Foto: Fritz Eberlein

The dimensioning procedure for nitrifying and denitrifying activated sludge plants is now based exclusively on the COD load, unlike in earlier editions that were based on the measured BOD5 load. Contains Process description, the design procedure and the design bases, as well as the calculation of the mass of the sludge and the design of the secondary treatment and sludge activation. Planning and operational aspects, scenario comparisons, the effect of further automation functions and operational management concepts are included.
