Next Water Generation

On November 24, the technical coordinator of the LIFE ECOdigestion 2.0 project and process manager of the Quart-Benàger WWTP, María José Tárrega presented the latest technical results obtained in the project at the IX Conference on Management and Treatment of WWTP Sludge, organized by the Environmental Biotechnology group of the University of Barcelona. In this paper, the kinetics of manure degradation calculated from discontinuous tests carried out on a laboratory scale were presented. The kinetics have been calculated from two different methodologies, through the constant ks and through the Gompertz and NLS equation, obtaining as main results the optimal dose of manure in the digestate under study to achieve maximum production while maintaining the stability of the digester and a good adjustment of the kinetics to the empirical values.
