Solution for Sludge Disposal from Urban Wastewater Treatment in Kosovo

Session

Civil Engineering, Infrastructure and Environment

Description

The process of treating urban wastewater in Kosovo is at an early stage and the construction of wastewater treatment plants (WWTP) for cities with larger population is expected to be completed in the next five years which represents about 40% of the wastewater discharged into Kosovo's rivers. Along with the construction of WWTP, a challenge that is being considered is the treatment of the sludge that will be produced from such treatment plants. Sludge is the primary component generated from the treatment process. Inadequate management and treatment of sewerage can pose serious threats to the environment. Contrary to that, a proper management of the treatment process is essential in ensuring environmental protection and may also generate revenue. There are different approaches around the world for the sludge usage. The most applicable options for use are: Agriculture, Compost and Construction, Landfill and Incineration. According to statistics agency Eurostat, in 2015, most of European countries applied sludge in agriculture, but there is also a tendency to move to other options such as incineration. The application of sludge in agriculture requires rigorous conditions therefore, other options like incineration are becoming increasingly likely. Kosovo in the next five years is expected to produce about 2700 t/month sludge weight after dewatering and storage (DS 30%) for approximately 600.000 inhabitants. Application in agricultural is being considered as an option (Gjakova and Peja), however, the results of soil analysis indicate that in many areas such application is limited or not possible. According to these results there is an indication of where the sludge can be used in Kosovo and the construction of an incinerator should be considered as one other option, which would treat the part of the sludge that cannot be used in agriculture ore landfill.
