What type of water treatment is commonly performed in once through cooling water systems?

In once-through cooling water systems, the primary focus is on maintaining water quality to prevent corrosion, scale formation, and biological growth. Screening removes larger debris and particles from the water intake before it enters the system, ensuring that the components are protected from blockages and wear. The addition of corrosion inhibitors is crucial since it helps to protect metal surfaces from corroding due to prolonged exposure to water and varying temperatures.

This combination of screening and corrosion inhibitors effectively prevents damage to the cooling system, enhances efficiency, and prolongs the operational life of the equipment. Other treatments, such as chlorination, are more suitable for recirculating systems where the water is reused multiple times, while heating and cooling cycles and desalination processes are not applicable in the context of once-through systems. Thus, the treatment method specifically designed to meet the needs of once-through cooling water systems involves both screening and the application of corrosion inhibitors.
