The standard is a globally recognised guideline for the dimensioning and design of single-stage activated sludge plants . Developed by the German Association for Water, Wastewater and Waste (formerly ATV-DVWK, now DWA ), this document provides civil, environmental, and chemical engineers with a highly structured mathematical framework to size aeration tanks and secondary clarifiers. It addresses carbon elimination, nitrification, denitrification, and biological phosphorus removal to ensure municipal and industrial wastewater facilities comply with strict environmental regulations.
