The standard is structured to guide engineers through the entire design process, including:
: Sizing is heavily governed by the lowest operating wastewater temperature. At lower temperatures, the standard mandates an increased aerobic sludge age to prevent nitrification failure.

Sizing the aeration tank requires determining the exact sludge age (Solids Retention Time or SRT). Microorganisms must remain in the system long enough to degrade target substrates before they are wasted.
The guideline focuses on several critical aspects of wastewater treatment plant (WWTP) design:
used in wastewater treatment. "EPDF" typically denotes a downloadable electronic PDF version of this manual, which is widely used by environmental engineers to calculate sludge loads and oxygen requirements. It might be a German standard (ATV-DVWK) for

The standard represents a cornerstone in German wastewater engineering, providing the technical framework for the dimensioning of single-stage activated sludge plants. As part of the transition to the DWA-A 131 designation, this document outlines the rigorous calculations required to ensure environmental compliance and operational efficiency in modern treatment facilities. The Role of ATV-DVWK-A 131 in Engineering
The standard guides engineers on how to determine the incoming pollution load (COD, BOD, N, P) and hydraulic flow. It specifically warns about the impact of industrial discharges mixed with municipal sewage, ensuring that design parameters account for these "external" loads.
