Innovations in sludge and biosolids treatment have put SUEZ on the forefront of the Resource Revolution. From recovery to disposal and agricultural uses, we are taking steps to refine the wastewater cycle so that all steps continue to provide clean, efficient solutions for all our customers.
Your challenges

The increasing volume of sludge produced by wastewater treatment, in line with population growth and urban development, is a major concern for local authorities and operators. Treating sludge to reduce volume and transforming it into recoverable products is critical to the environment. However, activated sludge plants occupy substantial masses of land, are costly to build and operate, and demand an enormous footprint.
Our solutions

Municipal leaders trust SUEZ to help them define and choose optimal sludge treatment solutions based on the sludge’s origin, composition and treatment by-products, as well as the sludge’s final destination, whether it will be recycled, recovered or destroyed.

Our solutions, which include sludge thickening, dewatering, digestion, drying and incineration, offer the following benefits:
• Increased dry content
• Long-term stabilization
• Optimal separation of water from matter
• Reduced weight and volume
• Easier recovery and disposal
• Recovery as green energy by generating biogas
• Reduced footprint and operating costs of facilities
