FEASIBILITY STUDY OF THE ICHKEUL LAKE ENVIRONMENTAL REMEDIATION TECHNOLOGY BY USING THE JOUMINE WATER RESERVOIR SEDIMENTS

Abstract

 In this paper, the effect of recycling Joumine water reservoir sludge for strength improvement of the bottom of the Ichkeul lake sediment using the natural ecosystem is evaluated, with a focus on the remediation of National Heritage Ichkeul National Park in Tunisia. The goals of strength improvements are to minimize erosion from sea waves and enable marine organism growth. The main conclusions of this study are as follows. 1) The Joumine water reservoir sludge ecosystem can be enhanced by improving sludge strength. 2) A crystallization of the calcite in the Joumine water reservoir ecosystem is promoted by adding urea and calcium chloride. 3) The proposed techniques can be implemented to improve the benthos growth.
