Anaerobic pre-treatment effects on the aerobic degradability of waste water sludge

Our goal was to contribute to the optimization of the sequential anaerobic and aerobic treatment by investigating the effect of anaerobic stabilization on the aerobic degradability of sludge. In our laboratory scale sequential anaerobic and aerobic experiments unstabilized, dewatered municipal waste water sludge and digested sludge were used. The degradation was calculated on the basis of comparing methane production expressed in COD in the anaerobic treatment or oxygen consumption during composting and the COD of untreated sludge. The effect of anaerobic pre-treatment on aerobic degradability was evaluated, which gives a good basis for the optimization of the combined anaerobic - aerobic sludge treatment. By implementing our experimental method data can be supplied incase of other raw materials as well to help investigate optimization of sequential anaerobic and aerobic treatments.

Like all public international law treaties, the Paris Climate Accords rely on national law for their implementation. The success of the agreement therefore depends, to a large extent, on the stepstaken or not taken by national governments and legislators as well as on the instruments and mechanisms chosen for this task. Against this background, the present article compares different approaches to the implementation of the Paris Agreement, using court decisions as a means to assess their (legal) effectiveness.
