This paper describes in detail a case study that has involved the design, construction and commissioning of an SBR leachate treatment plant for Hampshire County Council, at Efford Landfill Site in the New Forest in Hampshire.
The plant was commissioned by the authors during early 2003, and incorporates a fully-automated SBR treatment process, with an engineered reed bed polishing system to achieve very high effluent quality standards. The plant is capable of treating up to 150 m3/d, and data are presented and compared with performances at other similar full-scale leachate treatment plants. The issue of residual “hard” COD in treated leachate, removal efficiencies by various processes, and toxicological implications of discharge of these materials, are specifically addressed. The paper is based on data obtained from a rigorous programme of monitoring and auditing of plant operation by the Council, during a period of more than 3 years, and these data are presented and discussed in detail.
Provision of reliable on-site leachate treatment is becoming the accepted standard at UK landfills, before high quality effluent is discharged either into the public sewer, or to surface watercourses. At many sites reliable and cost-effective biological treatment systems have been designed and installed, and aerobic biological processes are almost always adopted to provide such treatment. Almost all of these operate as Sequencing Batch Reactors (SBRs), the first such UK system having been designed nearly 25 years ago (Robinson and Davies, 1985), although treatment schemes are increasingly being supported by simple effluent polishing processes such as dissolved air flotation (DAF) or reed beds. This trend towards provision of full on-site treatment will undoubtedly continue, being increasingly driven in recent months by the requirements of IPC, which demand the application of Best Available Techniques.

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.
