Objectives of the Research Project
According to the Technical Guidance on Municipal Waste (TA Siedlungsabfall), landfilling of sewage sludge is not permitted anymore since June 2005 due to the high contents of organic dry solids in the sludge. In addition, agricultural reuse of sludge evokes controversy, because of possible heavy metal accumulation in plants and soil. Therefore new treatment, disposal and reuse options for sewage sludge must be found.
The Seaborne technology presents a new option for the treatment and reuse of sewage sludge. Its objective is, on the one hand, an elimination of pollutants (heavy metals) and, on the other hand, the recycling of resources such as nitrogen and phosphorus. The recycling of phosphorus is of special interest, since it is possible to market it as a ready-to-use fertilizer product.
The objective of the project is, to investigate the efficiency of the Seaborne technology on municipal wastewater treatment plants. The investigation includes resource demand as well as product quantity and quality. Additionally it is to be determined, whether and how the operation of the wastewater treatment plant is influenced by the use of this technology. The results of these investigations will be used to determine the efficiency of the Seaborne technology and its possible application at other wastewater treatment plants.
