Separation Techniques in Environmental Science

Separation and purification techniques is an important aspect in this modern era. It involved in separation and purification of homogenous and heterogenous mixtures to its purest form. Separation is the segregation of different types of solid waste at the location where they are generated (a household or business). The most common reason for separating wastes at the source is for recycling. To reduce the environmental impact of waste disposal, the Environmental Protection Agency (EPA) encourages communities to develop strategies to decrease landfill use and lower the risks and inefficiencies of incineration. Waste reduction and recycling are the most environmentally beneficial methods to manage waste. Increasing concentrations of greenhouse gases (GHGs) such as CO2 in the atmosphere is a global warming. Human activities are a major cause of increased CO2 concentration in the atmosphere, as in recent decades, two-thirds of the greenhouse effect was caused by human activities. Carbon capture and storage (CCS) is a major strategy that can be used to reduce GHG emissions. There has been an accompanying increase in interest in the academic community in environmental issues and research on ways to treat environmental problems. Separations could be used to concentrate contaminants for eventual destruction or immobilization and to remove contaminants and concentrate or purify them to the point where they can be used again and no longer be considered contaminants. Applications of separation methods are expected to increase as efforts are made to reduce waste volumes, reuse contaminants in inlet streams even further, or to remove containments from soils and groundwater.  Separation operations are currently important in almost every aspect of waste and environmental treatment. This track deals with techniques involved in separation and purification in various fields like green chemistry, radiology, containments of environment and instrumentation of the technique.
