“…The whole process is known as a liquid phase filtration because it separates a wide range of organic (uncharged) and inorganic particles from solutions . Notice that separation process is based on the molecular weight cut‐off (MWCO) or 300 to 500 Da .…”

Heavy metals like arsenic, copper, cadmium, chromium, nickel, zinc, lead, and mercury are major pollutants of fresh water reservoirs because of their toxic, non‐biodegradable, and persistent nature. The industrial growth is the major source of heavy metals introducing such pollutants into different segments of the environment including air, water, soil, and biosphere. Heavy metals are easily absorbed by fishes and vegetables due to their high solubility in the aquatic environments. Hence, they may accumulate in the human body by means of the food chain. Various methods have been developed and used for water and wastewater treatment to decrease heavy metal concentrations. These technologies include membrane filtration, ion‐exchange, adsorption, chemical precipitation, nanotechnology treatments, electrochemical and advanced oxidation processes. In this review, the methods as well as their mechanisms and efficiency are discussed.

“…Better retention was obtained at basic pH (up to 80% at a pH of 8). Ortega et al (2008) used two commercial nanofiltration membranes to remove metal ions from an acidic leachate solution generated from a contaminated soil using H 2 SO 4 as a soil washing agent. Ku et al (2005) studied the effect of solution composition on the removal of copper ions by nanofiltration.…”

The Integrated Environmental Technology Series addresses key themes and issues in the field of environmental technology from a multidisciplinary and integrated perspective.An integrated approach is potentially the most viable solution to the major pollution issues that face the globe in the 21st century.World experts are brought together to contribute to each volume, presenting a comprehensive blend of fundamental principles and applied technologies for each topic. Current practices and the state-of-the-art are reviewed, new developments in analytics, science and biotechnology are presented and, crucially, the theme of each volume is presented in relation to adjacent scientific, social and economic fields to provide solutions from a truly integrated perspective.The Integrated Environmental Technology Series will form an invaluable and definitive resource in this rapidly evolving discipline.

“…4 and 5 that the rejection efficiency of components of leachate-B is lower than that of leachate-A. The solute rejection decreases with increase in feed concentration, which is expected, in general, with RO/NF membranes (Murthy and Gupta, 1997;Peeters et al, 1998;Ortega et al, 2007Ortega et al, , 2008. It is a characteristic nature of the NF membrane and interpreted by screen phenomenon.…”
