However, is a known German association for water management and cultural engineering ( Deutscher Verband für Wasserwirtschaft und Kulturbau ), and "A 131" is likely a technical rule or guideline. But I can’t locate a real document “A 131 E” from memory. Could you confirm:
Documents like "Atv Dvwk A 131 E.pdf" are essential for several reasons:

The standard is primarily applied to municipal wastewater treatment plants, but it is often used for industrial sites with biodegradable wastewater.
The primary objective of the standard is to ensure that municipal wastewater treatment plants meet or exceed the effluent requirements established by the . It is widely considered one of the most adopted guidelines for wastewater design across Europe.
The German approach to wastewater treatment design is famous for its safety, operational reliability, and mathematical precision. The standard specifically focuses on handling domestic and municipal wastewater. It outlines an integrated design approach where the biological reactor and the secondary settling tank (clarifier) are calculated as a single, interdependent system. The structural breakdown of the document includes:
The standard, titled "Dimensioning of Single-Stage Activated Sludge Plants," represents a cornerstone in European wastewater engineering, particularly in Germany. Published in May 2000, this standard provides a comprehensive, scientific framework for designing activated sludge processes, focusing on oxygen transfer, biological nitrogen removal, and secondary clarifier design.
