These plots indicate that the removal efficiencies of total iron in both Concrete Waste (CW), Brick and Mortar Waste (BMW) and Roofing Waste (RW) have reached its maximum values and remained more or less constant, while that in Flooring Waste (FW) slightly decreased with contact time
Summary
Scarcity of water is the most significant water problem in the world [1]. The massive urbanization continuously releases toxic contaminants into the groundwater reservoir by domestic, industrial and mining actions [3], causing environmental pollution. In developing countries, the contamination of ground and surface water by landfill-leachate is a significant issue due to the large number of uncontrolled and semi-controlled dumpsites. The leachate is generated from rain water passing through the solid waste. It consists of different organic and inorganic compounds and heavy metals (Fe, Cu, Cd, Mn, Zn, Pb and As), which may be toxic to the living organisms and alter the present ecology [6]. Zhao et al [7] mentioned that most of heavy metal ions are toxic to living organisms; these metal ions are non-degradable and are persistent in the environment; the elimination of heavy metal ions from wastewater is important to protect public health
