13. Environmental Impact of Cooling Water Treatment for Biofouling and Biocorrosion Control

Water cooling towers are major users of water worldwide. Industrial development has resulted in an increase in the use of water for cooling tower operations. This has led to an expansion of the demand for water and natural resources, particularly in threshold countries such as China, India and South Africa. It is well known that how we use water in industrial applications will drastically affect water quality downstream. What seems as an isolated incidence often results in a complex interaction and the negative effects may amplify each other. While the challenges for water management increase, there are opportunities to prevent destruction of the environment and the water source and in doing so create a sustainable environment for development and water use.
