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 Atv Dvwk A 131 E.pdf
This detailed distribution enables highly accurate predictions for daily excess sludge production and exact oxygen transfer requirements. 3. Secondary Settling Tank Depth Zoning
Specific calculations for denitrification and nitrification processes. The standard is available for purchase and download

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 standard is highly technical and broken down into several key design areas: A. Input Data and Load Calculation
