anaerobic Digestion in the wastewater sector
Energy made from
sewage sludge
Sewage and industrial wastewater treatment plants have enormous energy potential. Sewage sludge, a byproduct of wastewater treatment, contains large amounts of organic matter that can be converted into valuable sewage gas through anaerobic digestion. WELTEC BIOPOWER develops custom solutions for using sewage sludge and industrial wastewater energetically, including optimizing digestion towers, co-digesting, and building complete sewage gas plants. The result? Lower operating costs, reduced greenhouse gas emissions, and increased energy self-sufficiency.
Individual concepts
DIGESTION OF SEWAGE SLUDGE AND INDUSTRIAL WASTE WATER
Using biogas from sewage sludge and industrial wastewater lowers operating costs, reduces emissions, and increases the energy self-sufficiency of sewage treatment and industrial plants. We use bioreactors with integrated gas storage for anaerobic digestion, which is an efficient alternative to aerobic processes or traditional digestion towers. Using stainless steel as a constructing material allows for cost-effective, individual solutions for populations of 10,000 or more that can be implemented quickly and integrated in a space-saving manner. We support you with tailor-made complete solutions from consultation and project planning to commissioning and plant service.

Technology makes
the difference
Stainless Steel Tanks with Modular Design
Our stainless steel bioreactors are at the heart of every plant. The corrosion-resistant material ensures stable and economical operation of your plant for decades, especially for demanding sewage sludge fermentation. Thanks to their special modular design, we can get your bioreactors up and running in no time. Our tanks are equipped with reliable components, many of which we have developed ourselves, including control technology that is compatible with other systems and can be flexibly integrated, as well as our own technologies for sludge thickening, gas treatment, and electricity generation.
Cost-effective and sustainable
When biogas plants make sense for sewage treatment plants
Wastewater treatment plants and industrial wastewater facilities are facing rising energy costs and stricter environmental regulations. Biogas plants that use anaerobic digestion to process sewage sludge offer an economical and sustainable solution. By using the energy from the sludge, wastewater treatment facilities can greatly decrease their energy usage—in many situations, reaching total energy independence.
The biogas produced during this process can be used to generate electricity and heat. The thermal energy can be used to heat digesters or for other processes.
At the same time, the volume of sludge is reduced, lowering disposal costs. Controlled anaerobic digestion prevents the uncontrolled methane emissions that would occur during open storage or landfilling, which is an important contribution to climate protection.
WELTEC BIOPOWER designs each plant individually, whether it's optimizing existing digesters, integrating co-substrates to increase performance, or constructing complete new digestion plants. Our reliable, low-maintenance technologies are designed for long-term operation. We support you from planning and permitting to commissioning.
