One of the major challenges facing mankind today is to provide clean water to the vast majority of the population around the world. The need for clean water is particularly critical in the third world countries. River canals, estuaries, and other water bodies are being constantly polluted due to indiscriminate discharge of industrial effluents as well as other activities, and natural processes (1). Freshwater is a finite resource, essential for agriculture, industry, and human existence. Without adequate freshwater supplies of adequate quantity and quality, sustainable development will not be possible. Water pollution and wasteful use of freshwater threaten development projects and make water treatment essential in order to produce safe drinking water (2). Demands to treat industrial and domestic wastewater to avoid environmental pollution, and contamination of drinking water supplies are national and international issues (3). The reuse of wastewater has become an absolute necessity. There is, therefore, an urgent need to develop innovative, more effective, and inexpensive techniques for treatment of wastewater.
