Description

Given the water flow to be treated, the concentration of the sodium hypochlorite solution to be prepared and desired concentration of chlorine in water, calculates the sodium hypochlorite daily consumption (assumed solution concentration: 10%), the number of containers (50 kg each) to be stored and the dosing flow.
