The ATV-DVWK-A 131E standard defines a deep feature as the comprehensive, four-part calculation of secondary settling tank depths (
) crucial for designing activated sludge plants. This calculation, including sludge age and oxygen transfer, determines the functional hydraulic efficiency of the sedimentation process. Detailed design guidelines for this process are available in the ATV-DVWK A 131 E technical document. GERMAN ATV-DVWK - AquaEnergy Expo Knowledge Hub
The ATV-DVWK-A 131 E standard is a globally recognized guideline for the dimensioning of single-stage activated sludge plants. Developed by the German Association for Water, Wastewater and Waste (DWA, formerly ATV-DVWK), this document provides the technical framework for designing wastewater treatment facilities that meet strict effluent requirements.
The standard is available for purchase and download through the DWA Shop or can be accessed on document sharing platforms like Scribd. Core Purpose and Application
The primary objective of ATV-DVWK-A 131 E is to provide engineers with a steady-state approach to sizing biological reactors and secondary settling tanks.

ATV-DVWK-A 131 E is a foundational technical standard published in May 2000 by the German Association for Water, Wastewater, and Waste (ATV-DVWK, now DWA). It provides comprehensive guidelines for the dimensioning of single-stage activated sludge plants used in wastewater treatment. Purpose and Scope
The primary objective of the standard is to ensure that municipal wastewater treatment plants meet or exceed the effluent requirements established by the German Wastewater Ordinance (AbwV). It is widely considered one of the most adopted guidelines for wastewater design across Europe.
Application: It applies to single-stage activated sludge systems of any size, typically serving populations of 5,000 or more. The ATV-DVWK-A 131E standard defines a deep feature
Key Focus: The standard covers the removal of carbon, nitrogen, and phosphorus.
Planning Period: Facilities designed under these guidelines should ideally have a planning horizon of no more than 25 years. Core Components of the Standard

It looks like you’ve shared what seems to be a filename for a PDF, possibly related to a technical standard or document (the “A 131” and “DVWK” suggest it might be a German hydrological or engineering guideline — e.g., from the former Deutscher Verband für Wasserwirtschaft und Kulturbau).
However, there’s no actual text of a blog post here — just the filename.
If you intended to share a link or the content of a blog post that discusses that PDF, could you paste the text or the URL? I’d be happy to help summarize, critique, or discuss the post.
The ATV-DVWK-A 131E standard is a comprehensive German guideline for designing single-stage activated sludge plants, focusing on biological reactor sizing and secondary clarifier performance. Published by the DWA, the 2000 standard provides detailed formulas for nutrient removal, sludge age, and design loads to ensure treatment reliability, particularly for cold climate conditions.
