(now under DWA) is the German standard for the dimensioning of single-stage activated sludge wastewater treatment plants with secondary clarification. It is widely used in Central Europe and beyond as a benchmark for biological nutrient removal (nitrogen and phosphorus).
. It is a foundational document for environmental engineers designing municipal or industrial wastewater facilities to ensure efficient nutrient removal and sludge management. Key Components of the Standard Biological Reactor Sizing:
in wastewater treatment. Originally published in May 2000 by the German Association for Water, Wastewater, and Waste (DWA), this guideline provides the mathematical framework for sizing biological reactors and secondary settling tanks to ensure environmental compliance. The Story of a Design Standard
Perhaps the most technical feature of the standard is the adoption of the Muskingum-Cunge method for flow routing. This mathematical model calculates how a flood wave changes shape as it moves through a pipe network. This is crucial for preventing "water hammer" effects and ensuring that peak flows from different sub-catchments do not synchronize at a junction point, which is a common cause of urban flash flooding. atv dvwk a 131 epdf top

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 provides a deterministic mathematical methodology to dimension single-stage activated sludge systems. Unlike purely empirical approximations, this standard systematically links sludge age, operational temperature, organic loading, and specific nutrient removal requirements.
