Energooszczędne modyfikacje metod przeróbki osadów ściekowych

The cuts in energy consumption have directed the attention of environmental scientists and engineers to the problem of how to minimize the total energy demand in wastewater treatment plants. In the past decade, it has been not only the increasing number of wastewater treatment plants brought into operation, or the tough demands made on the quality of the effluents discharged into the recipients, but also the implementation of more effective technological trains that have noticeably increased the volume of the sewage sludge produced. The present paper provides examples of modernized technological trains enabling disposal of sewage sludges at reduced operating costs. Consideration is given to the importance of the power generation by the plant itself in the course of sludge processing, and to the problem of effective sludge management.
