Status of Task
Result 3 is the development of a national sludge management strategy. In respect of this the following tasks from the ToR have been completed:
The results and conclusions from this work were compiled into a preliminary report (12th November 2022) and delivered to AKUM.
Further work on Result 3 is now conditional upon approval of the Result 1 report (see above).
Two particularly critical weaknesses of the present system have been identified:
The preliminary report covers the following aspects of sludge management:
It concludes that at present there is no regular recording of either the quantities or disposal routes for sludge in Albania. The preliminary assessments given in the report are presently being refined on the basis of the information contained in the Result 1 report (see above).
This section of the preliminary report provides a brief review of sludge management solutions (treatment and use/disposal) for small, medium and large-sized WWTPs focusing on successful (and unsuccessful) approaches adopted in the Balkans region. The intention is that this should be taken into consideration when deciding what may or may not be applicable to the varied conditions in Albania.
One notable conclusion is that none of the solid waste incinerators presently in use, under construction or planned in Albania would be suitable (for technological reasons) for the co-incineration of sewage sludge.
