Details are given, in particular, on the requirements and specifics of membrane bioreactors in contrast to conventional activated sludge processes. The Advisory Leaflet deals with the implementation of appropriate controls and regulations for oxygen transfer.

Information on labour protection supplements the details. The respective minimum contents for service and operating instructions are listed in the individual parts of this series of standards. Part 2 describes the membrane bioreactor processes. What do they find in DWA? It is therefore absolutely necessary to continue to match the considerations and conclusions presented with market development and the situation with regard to legislation.

We hope to find your understanding why we have chosen this form of order procedure. Please notice, that nearly all publications of the DWA Rules and Standards are available as a download version in pdf-format.


Published on Nov View Download Described are the basic procedural principles and the drying processes that have proven successful in practice. For exemplification they are supplemented by model texts. Through the joint application of EN and DWAA E a qualitatively high level of planning and execution of construction work is achieved. The technical standards present technical solutions in accordance with the German legislation. Part 2 of the Standard supplements EN and applies only together with this standard specification.

Jiri Davidek, Institute of In addition they contain rules for action in operation and avoidance of accidents and hazards to health.

Through the joint application of EN and DWA-A E a qualitatively high quality planning and implementation of the construction is achieved. In cost-comparison calculations all follow-on2costs for depreciation, rate of interest, operation and preventative maintenance are to be incorporated.

Objective is to give the user an aid with the selection of a suitable control concept, oxygen transfer and information on the mechanical engineering equipment with the activated sludge process.

The topics consist of several parts. For the first time common standardised requirements, test criteria and testing recommendations are presented for these processes. Due to the in part very different local constraints, the operator has to clarify which parts can be taken over or, if required, modified. Our main activities are preparing and updating the DWA Rules and Standards and engaging in national and international cooperation to draft special standards.


Our intention is to provide for the public of English speaking specialists a picture of how, in Germany, technical standards on technicalscientific subjects are elaborated and combined into a common set of rules and standards.

Comparison of American, British, and German standards for This work does not only refer to technical and scientific issues, but also to the economic and legal aspects of environmental and water protection. It helps the planning engineer to recognize and use creatively the margins existing in EN Part 1 deals with membrane processes per se, i. Politically and economically independent, we are working in the fields of water management, sewage, waste and soil conservation.

The aim is to ease access to sewage sludge drying processes for the planner and operator of sewage sludge treatment plants. Safety Colours In German: Pipelines are to be found in all areas of the technical equipment of wastewater treatment plants. Thereby, the emphasis is on the process unit, consisting of the biological degradation in the aeration tank and the separation of the biomass by means of membranes.
