PILOT PLANT DEMONSTRATION OF REDUCTION TECHNOLOGY DURING ACTIVATED SLUDGE TREATMENT OF WASTEWATER
The treatment and final disposal of sludge has been and continues to be one of the most expensive problems faces to wastewater utilities. Hence, minimization of excess sludge production seems necessary to solve the sludge problem strategically. This study evaluates a novel approach to reduce excess sludge production in activated sludge process, in which activated sludge process and thermal treatment below 100°C are combined. Performances of this process in terms of sludge production and treatment efficiencies are evaluated with an activated sludge pilot and compared to a parallel control line. All these results lead to the determination of the optimal operating conditions.
