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%.
