Strategies to cope with the emerging waste water contaminants through adsorption regimes

Mining wastewater treatment technologies and resource recovery techniques: A review

“…Thus, an adsorbent with properties such as high porosity (high surface area ≡ high absorption capacity), high selectivity, enough active sites on the surface, a short adsorption period, and high stability is more desirable [ 82 ]. Furthermore, the sorption process depends on the pH, contact time, adsorbent dosage, and temperature of the feed [ 83 , 84 ]. Some of the adsorbents that have been used for the treatment of wastewater include agricultural waste, biosorbents, industrial waste, miscellaneous sorbents, and natural materials [ 74 ].…”

“…At the laboratory scale, one of the frequently investigated removal methods is the adsorption process ( Table 3 ). And this might be due to its ease of design and operation, wide range of available adsorbents, less energy required, flexibility, and cost-effectiveness [ 84 ]. Just like biological and chemical precipitation processes, the adsorption process produces sludge and the regeneration of spent adsorbent is energy-consuming, insufficient, and results in high costs [ 114 ].…”

Development of Artificial Geochemical Filter to Treat Acid Mine Drainage for Safe Disposal of Mine Water in Salt Range Portion of Indus Basin—A Lab to Pilot Scale Study

“…Dissolution of CaCO 3 is a complicated process, whereas "n" is an integer with a value of 1 (first order model) or 2 (second order model). Thus, integration of Equation (10), being first order, yields the following Equation (11):…”

“…Contamination of freshwater resources caused by anthropogenic factors is a major issue in many areas, and is associated with mining activities. Mine water, irrespective of its neutral or alkaline nature, has the propensity to dissolve metals, and the resulting metal contaminants, such as Copper, Cadmium, Iron and Sulphur, have potentially harmful impacts that are not limited to chemical, physical, and biological spoliation of soil and water bodies; their adverse consequences on human health are undeniable [10]. Higher concentrations of Iron (Fe) and Manganese (Mn) in water bodies associated with mining sites have adverse effects on indigenous public health, including lethargy, hepatic necrosis, tachycardia, shock, hypotension, metabolic acidosis DNA damage, and in severe cases, even death.…”
