Regenerative Energie
The causes of contamination originate in the water itself and on materials in contact with water. Drinking water is not sterile and does not have to be. Water treatment plants’ strategy consists in removing the nutrients that bacteria feed on to produce 'biostable†drinking water. This allows in many cases chlorination to be avoided. But it is known that even biologically stable drinking water with very low nutrient content still contains micro-organisms. These micro-organisms can multiply themselves if they encounter nutrients.
The quality of water in Germany is considered exemplary worldwide - at least up to the water meter. But with household installations a gray area begins. A wide variety of materials is used with quite a few of them supporting biofilm growth. As a consequence, disinfection measures are taken, stressing and, thus, ageing the materials. This study addresses the question in how far ageing might support further biofilm growth. The work is part of a joint research project conducted by five research institutes including the IWW Water Centre and 17 industrial partners under the coordination of Prof. Dr. Hans-Curt Flemming (University of Duisburg-Essen). It was funded by the Federal Ministry of Education and Research (BMBF) for four years. The results call for attention.

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.
