  • Wetlands act as valuable urban water treatment

    As cities and urban landscapes expand across the globe, water resource management continues to pose a huge challenge. Natural wetlands are often built over as cities grow, but a recent strategy of green infrastructure applies the opposite principle – wetlands are protected and constructed as part of city planning. Wetlands, whether natural or man-made, act as large-scale storage and ...

  • Seasonal movement of trace-element discharge in a typical south-Indian suburban community

    Four conventional activated sludge sewage treatment plants (STPs) in Southern India were chosen to investigate the occurrence of major ions and trace metals in dissolved fraction of the wastewater. Samples were collected from inlet and outlet of STPs during the pre-monsoon and monsoon seasons. Except for a few elements (Mn, Mo and Ni), the concentrations of the rest increased at the outlet of ...

  • Why Everyone Should Drink Filtered Water

    Your body is made up of a lot of water; 60 to 65 percent to be exact. The water that you drink each day helps to replenish your body and give you strength. But, if you’re drinking water that contains heavy amounts of chemicals, metals, and other harmful ingredients, what does that say about your body composition? Untreated water could be responsible for a number of different health and ...

  • Cut-Off Wall - Abandoned Mine Tailings Pond - Case Study

    Problem At an abandoned mine in the Yukon Territory, mining for both Gold and Zinc took place until the mid 1950's, with the processing of the ore taking place on the banks of an adjacent lake. Processing methods resulted in the creation of a large mine tailings pond that had high concentrations of iron, arsenic, zinc and lead. Spring runoff and summer rainfall then infiltrated through ...

  • Monitoring the effectiveness of advanced sorption materials for removing selected metals from water

    There are a number of ways to remove heavy metals from water. Sorption on granular media based on iron oxides and hydroxides is currently the most used option. The experiment was carried out using sorption materials GEH, CFH 0818, CFH 12 and Bayoxide, which are primarily designed to remove arsenic from water. Four columns were prepared with an inner diameter of 4.4 cm for the purpose of the ...

  • Augmenting granular activated carbon with natural clay for multicomponent sorption of heavy metals from aqueous solutions

    Multicomponent adsorption of Cd, Cr, Cu, Pb and Zn onto date palm pits based granular activated carbon (GAC) augmented with highly active natural clay at different proportion was investigated. The effects of the initial pH and the adsorbents mixed ratio on the removal selectivity sequence of the metals evaluated. Batch adsorption experiments were undertaken at initial pH 2, 6 and 12. At ...

  • Multi-metals column adsorption of lead(II), cadmium(II) and manganese(II) onto natural bentonite clay

    The present work was aimed at evaluating the multi-metals column adsorption of lead(II), cadmium(II) and manganese(II) ions onto natural bentonite. The bentonite clay adsorbent was characterized for physical and chemical properties using X-ray diffraction, X-ray fluorescence, Brunauer-Emmett-Teller surface area and cation exchange capacity. The column performance was evaluated using adsorbent ...

  • Characteristics and adsorption study of the activated carbon derived from municipal sewage sludge

    Sewage sludge-based activated carbon is proved to be an efficient and low-cost adsorbent in treatment of various industrial wastewaters. The produced carbon had a well-developed pore structure and relatively low Brunauer-Emmett-Teller (BET) surface area. Adsorptive capacity of typical pollutants, i.e. copper Cu(II) and methylene blue (MB) on the carbon was studied. Adsorptions were affected by ...
