Abstract The study demonstrates the efficiency of the soil aquifer treatment (SAT) towards removal of heavy metals within electroplating wastewater thereby rendering it suitable for ground water discharge. The unique proposition of this research is to use a combination of soil and adsorbent properties to enhance the remediation of heavy metals such as nickel, copper and zinc. A comparative study through statistical analysis is employed to illustrate the effectiveness of the various SAT systems build using various combinations of SM and SC soil types along with bioadsorbents such as eucalyptus leaves, sawdust and Mosambi peel. Further, the mass balance analysis of heavy metals is carried out to comprehend the course of expulsion. The study, through a statistical approach, endorses that the SAT in conjunction with adsorbent gives much better removal efficiency than the SAT without adsorbent. Additional removal efficiency of 14% to 30% can be achieved with introduction of adsorbents within the SAT system. The optimal removal efficiency of nickel, copper and zinc was observed to be at 87, 98 and 93% respectively when passed through the combination of SM soil with sawdust.

Removal Of Heavy Metals

Heavy metal contamination is one of the most important environmental issues. Therefore, appropriate steps need to be taken to reduce heavy metals and metalloids in water to acceptable levels. Several treatment methods have been developed recently to adsorb these pollutants. This paper reviews the ability of residuals generated as a by-product from the water treatment plants to adsorb heavy metals and metalloids from water. Water treatment residuals have great sorption capacities due to their large specific surface area and chemical composition. Sorption capacity is also affected by sorption conditions. A survey of the literature shows that water treatment residuals may be a suitable material for developing an efficient adsorbent for the removal of heavy metals and metalloids from water.

Removal Of Arsenic

ABSTRACTDust originated from the iron and steelmaking containing undesirable compounds are not completely recycled because affects the process efficiency. These types of dust represents an economical lost as a consequence of values contents. However, dust have been characterized physically and chemically in order to study their potential environmental applications, as the removal of arsenic in wastewater. The results shows that dust have a superficial specific area between 16 and 20 m2/g, values considered high, typical of a material with adsorbent properties. Representative results of different tests adsorption of arsenic in the material described indicate that it is possible to reduce the arsenic levels in up to 95% from an initial concentration of 1 mg/L of total arsenic. The results indicate that the iron and steelmaking wet dust may represent a new option as material for the removal of heavy metals in water treatment.
