Conversion of residues into an energy source
Sufficient wastewater treatment is a critical aspect of WABAG’s approach, and it encompasses a crucial component: Sludge treatment. During sewage treatment processes sewage sludge is produced as a by product. The resulting mixture of primary, secondary, and in some cases also tertiary sludge, known as “raw” sewage sludge, contains 0.5 to 3 % solids and poses potential health and environmental Hazards due to its pathogen content and decomposable nature. To mitigate these concerns, various treatment processes are employed to stabilize the sludge, decrease pathogen levels, and increase solids content, reducing its mass and size, and thereby reducing disposal costs. These processes are essential for managing sewage sludge effectively while minimizing its impact on health and the environment.

At the Rithala WWTP in India, WABAG introduced a “Waste-to-Energy” concept, modernizing and extending the plant with anaerobic sludge digestion and biogas utilization. Similarly, at the Şanlıurfa Metropolitan Municipality Wastewater Treatment Plant, advanced wastewater treatment is integrated with state-of-the-art sludge management, utilizing a large solar drying bed and biogas utilization to generate electricity and cover 75% of the plant’s energy needs. These initiatives elevate sustainability standards in wastewater management.
