The cooling water system in water-cooled condensers can be divided into two categories:
I. Wastewater systems In wastewater systems, the cooling water absorbs heat in the condenser and is discharged into the gutter. When a wastewater system is used, the price of water and the source of water supply are important factors to consider because the water is discharged into the gutter.
