Operating the unit at more than 120% of rated capacity in low salinity water can damage the
membranes and will void the RO unit warranty.
3.4 TEMPERATURE CORRECTION FACTOR
As previously described, the output capacity of any RO unit is highly dependent on feedwater
temperature. To quantify this relationship, theoretical data has been utilized to develop Temperature
Correction Factors (TCF) to compensate measured flowrate to calculated flowrate at 25°C/77°F. This
allows the operator to establish the baseline flow for a given temperature, allowing more accurate
troubleshooting. The procedure for calculating the temperature compensated flow is as follows:
