We hope to find your understanding why we have chosen this form of order procedure. The number of its members makes the DWA one of the largest organizations in this field in Europe, and its special expertise and competence give it a prominent place in standardization, professional training and public information.

This work does not only refer to technical and scientific issues, but also to the economic and legal aspects of environmental and water protection.

West German standards for display workstations: Please notice, that nearly all publications of the DWA Rules and Standards are available as a download version in pdf-format. It is therefore absolutely necessary to continue to match the considerations and conclusions presented with market development and the situation with regard to legislation. Prices subject to change. The Standard, along with the usual references to standards and definitions, contains the detailed system description of a pressure sewerage system.

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. 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.

It helps the planning engineer to recognize and use creatively the margins existing in EN As a customer from abroad you will receive a proforma-invoice for a payment in advance. It is in particular directed at planners, system suppliers, authorities, operators and construction companies.

After receiving your payment the ordered publications will be sent to you immediately together with an invoice receipt. The aim is to ease access to sewage sludge drying processes for the planner and operator of sewage sludge treatment plants. New English version in preparation: 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.


The topics consist of several parts. Special focus was put on dredged material from water bodies of the the German Federal states and municipalities as exemplified with the removal of sludge from ponds, lakes and storage reservoirs. German Association for Water, Wastewater and and Standards For further details please contact: A complete overview of all download versions and further information can be found under www.

German Standards 1

Part 2 of the Standard supplements EN and applies only together with this standard specification. 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.

For exemplification they are supplemented by model texts. Jiri Davidek, Institute of Through the joint application of EN and DWA-A E a qualitatively high quality planning and implementation of the construction is achieved.

German Standards 1

Described are the basic procedural principles and the drying processes that have proven successful in practice. With this revision the integration into quality and environmental management systems and the increase in significance of cost aspects have been taken into account. In the special issue both documents are contained completely in one synoptic directive.

In the joint publication both sets avt technical rules are printed completely in one synoptic directive, i.

Our main activities are preparing and updating the DWA Rules and Standards and engaging in national and international cooperation to draft special standards. Part 2 describes the membrane bioreactor processes. In cost-comparison calculations all follow-on2costs for depreciation, rate of interest, operation and preventative maintenance are to be incorporated.

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. In addition they contain rules for action in operation and avoidance of accidents and hazards to health. Dvqk addition, the oxygen requirement is subject to variations 1117 to changes of loading, temperature, the concentration of activated sludge and other parameters.


Standard DWA-A E supplements the standard specification in order to cover the necessary national [German] requirements. Our dvwj 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. Objective is to give the user an aid with the selection of dvdk suitable control concept, oxygen transfer and information on the mechanical engineering equipment with the activated sludge process.

It assists the planning engineer in recognising and using creatively the margins existing in EN Due to the in part very different local constraints, the operator has to clarify which parts can be taken over or, if required, modified. In respect of storage places for dredged material, gravel pits or pits of quarrying sites, flushing fields and depositories still cover a significant portion.

Part 1 deals with membrane processes per se, i. 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.

DIN test standards – test standards. Questions about bylaws are covered as well as the planning of engineering implementation and the operation of pressure sewerage systems. 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 Through the joint application of EN and DWAA E a qualitatively high level of planning and execution of construction work is achieved.

Verben German 1 Ch. The respective minimum contents for service and operating instructions are listed in the individual parts of this series of standards.
