementation of the entire construction scheme with its own project and construction managers and competent and experienced assembly teams.

Commissioning and Start up

Once the building of the plant is completed, the plant undergoes the start-up phase. The optimal substrate composition is found. Then bacterial flora is developed with injected serum slurry, the fermenter is heated externally, and the feeding quantities and times are adjusted.
