Abstract

Cambi SolidStream was developed to reduce the cost of handling and to improve the quality of anaerobically digested sewage sludge. Continuous efforts within R&D and preliminary testing have led to the first full-scale installation in Germany in 2014. Laboratory test procedures to assess the impact of the SolidStream treatment on different types of digested sludge were developed and successfully compared to full-scale results. Laboratory testing has indicated improvement in final dewatering of the digested sludge and a good biogas potential of the centrate recirculated back to the digester. The full-scale installation is now producing around 25% more biogas and a high quality cake at around 40-43% dry solids.
