Details are given, in particular, on the requirements and specifics of membrane bioreactors in contrast to conventional activated sludge processes.

Part 1 deals with membrane processes per se, i. Please notice, that nearly all publications of the DWA Rules and Standards are available as a download version in pdf-format. Statements are to be seen as a snapshot, which corresponds with the current status of the framework conditions and represent a majority opinion.

For the first time common standardised requirements, test criteria and testing recommendations are presented for these processes. The feasibilities and problems of individual drying systems are dealt with further so that an appropriate and well founded decision for or against the employment of drying plants will be supported and the possible selection of a drying system facilitated on a good ground.

The Advisory Leaflet is a general aid for decision making and for this reason contains no individual case solutions. Service Instructions for the Personnel of Wastewater Pumping InstallationsJune Additionally we may deliver a number of selected rules and standards in the following languages, e.

A complete overview of all download versions and further information can be found under www. For further details please contact: Published on Nov View Download Described are the basic procedural principles and the drying processes that have proven successful in practice.

The installations for the oxygen transfer must therefore be so designed that, on one hand, peak requirements can be covered, on the other, with low loading, not too much oxygen is fed to the system.

German Standards 1

In addition they contain rules for action in operation and avoidance of accidents and hazards to health. It helps the planning engineer to recognize and use creatively the margins existing in EN Information for our customers abroadDear Madam, dear Sir, we would like to inform you about the procedure, how your order will be dealt with: Comparison of American, British, and German standards for Part 2 describes the membrane bioreactor processes.


With this revision the integration into quality and environmental management systems and the increase in significance of cost aspects have been taken into account. The Standard, along with the usual references to standards and definitions, contains the detailed system description of a pressure sewerage system.

Jiri Davidek, Institute of Verben German 1 Ch.

It assists the planning engineer in recognising and using creatively the margins existing in EN The choice of the pipe materials and the dimensioning of the pipelines with regard to diameter and wall thickness require a high degree of specialist knowledge, above all with regard to types of loading, the material characteristics, the possibilities for working and, not the least, the numerous standard specifications and regulations associated with these areas.

Questions about bylaws are covered as well as the planning of engineering implementation and the operation of pressure sewerage systems. Through the joint application of EN and DWAA E a qualitatively high level of planning and execution of construction work is achieved. In many cases proven solutions can be recommended, in other cases attention must be drawn to technical documents and regulations, in order to develop correct standards for the requesting of tenders and the implementation in plant construction.

The strategies listed, area-related strategy, multi-sector, condition strategy, asset value strategy, function-related strategy and fire brigade strategy are assessed with regard to suitability and practice. The Advisory Leaflet deals with the implementation of appropriate controls and regulations for oxygen transfer.

Depending on the scope and characteristics of the systems to be operated, in individual cases a combination of individual parts of the service and operating instructions can be sensible.

The respective minimum contents for service and operating instructions are listed in the individual parts of this series of standards. The aim is to ease access to sewage sludge drying processes for the planner and operator of sewage sludge treatment plants. West German standards for display workstations: 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.


Using the Advisory Leaflet, planners, those requesting tenders and those responsible for decision making are to be given an aid for the achievement of technical and economical solutions. In addition, the oxygen requirement is subject to variations due to changes of loading, temperature, the concentration of activated sludge and other parameters. The Advisory leaflet presents a summary of the state of the art and allows both, the general introduction to this topic and also further consideration of the system.

Standard DWA-A E supplements the standard specification in order to cover the necessary national [German] requirements. DIN test standards – test standards. We hope to find your understanding why we have chosen this form of order procedure. In the joint publication both sets of technical rules are printed completely in one synoptic directive, i. The Bank for You1. Politically and economically independent, we are working in the fields of water management, sewage, waste and soil conservation.

German Standards 1

Pipelines are to be found in all areas of the technical equipment of wastewater treatment plants. Atc is therefore absolutely necessary to continue to match the considerations and conclusions presented with market development and the situation with regard to legislation.

Our main activities are preparing and updating the DWA Rules and Standards and engaging in fvwk and international cooperation to draft special standards. German Association for Water, Wastewater and and Standards The technical standards present technical solutions in accordance with the German legislation. The topics consist of several parts.

This work does not only refer to technical and scientific issues, but also to the economic and legal aspects of environmental and water protection. German Standards of Iron Ores Documents. For exemplification they are supplemented by model texts.

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 dgwk set of rules and standards.
