Cycles of Concentration
Cycles of concentration (CoC) refer to the ratio of dissolved solids in recirculating water compared to the make-up water added to replace losses from evaporation, leaks, or blowdown. Essentially, it measures how concentrated the dissolved impurities become in a water system, like a cooling tower or boiler. Higher CoC means less make-up water is needed, conserving water and reducing operational costs. However, if CoC levels get too high, the recirculating dissolved solids can lead to scaling, corrosion and fouling that can damage the system and reduce efficiency.
The key to optimizing CoC is balance. A good water treatment program can keep cycles of concentration at optimal levels that save on water costs without risking major water issues popping up in the system.
Why Do They Matter?
1. Efficiency and Cost: Higher COC means less make-up water is needed, conserving water and reducing costs. However, if COC gets too high, scaling, corrosion, and fouling can occur, damaging equipment and reducing efficiency.
2. Chemical Balance: Proper COC management helps maintain the right chemical balance, ensuring effective treatment while minimizing waste and keeping costs down.
3. System Longevity: By controlling COC, the buildup of minerals and corrosive agents is minimized, extending the lifespan of the system. The exact ratio will depend on the specific water of the system.
Manage your Cycles of Concentration to Maximize Efficiency
Properly managing cycles of concentration is essential for maximizing the efficiency, cost-effectiveness, and longevity of water systems. By striking the right balance, facilities can reduce waste, minimize environmental impact, and maintain optimal performance without costly damage or downtime. Effective COC control is a cornerstone of boiler and cooling water management practices.
