The 'initial volume' in a water treatment system refers specifically to the quantity of treated water that exists before the addition of bicarbonate concentrate. This context is crucial because the 'initial volume' serves as a baseline measurement from which the treatment process and subsequent modifications can be evaluated.

Understanding this definition is essential for effectively managing water treatment protocols. The initial volume indicates how much treated water is available for further processing, which is necessary for maintaining proper chemical balances, such as when bicarbonate is added to adjust alkalinity or pH levels in the treatment system.

In water treatment processes, monitoring the initial volume helps ensure that the treatment system operates within its designed parameters, leading to more effective and consistent water quality outcomes. The other choices refer to waste water amounts, testing volumes, or chemical dilutions, which do not encapsulate the specific concept of 'initial volume' within the framework of treated water prior to further treatment adjustments.
