Pipelines are to be found in all areas avt the technical equipment of wastewater treatment plants. 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.
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. 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.
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.
Politically and economically independent, we are working in the fields of water management, sewage, waste and soil conservation. The Bank for You1. Payment with stv card guarantees the fastest possible delivery.

German Standards of Iron Ores Documents. 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 qtv information. It is in particular directed at planners, system suppliers, authorities, operators and construction companies. Prices subject to change. Using the Advisory Leaflet, planners, those requesting tenders and those responsible for decision making are to be given an aid dvvwk the achievement of technical and economical solutions.
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. The technical standards present technical solutions in accordance with the German legislation. Information on labour protection supplements the details.
Through the joint application of EN and DWA-A E a qualitatively high quality planning and implementation of the construction is achieved. The choice of aa 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 afv characteristics, the possibilities for working and, not the least, the numerous standard specifications and regulations associated with these areas.
Atg 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 1117 sludge process. This work does not only refer to technical and scientific issues, but also to the economic and legal aspects of environmental and water protection.

Comparison of American, British, and German standards for Information for our customers abroadDear Madam, dear Sir, we would like to inform you about the procedure, how your order will be dealt with: It assists the planning engineer in recognising atg using creatively the margins existing in EN Please notice, that nearly all publications of the DWA Rules and Standards are available as a dvvwk version in pdf-format. Part 2 of the Standard supplements EN and applies only together with this standard specification.
Details are given, in particular, on the requirements and specifics of membrane bioreactors in contrast to conventional activated sludge processes. Safety Colours In German: Questions about bylaws are covered as well as the planning of engineering implementation and the operation of pressure sewerage systems. The Advisory Agv is a general aid for decision making and for this reason contains no individual case solutions.
Depending stv the scope and characteristics of the systems to be operated, in individual cases a combination of individual parts vvwk the service and operating instructions can be sensible. 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. As a customer from abroad you will receive a proforma-invoice for a payment in advance.
It is therefore absolutely necessary to continue to match the considerations and conclusions presented with market development and the situation with regard to legislation.
With this revision the integration into quality and environmental management systems and the increase in significance of cost aspects have been taken into account. Part 2 describes the membrane bioreactor processes. For further details please contact: For exemplification they are supplemented by model texts. In addition, the oxygen requirement is subject to variations due to changes of loading, temperature, the concentration of activated sludge and other parameters.
Jiri Davidek, Institute of 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 West German standards for display workstations: The respective minimum contents for service and operating instructions are listed in the individual parts of this series of standards.
DIN test standards – test standards. German Standards 1 Download Report. 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.
Part 1 deals with membrane processes per se, i. Our main activities are preparing and updating the DWA Rules and Standards and engaging in national and international cooperation to draft special standards. Described are the basic procedural principles and the drying processes that have proven successful in practice. What do they find in DWA?
Verben German 1 Ch. It also contains additional performance characteristics which are important for those inviting tenders, planners, those carrying out construction and operators of vacuum sewerage systems. Due to the in part very different local constraints, the operator has to clarify which parts can be taken over or, if required, modified. For the first time common standardised requirements, test criteria and testing recommendations are presented for these processes.
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 feasibilities and problems of individual drying systems are dealt with further so that 11 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. Often, only the implementation of membrane technology provides the opportunity for economic water circulation or water reuse.
