The primary purpose of the liner system is to isolate the landfill contents from the environment and, therefore, to protect the soil and ground wate...

The residues generated after SRF products account for 35–40% the input waste, and most them are finally disposed in landfills. flow management status were investigated, from using municipaland industrial respectively, separated by particle size. appropriate separation conditions according to characteri...

Between October 1982 and September 1983, an outbreak of cholera occurred in Transkei. A total of 678 patients with clinical illness were reported in a review of positive laboratory results.
