Biotechnological processes can be established economically and ecologically advantageous for the substance recycling along with waste treatment. The center of interest hereby is the use of anaerobic or substance producing aerobic microorganisms. The best known substance recycling process of organic materials such as bio-waste or sewage sludge (as a kind of residual biomass) is the recovery of biogas as a renewable energy source.
By integrating further appropriate process steps, additional value substances such as fertilizer salts (from nitrogen and phosphate ingredients of sludge, sludge water and waste) can be recovered.
Sludge management on wastewater treatment plants
Our services in the area of sludge management on municipal and industrial sewage treatment plants cover various aspects and range from solutions for filamentous bulking and foaming, to process adaptation from aerobic to anaerobic sludge stabilization, to digester design and optimization of digester operation.
