• The formula is a further development of the German ATV - A 201 with aditional (empircal) parameters forTemperature (which was neglected in the current A 201)
• The FUCHS brothers have developed this (empirical) formula with data from Germany as well as from Mediterranean countries and practical experiences collected from other regions worldwide.
• A temperature coefficient is introduced, which allows improved pond design adapted to a greater range of climatic conditions (different from the current A 201).
• Additional design parameters are introduced with respect to the number of aerated ponds in series and the surface structure of the pond liner.
Methodology and preliminary ResultsAerated Ponds (empiric approach by FUCHS Enprotech GmbH)

Conclusion & Acknowledgement
• Successful Validation of design approach for faculative(with COD and Water Temperature). Continuation is needed with more data from various sites.
• Still in Process: Including one additional parameter for Insulation. First results are promising.
• Aerated Ponds: Successful implementation of additional design parameters: number of aerated ponds in series and the surface structure of the pond liner.
• Acknowledgement: The project is financially supported by the German Federal Ministry of Education and Research (www.bmbf.de; www.expoval.de/en) and co-financed by the industrialproject partner Fuchs Enprotec.
