Energy from wastewater

Unfolding the energy potential of wastewater and municipal sludge reducing grid dependency.

Energy recovery from organic pollution and sludge

We transform the challenge of wastewater into an opportunity for sustainable energy creation. Our state-of-the-art energy recovery solutions harness the untapped potential of organic pollution and sludge, converting them into valuable biogas. This innovative approach not only supports the environment by reducing greenhouse gas emissions and dependence on fossil fuels but also offers a cost-effective way to power your operations.

How does wastewater become energy?

Wastewater is converted into biogas, a clean, renewable energy source, through an eco-friendly and efficient process. Our technology harnesses the power of anaerobic digestion, where microorganisms break down organic matter in the absence of oxygen, producing methane-rich biogas.

This biogas is then captured, purified, and converted into electricity, heat, or biomethane, offering a versatile energy solution for industries and municipalities. Embrace sustainability, reduce greenhouse gas emissions, and achieve energy self-sufficiency with our innovative wastewater-to-energy systems.

Energy recovery from organic pollution and sludge

We are experts in recovering energy from the organic compounds in wastewater, organic waste, and municipal sludge.

In the food and beverage industry, we are the undisputed leader helping production sites to significantly cut down on the energy bill.

In the potato processing industry for instance, up to 60% of a potato processing plant's electricity needs is recovered from anaerobic digestion of wastewater and potato waste.

Recovering energy from wastewater

Diverse energy recovering systems are used to harness energy from wastewater, a cornerstone of sustainable environmental management. Our expertise lies in transforming wastewater into a valuable resource, not only safeguarding our precious water but also tapping into its latent energy potential.

Discover the various cutting-edge technologies and processes we employ to recover energy from wastewater, spotlighting the seamless blend of sustainability and efficiency that characterizes our solutions.

Energy from wastewater: BIOTIM® anaerobic reactor

The BIOTIM® anaerobic reactor portfolio includes solutions for treating wastewater with different ranges of organic load or dry matter content.

Where space is scarce, the BIOTIM® high-rate anaerobic tower combines high removal of organic load and high biogas yield with limited footprint.

For high-yield biogas with high-quality effluent recovery, the BIOTIM® anaerobic tower is a compact solution helping in limiting the energy and carbon footprint.

Energy from sludge: BIOTIM® Solids

Our BIOTIM® Solids sludge digester provides biogas while significantly reducing sludge volume. In the BIOTIM® Solids sludge digester, sludge is digested under mesophilic conditions. The recovered methane needs treatment before fueling the combined heat and power generation units.
