Abstract:
Adequate water is necessary for various uses for a rapidly growing population and is one of the major challenges in recent years. However, it is becoming an increasingly scarce and degraded through natural as well as anthropogenic sources. In the recent years different techniques are being used to remove water pollutants but adsorption is a technologically simple, efficient, cost-effective, and non-destructive technique. Activated carbon (AC) and zeolite is considered the most efficient adsorbent material for removing many types of pollutants from wastewater. AC-zeolite composite is non-toxic and low-cost material with high efficiency because of the porous structure and large surface area. In this study the composite material were incorporated in constructed wetlands for effective water treatment. Two wetland setups (vegetated and unvegetated) were designed in which AC, zeolite and their composite used as adsorbent materials. Pre and post treatment analysis of water samples were done to determine different water quality parameters (EC, pH, TDS, Na+,Cl-, K+, Ca2+, Mg2+, So42-) and heavy metal concentrations.The highest contaminant removal efficiency of >80% was obtained from the vegetated constructed wetlands incorporated with AC-zeolite composite which was significantly higher than the unvegetated wetlands (>60%) at P = 0.05 and the contaminantremoval efficiency of both the wetland structures were decreased over time. The outcome of this research will have excellent implication for national benefits.
