Regenerative Energie
Processwater from an organic waste biogas plant was treated in a two step biological wastewater treatment system. With a plant combination of storage tank, SBR (aprox. 100 L), sand filters (2x0.825m2) and recirculation several operational adjustments were tested during one year. The oxidation reduction potential (ORP) gave typical signs for a stable nitrogen removal without nitrite problems although ammonium inflow concentrations of up to 1.260 g/m3 are reached. An optimized operation was possible with the control of inflow amount, recirculation rate, aeration time and if necessary addition of a carbon source. Microbiological analyses with FISH and CLSM indicated the existence of a high amount of Nitrospira and Nitrobacter bacteria in the sand filter. High mean removal efficiencies were reached for COD 82%, NH4-N 98% and NT 90%.

In the context of the European Climate Law (EU) 2021/1119), the Governance Regulation (EU) 2018/1999 and the Nature Restoration Regulation (EU) 2024/1991, the KAnG came into force on July 1, 2024.
Transformatives Klimarecht: Raum, Zeit, Gesellschaft

This article contends that climate law should be conceived as inherently transformative in a double sense. The law not only guides the necessary transformation of economy and society, but is itself undergoing transformation.
