Progress in the side-stream softening and purification treatment of industrial circulating cooling water systems

Literature of side-stream treatment of industrial circulating cooling water systems is reviewed and its functions are briefly introduced on the aspects of water saving,cost reducing,efficiency improving of water treatment and environmental pollution lowering. Units of lime- soda softening,weak acid resin softening and membrane separation are analyzed with their mechanisms,influential factors and research developments. Combined processes such as HERO^TM,electrodialysis zero-discharge,Hydronautics zero-discharge and tertiary side-stream treatment and their potential applications are discussed. Propsals of research direction and specific requirements of the side-stream softening and purification treatment are put forward for better fulfillment of further work in the study of industrial circulating cooling water systems.
