8.2.2.1 %Rejectionmeasurement
For reverse osmosis (RO) applications, percent rejection is measured with conductivity to deter-
mine the ratio of impurities removed from product or permeate water to the total impurities in the
incoming feed water. The formula for obtaining Percent Rejection is:
[1–(Product/Feed)]X100=%Rejection
Where Product and Feed are the conductivity values measured by the respective sensors.
Figure 4.1 shows a diagram of an RO installation with sensors installed for Percent Rejection.

NOTE: The product monitoring sensor must be on the channel that will measure percent rejec-
tion. If the product conductivity sensor is installed in channel A, then percent rejection must be
measured in channel A.
8.2.2.2 CalculatedpH(Powerplantapplicationsonly)
Calculated pH may be obtained very accurately from specific and cation conductivity values on
power plant samples when the pH is between 7.5 and 10.5 due to ammonia or amines and
when the specific conductivity is significantly greater than the cation conductivity. This calcula-
tion is not suitable where significant levels of phosphates are present. The M300 uses this algo-
rithm when pH CAL is selected as a measurement.
The calculated pH must be configured on the same channel as specific conductivity. For exam-
ple, set up measurement ”a” on channel A to be specific conductivity, measurement ”b” on
Channel B to be cation conductivity, measurement ”c” on channel A to be calculated pH and
measurement ”d” on channel A to be temperature. Set the temperature compensation mode to
”Ammonia” for measurement ”a” and to ”Cation” for measurement ”b”.

NOTE: If operation goes outside the recommended conditions, a glass electrode pH measure-
ment is needed to obtain an accurate value. On the other hand, when sample conditions are
within the ranges noted above, the calculated pH provides an accurate standard for one-point
trim calibration of the electrode pH measurement.
