Compared with other drainage processes the investments can be considerably lower. New English version in preparation: Through the joint application of EN and DWA-A E a qualitatively high quality planning and implementation of the construction 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.


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

Jiri Davidek, Institute of Questions about bylaws are covered as well as the planning of engineering implementation and the operation of pressure sewerage systems. The Bank for You1. With this revision the integration into quality and environmental management systems and the increase in significance of cost aspects have been taken into account. Statements are to be seen as a snapshot, which corresponds with the current status of the framework conditions and represent a majority opinion.

It assists the planning engineer in recognising and using creatively the margins existing in EN German Standards of Iron Ores Documents.

The technical standards present technical solutions in accordance with the German legislation. In addition, the oxygen requirement is subject to variations due to changes of loading, temperature, the concentration of activated sludge and other parameters. Published on Nov View Download Part 2 describes the membrane bioreactor processes.
