This is very interesting...

This suggests that you can simply add enough water to dilute the taste and smell.
Unfortunately, the current scientific, industrial, and medical use of chlorine dioxide recognizes that specific concentration is needed in order for it to be effective. They have run tests to determine the concentrations needed and offer guidelines for effective concentrations.
For example let's look at water purification.
Using chlorine dioxide to purify water requires a concentration of 4 PPM free chlorine dioxide and a hold time of about 4 hours.
Since the concentration (4 PPM) is directly related to the amount of water used, adding extra water would reduce the chlorine dioxide benefit. If you added extra water, you would end up with water that was not purified.
Chlorine dioxide works by having a concentration of it in contact with the pathogens for a specific amount of time. Jim Humble has stated that his goal is to have a dose that ends up with around 1 PPM free chlorine dioxide.
Since Jim Humble has offered no evidence to refute the scientific way chlorine dioxide works, we must assume that the above statement does not really mean what it says and that the concentration of chlorine dioxide is critical to its effectiveness.
