The world is currently experiencing a water crisis in terms of both quantity and quality due to water ever-growing demand in large-scale consumer sectors such as agriculture, industry and tourism. This crisis results from the increasing pressure on water resources brought about the world population growth, continued urbanization and rapid industrialization as sources of an increased release of contaminated water into watercourses. Faced with this worrying situation, strategies have been developed throughout the world for improving both the availability and access to water. Different technologies, both established and emerging ones, are utilized in view to treat wastewaters, including those of the mining origin. The present work reviews the different uses of water in the mining industry and identifies its different sources of polluted water. It analyses some wastewater treatment techniques and their applicability in the reclamation of wastewater generated by the DR Congo mining industry. The adopted approach, in dealing with the relevant issue of water crisis experienced worldwide in terms of both quantity and quality, is expected to help improving practices in the management of wastewater of mining origin, increasing access to water and its sustainable use.

“…The removal of cadmium from wastewater using cheaply available agricultural waste materials either in their natural or modified form has been widely reported in the literature (Jamali et al, 2009;Mahvi et al, 2010;Saikaew and Kaewsam, 2010;Mansour et al, 2011;Maleki et al, 2011;Umapati et al, 2011;Rahman et al, 2012;Al-Dujaili et al, 2012;Meneghel et al, 2013;Ossman and Mansour, 2013) have been evaluated for their biosorption properties. More and more interests are focused on developing these agricultural wastes as adsorbent or biosorbent for wastewater treatment due to their relative high sorption affinity, ubiquitous presence in the environment, and the ease of being modified to materials with higher efficiency (Li et al, 2010;Chen et al, 2011;Agarry and Aremu, 2012).…”

The biosorption potential of chemically modified onion skin (CMOS) for cadmium (II) ions (Cd 2+ ) from its aqueous solutions at different conditions of initial Cd 2+ concentration, contact time, pH and temperature was investigated under batch mode. The results showed that biosorption of Cd 2+ were influenced by these different conditions. The equilibrium biosorption data were analyzed by two-parameter (Langmuir, Freundlich, Temkin and Dubinin-Radushkevich (D-R)), three-parameter (Redlich-Peterson, Sips, Toth, and Khan) and four-parameter (Baudu and Fritz-Schlunder) isotherm models, respectively, using the linear and non-linear regression method. The best fitting isotherms to describe the biosorption data of Cd 2+ -CMOS system were found to be Freundlich, Sips, and Fritz-Schluender among the two-, three-, and four-parameter models, respectively. A maximum biosorption capacity ( max Q ) of 18.34 mg/g was obtained forCMOS as compared to 11.90 mg/g for raw onion skin (OS). The biosorption kinetics followed pseudo-second-order kinetic model and the biosorption mechanisms controlled by boundary layer surface diffusion. Thermodynamic parameters of Gibbs free energy ( o G ∆ ), enthalpy ( o H ∆ ), entropy change of biosorption ( o S ∆ ), and activation energy Downloaded by [Erciyes University] at 22:55 25 December 2014 ACCEPTED MANUSCRIPT ACCEPTED MANUSCRIPT 2( a E ) have been evaluated and was found that the biosorption process was spontaneous, feasible, endothermic and predominantly of physisorption process, however, with some element of chemisorption. A single-stage batch adsorber was designed for different biosorbent dose-to-effluent volume ratios using the Fritz-Schluender equation. The CMOS could be regenerated and reused till five cycles without any significant change of efficiency. Therefore, CMOS has potential for application as an effective biosorbent for the removal of Cd 2+ from aqueous solution.

The recycling of chemical containing glass bottles is generally not recommended due to high health risk. In this study, used glass ampoules were devitrified into a porous material by coprocessing with eggshells, salt, and soda at different temperatures. In this thermochemical reaction, eggshells decomposed into calcium, porogenic gases, and char. The calcium worked as a flux in the reaction while char and gases promoted the porosity of the devitrified glass. The thermochemically processed glass was treated with deionized water to clear the water‐soluble fractions and to improve the surface porosity. The final product was characterized for its chemical composition, functional groups, surface morphology, and pore sizes. The porous product revealed the pore volume of .010 cc/g, surface area of 32.0399 m2/g and pore radius of 1.522 nm. The well‐known Freundlich and Longmuir models were used to investigate the adsorption of blue dye onto the prepared porous glass adsorbent. The adsorbed amount of dye was found influenced by the contact time, adsorbent dose, pH of solution, and dye concentration. The porous glass adsorbed about 2.788 mg/g of dye at pH 2, which decreased to 1.938 mg/g at pH 7. The dye adsorption data followed the best fit for Freundlich model as compared to the Longmuir model.
