In this study the potential of household waste charcoal has been determined as low cost adsorbent for the removal of heavy metals (lead (II) and silver (I)) from the industrial effluents with a double objective of solid waste management for improved treatment of waste water. The household waste activated charcoal and zero valent iron nano-particle doped household waste activated charcoal is synthesized and checked for its removal efficacy for heavy metals lead and silver in laboratory and is characterized using FT-IR, powdered XRD and AFM analysis. The comparison of the affecting parameters...

World is facing a rising epidemic of global environmental problems. Modern communication has brought us into a closer contact with every part of the world; we are compelled to recognize that all the Earth inhabitants share a common environment and its related problems. With the onset of industrial revolution in 1700s, increasing use of fossil fuels has resulted in enormous emissions of Carbon Dioxide into the atmosphere on burning. The increasing domestic and industrial energy demands coupled with an increase in the technological abilities has strengthened our potential for altering the...

Advanced oxidation processes (AOPs) are now believed to be superior in treating industrial effluent, especially effluent of textile industry because of their several advantages over other treatment techniques, including conventional and biological treatment methods. In this study, an attempt has been made to assess the efficiency of AOPs, including Hydrogen Per Oxide alone, Fenton, Photo-Fenton, Solar Radiation assisted Photo-Fenton and Ozonation for the color and COD removal of textile effluent. AOPs are proven to be the efficient method for the treatment of textile effluent. The performance...

The removal of heavy metals from the wastewater is a matter of concern for many countries but is a key issue in developing countries like Pakistan. These heavy metals are of serious health and environmental concern and there is a need to discover new and effective methods for their removal from industrial effluents. Removal of Copper (Cu) and Nickel (Ni) from industrial wastewater was studied using metal oxide nanoparticles such as magnesium oxide (MgO) and zinc oxide (ZnO). The metal oxide nanoparticles provide high adsorption capacity, simple operation and rapid adsorption.

Water is a valuable product, which should be used carefully. Increased global consumption of water has become a growing concern from a few decades, which has increased the demand of water recycling and reuse of waste-water by treating it with appropriate methods and technologies to meet the needs and aspirations of future generation. The reuse and recycling of laundry waste-water was carried out at lab scale. In this study, two random laundries were selected. A survey of PU and LCWU hostel laundries was made to characterize the laundry waste-water. A low cost sand and gravel filter was...
