Assessment of the Performance of Sediments and Scrap Rubber Layers to Filter the Leachate of Landfills

Abstract

The leachate from landfills is considered as a great danger to the environment and human health. This danger is represented in its toxic components. The major purpose of this project is how to get rid of the toxic materials by a collection of sediments, scrap rubber and geotextile layers. Ten (10) cells with different compositions were used in this process, and the physicochemical analysis were made on water resulted from filtration. And permeability test on all cells. The results show that the physicochemical factors reduce with the increase of thickness of sediment layer. The physicochemical factors of water resulted from the cells which contain scrap rubber with dimensions of 0.2mm are fewer than the ones with dimensions of 4mm. The permeability factor rise in all the cells with the increase of scrap rubber layer thickness of both types.Cell 5 with no scrap rubber gave better results in physicochemical factors but weak results in permeability factor. Cell 4 gave good results in both physicochemical and permeability factors

Dredged Dam Raw Sediments Geotechnical Characterization for Beneficial Use in Road Construction

“…The present study aims to assess the performance of dredged fine sediments from the Dam of Fergoug which are used as a pavement subgrade material. The valorization of dredged materials and their use in road pavement and in construction is a topic that has attracted the attention of an increasing number of researchers in recent years [12][13][14][15][16][17].…”
