Convectional and Advanced Method of Industrial Waste Treatment

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.
