Dissolved Oxygen (DO)
PHi’s mixing technology uses compressed air for mixing a tank’s contents but does not add measurable DO.
It seems counterintuitive that introducing air into the tank would not increase DO. However, there are sound scientific reasons that prove the PHi mixing technology does not increase oxygen levels. Actual independent test results also show PHi does not add DO in anoxic mixing.
The GSEE oxygen transfer test can be viewed below. Specifically, see page 13, column 4.
An eight month test of mixing an anoxic basin for New York City provides scientifically measured testing and analysis, confirming that the PHi system does not add DO.
