The ATV-DVWK-A 131E (2000) marked a fundamental change by allowing design based on load . The current 2016 standard (DWA-A 131) has completed this transition, requiring design to be based exclusively on COD . This shift is crucial because COD provides a more accurate and complete measure of the organic carbon available for treatment.

Formulas to determine the required oxygen input (OUR) to meet both BOD reduction and nitrification demands. 2. Secondary Clarifier Design The ATV-DVWK-A 131E (2000) marked a fundamental change
The primary objective of the standard is to ensure that municipal wastewater treatment plants meet or exceed the effluent requirements established by the . It is widely considered one of the most adopted guidelines for wastewater design across Europe. Scientific formulas for determining surface area and depth
Ensuring the capacity of the clarifier matches the sludge production.
