<p>The world
increase in population has lead to an increase in industrial activities that
has added so much load to aquatic bodies thereby increasing the risk on both
aquatic organisms and we humans in general. Technology, particularly in terms
of performance and available waste-water treatment options, has developed in
parallel with economic growth. However, technology cannot be expected to solve
each pollution problem. Typically, a wastewater treatment plant transfers 1 m3
of wastewater into 1-2 litres of concentrated sludge. Wastewater treatment
systems are generally capital-intensive and require expensive, specialised
operators. Therefore, before selecting and investing in wastewater treatment
technology it is always preferable to investigate whether pollution can be
minimised or prevented. For any pollution control initiative an analysis of
cost-effectiveness needs to be made and compared with all conceivable
alternatives. This chapter aims to show convectional method of treatment as a
good option to remediate waste water from industries. </p
