but I hope that someone can explain it in Sesame Street language so I'll understand it.
I know it's an estimation and even then it might be far off the real numbers (but it's better than nothing), but how much CYA is oxidated by sodium hypochlorite on a daily base when the water temperature is about 28 degrees Celsius?
The calculated CA loss rate using equation 7 is 0.87ppm/day at 85°F and an average of 4 ppm av. Cl. Data obtained for a sample of swimming pool water (4 ppm av. Cl, 138 ppm CA) at the same temperature showed a lower decomposition rate of 0.24 ppm/day at a ten-fold lower av. Cl/CA mol ratio of 0.06.
Would it be safe to say that the oxidation is around 0.25 ppm a day?
