The guidelines are developed by experts, providing reliable technical data and design approaches.
It provides methods for calculating the anoxic volume and internal recirculation rates.
What does the ATV‑DVWK‑A 131 mean in practice? Here are some concrete applications:
The sizing of the aeration basin depends on the mass production of excess sludge and the specific oxygen requirements.
It is used globally for designing systems that handle low-temperature wastewater, showing that the principles can be adjusted to different climate zones. atv dvwk a 131 epdf top

The "ATV-DVWK-A 131" standard, titled "Dimensioning of Single-Stage Activated Sludge Plants" in its English edition, is a comprehensive technical guideline developed by the German Association for Water, Wastewater and Waste (DWA) [8†L4-L5]. It supersedes the older German industry standard ATV-A 131 [6†L8-L9].

The scientific rigor of ATV-DVWK-A 131 has influenced design standards worldwide. For example, when China revised its national code for wastewater treatment, "Outdoor Drainage Design Code" (GB 50014) , they incorporated technical principles and references from the German ATV standard. This makes the ATV-DVWK-A 131 an international benchmark, not just a German rulebook.
