Regenerative Energie
Currently, the research in the field of coagulation/flocculation process is focused on the synthesis of new composite coagulants, which are constituted of inorganic and organic constituents, hence able to utilize within one reagent the advantages of both inorganic and organic components. Among the possible organic additives, an anionic polymer can be used, by introducing it into a pre-polymerised metal coagulant, based either on Al or on Fe.
In this study, a co-polymer of acrylamide and sodium acrylate is combined with two widely used Al or Fe based coagulants, i.e. Polyaluminium Chloride (PACl), and Polyferric Sulphate (PFS), thus producing novel composite coagulation reagents. The coagulants were characterised in terms of typical physico-chemical properties, such as the degree of polymerisation, pH, conductivity and turbidity. Finally, coagulation experiments (jar-tests) enable the comparable assessment/evaluation of coagulants efficiency, when treating model kaolin-humic acid suspensions, or pre-treated tannery wastewater.

Die innerstaatliche Umsetzung des Pariser Klimaschutzübereinkommens
- ein Rechtsvergleich

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.
