Sewage Sludge Treatment

Cost and energy savings associated with the application of high-performance digestion

The incorporation of a high-capacity stage, based upon the principle of the Schwarting-Uhde process, into an existing sludge digestion installation has resulted in stable operation, associated with higher biogas production, improved degradation rates and reduced operating costs. Results obtained are effectively transferable to other sewage treatment plants handling different sewage sludges.
