ATV-DVWK-A 131E (DWA-A 131) is the German technical standard providing a structured, mathematical framework for the design and calculation of single-stage activated sludge plants. Key updates in the standard focus on COD fractionation for biological modeling and enhanced phosphorus removal. To view a preview of the document, visit Scribd.

However, DVWK 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: Atv Dvwk A 131 E.pdf

The ATV-DVWK-A 131E standard is a comprehensive German guideline for designing single-stage activated sludge plants, focusing on biological reactor sizing and secondary clarifier performance. Published by the DWA, the 2000 standard provides detailed formulas for nutrient removal, sludge age, and design loads to ensure treatment reliability, particularly for cold climate conditions.
