Sludge age wastewater treatment
WebbIt is hypothesised that very low sludge ages result in a selection of fast growing bacteria, which can utilise only part of the S (S) in the raw wastewater. The other part of S (S) therefore remains in the wastewater and can thus be utilised for enhanced denitrification in the second stage.
