"Standard guideline for the dimensioning and design of single-stage activated sludge plants, covering biological treatment, sludge age calculation, and oxygen demand. This is the English language version (E) of the German DWA-A 131 standard."

This standard is the definitive guideline used in Germany and widely in Europe for the . It focuses on biological treatment stages. Atv Dvwk A 131 E.pdf

Establishing design metrics like peak hourly flow, Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD), and total nitrogen/phosphorus loads.

Aeration systems must be dimensioned to meet peak carbon and nitrogen loads. The standard calculates the hourly oxygen consumption ( OUhcap O cap U sub h : Compare the ATV-DVWK results with other standards

) as the Primary Parameter : The design centers on the total sludge age or Solid Retention Time (SRT). The standard defines the minimum sludge age required based on the lowest operating temperature (

The standard integrates . With detailed parameters based on COD (Chemical Oxygen Demand) components, the 2000 version serves as a bridge between traditional static design and modern dynamic computer simulations, allowing engineers to create robust and adaptive treatment systems. It focuses on biological treatment stages

For professionals in the water and wastewater industry, is more than just a file name; it is the key to a world-class engineering standard. Officially titled ATV-DVWK-A 131E , Dimensioning of Single-Stage Activated Sludge Plants , this document is the English version of the German technical rule for designing the core of any biological wastewater treatment plant. It is a benchmark for engineering excellence, combining scientific theory with practical design.
