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
