Guidance on water conservation techniques of circulating cooling water in thermal power plants. | Status: Current

1 Scope This document provides technical and management guidance for water conservation of indirect open recirculating cooling water systems in thermal power plants. It is applicable to circulating cooling systems that use surface water, underground water, reclaimed water, and treated domestic sewage from thermal power plant as the make-up water and use physicochemical treatment methods to increase cycles of concentration, thus realizing water conservation and increasing water use efficiency. This document is applicable to recirculating cooling in thermal power plants fuelled by coal, oil, natural gas, and biomass.
