Page: 3. Aerobic-thermophilic sludge stabilisation
method is suitable for when decontamination is the objective. Good preliminary concentration is particularly important. Sludge which is produced is aerated in a closed tank (air or O{}2). When let out the sludge is conducted via a heat exchanger which preheats the freshly ...
