At WABAG, we offer sustainable sludge stabilization systems designed to transform sewage treatment plants into energy-neutral facilities.
Our solutions contribute significantly to environmental protection while offering substantial savings in energy and costs.
In modern wastewater treatment plants, the focus is on producing virtually solids-free discharges. However, sewage sludge, a by-product of the treatment process, holds immense potential as a source of energy and nutrients. Correct treatment is essential, involving the reduction or removal of high water content, pollutants, pathogenic bacteria, and malodorous substances.
Our range of mature processes and plants enables the full exploitation of sludge potential. Two primary processes for correct sludge treatment include aerobic and anaerobic digestion. Depending on the individual demands made on a plant, an optimum result can also derive from dual stabilisation, which involves a combination of both processes.
Anaerobic sludge stabilization, particularly through our ENOPUR® system, offers a highly advantageous solution for sewage plants with medium to large design capacities. Controlled digestion results in combustible biogas suitable for energetic purposes. The ENOPUR® system encompasses anaerobic sludge stabilization, corresponding pre- and post-treatment steps, and nutrient recovery, providing advanced and sustainable sludge management solutions.
Anaerobic sludge treatment offers a range of ecological and economic advantages:
- A reduction in organic content of ~50% and its conversion into combustible biogas.
- The production of renewable energy
- The possibility of the independent supply of the treatment plants with energy
- Reduced operating costs
- A stable and reliable process
- A smaller footprint
- A reduction in the volume of malodorous substances
- Sludge hygienisation (including bacteria reduction)
- Climate protection through an improvement in the CO2 balance of the treatment plant
With extensive experience in the design, construction, and operation of anaerobic sludge stabilization plants across various regions, we provide comprehensive and individualized solutions.
