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. New English version in preparation: In respect of storage places for dredged material, gravel pits or pits of atf sites, flushing fields and depositories still cover a significant portion.

What do they find in DWA? The Advisory Leaflet deals with the implementation of appropriate controls and regulations for oxygen transfer.

Service Instructions for the X of Wastewater Pumping InstallationsJune Additionally we may deliver a number of selected rules and standards in the following languages, e. German Standards atb Iron Ores Documents. Statements are to be seen as a snapshot, which corresponds with the current status of the framework conditions and represent a xtv opinion. Comparison of American, British, and German standards for 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 q associated with these areas.


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 Through the joint application of EN and DWAA E a qualitatively high level of planning and execution of construction work is achieved.

Part 2 describes the membrane bioreactor processes. Published dvwm Nov View Download 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 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.

The German Set of Rules and Standards offers the user operating abroad comprehensive information on and approaches to solutions, however one has to take into account the adaptability in respect of national laws within other countries. Safety Colours In German: Pipelines are to be found in all areas of the technical equipment of wastewater treatment plants. Using the Advisory Leaflet, planners, those requesting tenders and those responsible for decision making are dvdk be given an aid for the achievement of technical and economical solutions.

Dwvk feasibilities and problems of individual drying systems are dealt with further so that an appropriate and well founded decision for xvwk against the employment of drying plants will be supported and the possible selection of a drying system facilitated on a good ground.

Please notice, that nearly atc publications of the DWA Rules and Standards are available as a download version in pdf-format. Through the joint application of EN and DWA-A E a qualitatively high quality planning and implementation of the construction is achieved.


The Bank for You1. A complete overview of all download versions and further information can be found under www. It is in particular directed at planners, system suppliers, authorities, operators and construction companies.

As a customer from abroad you will receive a proforma-invoice for a payment in advance. The Advisory Leaflet is a general aid for decision making and for this reason contains no individual case solutions. It is therefore absolutely necessary to continue to match the considerations and conclusions presented with market development and the situation with regard to legislation.

West German standards for display workstations: 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.

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