Venturi injectors boost DO in power plant process water

摘要

Recirculating cooling systems and nonpotable water reuse are becoming more common at power plants in many countries, dramatically improving the water use efficiency of energy generating stations. On the other hand, even where water reuse is improving - and especially where it isn't - the condition of water returned to the environment from power plants is of great concern to utility managers and government regulators. Because most nutrients, sediments, metals, and other impurities are removed prior to the use or reuse of the water, dissolved oxygen (DO) becomes a key focus when it is time to release water into rivers or streams.
