Water Disinfection: A Practical Approach to Calculating example calculations of chlorine dosage Cutting
C = 2.75 parts per million (HOCl is 87% of free chlorine at pH 7.0). It is common for pH to increase to 8.5 during hypochlorite treatment, resulting in C = 41 parts per million (HOCl is 17.5% of free chlorine at pH 8.5). It is important to remember that test kits for measuring free available chlorine File Size: 35KBPage Count: 4TECHNICAL GUIDELINES FOR DETERMINING Examination of Water and Wastewater to determine the initial chlorine dosage. It is important to note that inorganic compounds found in groundwater such as iron, manganese, and sulfides will initially reduce the chlorine residual (i.e. create a chlorine demand), and these must be accounted for when determining the initial dosage.Sizing Chemical Feed Pump  VitasalusExample: 1.5 gallons per day ÷ 24 hours per day = 0.06 gallons per hour 0.06 gallons per hour x 3 hours per day (pump usage) = 0.18 gallons of solution used per day

Pool Chlorine Calculator
Check pool chlorine levels often. Chlorine is the most popular disinfectant for swimming pools. There are three main measurements for chlorine, Free Chlorine(FC), Combined Chlorine(CC), ad Total Chlorine(TC). Free Chlorine is most commonly tested because it represents the amount of chlorine free for disinfecting. Chlorine is very effective at eliminating most microorganisms in the water that example calculations of chlorine dosage Cutting5/5(1)Category: Pool Chlorine CalculatorOperating System: Windows, OSX, Android, IOS, LinuxModule 25: HypochloriteA.
