Low-Cost Adsorbents: Growing Approach to Wastewater Treatment鈥攁 Review
Industrial, agricultural, and domestic activities of humans have
affected the environmental system, resulting in drastic problems
such as global warming and the generation of wastewater containing
high levels of pollutants. As water of good quality is a precious
commodity and available in limited amounts, it has become
highly imperative to treat wastewater for removal of pollutants. In
addition, the rapid modernization of society has also led to the
generation of huge amount of materials of little value that have no
fruitful use. Such materials are generally considered as waste, and
their disposal is a problem. Also, there are some materials that are
available in nature that have little or no use. The utilization of all
such materials as low-cost adsorbents for the treatment of wastewater
may make them of some value. An effort has been made to
give a brief idea of an approach to wastewater treatment, particularly
discussing and highlighting in brief the low-cost alternative
adsorbents with a view to utilizing these waste/low-cost materials
