What are the advantages of a circulating cooling water system compared to a direct-flow cooling water system?
It is more economical when water diversion is inconvenient or costly
Conserve water resources and reduce environmental pollution
Compared to direct-current cooling water systems, circulating cooling water systems can save a large amount of cooling water. The higher the allowable concentration level, the greater the amount of water that can be saved, and the wastewater generated also decreases accordingly. Therefore, this is the cooling system that is most widely used and comes in the greatest variety of types at present.
Circulating cooling water can save a large amount of cooling water, and the amount of wastewater discharged is also reduced accordingly. So this is the most widely used and diverse type of cooling system currently, and direct current can be employed in areas near rivers and lakes.
Water resources are scarce; conserving water is the trend
The greatest advantage is water conservation, and in today’s world with scarce water resources, this represents a major trend
Direct-flow cooling systems require a source of water with relatively stable quality in order to function; for example, when seawater is used as the cooling fluid by the sea, materials that are highly resistant to wear and corrosion are needed (titanium is often used for this purpose)； In most cases, circulating cooling water is still required for system heat exchange. I recommend taking a look at the second edition of \"Process Water Treatment Technology\" by Zhou Benxing; after reading it, you will gain a deeper understanding.

Except for seawater, cold tap water is not allowed in most places in order to conserve water resources
