The primary objective of ATV-DVWK-A 131 E is to provide engineers with a steady-state approach to sizing biological reactors and secondary settling tanks. It is applicable to municipal activated sludge plants of any size, ranging from small local facilities to large-scale population centers. Key Design Parameters The standard covers the removal of carbon, nitrogen,

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.
