About Cooling Tower Cycles of Concentration Calculator (Formula)
A Cooling Tower Cycles of Concentration Calculator is an essential tool for engineers and facility managers to determine the efficiency of cooling towers in recirculating water systems. The cycles of concentration (COC) refers to the number of times water is cycled through the cooling tower before being replaced by fresh water. Understanding and optimizing COC is crucial for reducing water waste, minimizing chemical use, and improving overall operational efficiency. This article will explain the formula for calculating COC, guide you on how to use the calculator, and provide practical examples.
Formula
The formula for calculating cycles of concentration is COC = 500 ppm / 50 ppm, where COC represents the cycles of concentration, and the values represent the concentration of total dissolved solids (TDS) in parts per million (ppm) in the cooling water.
How to Use
To effectively use the Cooling Tower Cycles of Concentration Calculator, follow these steps:
- Measure the concentration of total dissolved solids (TDS) in the make-up water (fresh water) in ppm.
- Measure the concentration of TDS in the cooling tower water (after it has circulated) in ppm.
- Insert these values into the formula: COC = Concentration in the cooling tower water / Concentration in the make-up water.
- Calculate the cycles of concentration to determine how many times the water is cycled through the cooling tower.
Example
Suppose the concentration of TDS in the make-up water is 50 ppm, and the concentration in the cooling tower water is 500 ppm. Using the formula:
- Concentration in cooling tower water = 500 ppm
- Concentration in make-up water = 50 ppm
Calculating cycles of concentration: COC = 500 ppm / 50 ppm = 10
Thus, the cycles of concentration in this example is 10, indicating that the water is cycled through the cooling tower 10 times before being replaced.
