Kredo

The Lebanese Government is in the course of implementing a national plan of wastewater treatment plants construction. The sludges that will be produced by these plants have to be disposed of in the best economical and environmental ways. TECSULT/KREDO were commissioned to develop a master plan for the re-use or disposal of these sludges. Work consisted of reviewing the design of the existing and proposed treatment plants, the treatment processes, finding out the quantity, the quality, and the geographical location of the sludges produced, investigating the most useful ways of disposing of these sludges by using them as fertilizers, or disposing of them as solid waste. Legislative frameworks and international standards were reviewed and their applicability to the Lebanese conditions was assessed. Technical as well as economic feasibility studies were carried out and a decision making support tool was developed for the CDR on a GIS support platform.
