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%.

Die innerstaatliche Umsetzung des Pariser Klimaschutzübereinkommens
- ein Rechtsvergleich
© Lexxion Verlagsgesellschaft mbH (8/2024)
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.
