Round shape cooling tower or Round Cooling Tower is the circulating water flow that is removed (usually discharged to a drain) in order to maintain the amount of Total Dissolved Solids,other impurities at an acceptably low level. Higher TDS concentration in solution may result from greater cooling tower efficiency. However the higher the TDS concentration.The water that must be added to the circulating water system in order to compensate for water losses such as evaporation, drift loss, blow-out, blow-down, etc.
The temperatures of the recirculating water, piping and heat exchange surfaces determine if and where minerals will precipitate from the recirculating water. Often a professional water treatment consultant will evaluate the makeup water and the operating conditions of the cooling tower and recommend an appropriate range for the cycles of concentration. The use of water treatment chemicals, pretreatment such as water softening, The evaporated water leaves its dissolved salts behind in the bulk of the water which has not been evaporated, thus raising the salt concentration in the circulating cooling water.
