Key Difference â Aggregate vs Average Aggregate and average are two terms that are often used in calculations. However, these two terms mean two different things. Aggregate refers to the total sum of elements in a data set whereas average refers to the central value in a dataset. This is the key difference between aggregate and average. What Does Aggregate Mean? Aggregate is an adjective and a noun which refers to something formed or calculated by the combination of several separate elements.
Hypochlorous acid and hypochlorite ions, when combined, is known as free chlorine. Both of these establish equilibrium and are both temperature and pH dependent at 7.5 pH and 77Â°F (25Â°C). Hypochlorous acid is more potent than hypochlorite ions in terms of disinfection.
Combined Chlorine = Total Chlorine - Free Chlorine. 2.3 ppm (TC) measured from test kit - 1.5 ppm (FC) measured from test kit = 0.8 ppm CC. If the water has no chloramines, the answer to the subtraction will be zero (0) and a shock treatment is. not needed. This is a desirable level. After determining the level of combined chlorine in the pool water, the pool operator must determine the breakpoint chlorination for that value. The breakpoint chlorination value is 10 times the combined chlorine (CC) level.
