Comprehensive Study on Wastewater Treatment Using low cost Adsorbent

Water is a source of energy and life, although millions of people worldwide are suffering with the shortage of clean drinking and fresh water. Rapid pace of population expansion, industrialization and unplanned urbanization have largely contributed to the severe water pollution and surrounding soils. Discharge of toxic industrial wastes and untreated sanitary, dumping of industrial effluent, and runoff from agricultural fields can be the main sources of freshwater pollution. Apart from that, many solid wastes have been generated from burning agriculture solid waste used to generate electricity. Especially solid waste from rice mill, oil palm mill and power plant, these ashes are abundantly available in Malaysia. within the close to future, additional increase within the quantity of those waste materials is anticipated to occur, particularly in Malaysia, where rising economies are expected to provide the biggest increase in energy consumption. Therefore, makes an attempt are created to utilize waste materials as various adsorbents, particularly waste-derived siliceous materials.
