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%.
