Best Management Practice #10: Cooling Tower

2021-1-16 · A key parameter used to evaluate cooling tower operation is "cycle of concentration" (sometimes referred to as cycle or concentration ratio). This is determined by calculating the ratio of the concentration of dissolved solids in the blowdown water compared to the make-up water. Because dissolved solids enter the system in the make-up water and

Cooling Tower Water Treatment – Cycles of

Cooling Towers dissipate heat from recirculating water that is run through cool chillers, air-conditioning equipment, or other process equipment. Heat is removed by the tower primarily as the result of evaporation. Proper treatment of the water that circulates through the tower is a key element relative to the thermal efficiency

Maintaining Cycles of Concentration - Boiler, Cooling

After examining what it means to "cycle up" water in a recirculating cooling tower system, last week our blog dealt with the system's Cycles of Concentration.Your water treatment specialist can help you determine what the maximum number of cycles is for your system. Once that is determined, the best method for maintaining this maximum number of cycles is an automatic control system that

COC - Cycle of concentration in cooling water system

2021-1-1 · In detail this means, in a open cooling water system there are usually cooling towers and consumers, such as heat exchangers or similar. The cooling water is circulated all the time. The cooling water leaves the cooling tower at a certain temperture and comes back from the consumers in a higher temperature. The difference of the temparatur, from outgoing to return water is called delta T.
