Description
Given the flow to be treated, the desired dosing rates in pre and post-chlorination, and the concentration of the solution to be prepared, this method calculates:
- The daily consumption of calcium hypochlorite.
- The number of 40 kg containers consumed per day.
- The volumes of solution to be prepared daily.
- The maximum dosing flows.
It assumes that the active chlorine concentration in the supplied product is 65%.
