Some university libraries subscribe to the “DWA-Regelwerk” online portal. Students and researchers can download standards for free through institutional login. This yields a top-tier PDF without personal cost.
The sizing of the aeration basin depends on the mass production of excess sludge and the specific oxygen requirements.
Recommended denitrification efficiency: 70–80% for 5–10 mg/L ( NO_3-N ) effluent.
Typical ( f_D ) = 0.2 to 0.5.
