A conceptual approach to selection of a control measure for residual chlorine discharge in Kuwait bay

It is estimated that some 17 metric tons of residual oxidants (chlorine) are discharged into the enclosed coastal seawater of Kuwait on a daily basis from power-desalination plants alone. Alarmed by the unlimited number of reported cases of damage to marine aquatic systems due to chlorine discharge around the world, several alternatives were proposed to control such a massive discharge of residual oxidant into seawaters. The objective of this article is to provide a conceptual approach that can be used to select a control measure for residual oxidant discharge in Kuwait coastal seawaters. This approach is based on state-of-the-art knowledge and the unique operational and environmental factors involved. A matrix system was designed whereby the cost of residual chlorine control alternative, its effectiveness, and environmental and public health impact, performance, and reliability in Kuwait can be compared and evaluated.
