The is an indispensable tool for designing efficient and compliant wastewater treatment plants. Its rigorous approach to biological nutrient removal, sludge age management, and secondary settling ensures that plants can meet modern ecological standards.

The successor standard, DWA-A 131, further refined the design rules based on operational experience from numerous large-scale plants. The most significant changes in the 2016 version included: The standard is widely respected for its detailed

The ATV-DVWK-A 131E standard serves as a comprehensive guide for dimensioning single-stage activated sludge plants, focusing on calculating sludge age, oxygen input, and reactor volume for nutrient removal. This standard allows for conservative design sizing using either COD or BOD metrics, providing reliable treatment performance. For detailed calculations, the DWA-developed Activated Sludge Expert software can be utilized, as found at DWA-Software ResearchGate ATV-DVWK-A 131E: Sludge Plant Standards - Scribd

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. While specific features and specifications may vary, this
