Parker Hannifi n® TEMPERATURE EFFECT COMPARISON CHART
(At 820 psi & 35,000 ppm feedwater TDS conditions)
The Temperature Effect Chart on this page illustrates the loss or gain of productivity across the R.O. Membrane.
To determine what normal (in spec.) fl ow of the system is at 77º F (25º C), follow these directions:
1. Determine feed temperature.
2. Locate the corresponding temperature on the chart.
3. Follow the corresponding temperature in a vertical line up to the plotted production line.
4. From this temperature point at the production line, move left horizontally to the plotted productivity percent.
5. Calculate the system’s present productivity in U.S. gallons per day by multiplying the gallon per hour product water
fl ow meter reading by 24.
6. Divide the fi gure reached in step 5 above, present gallon per day productivity, by the plotted productivity percentage
from step 4 above. The answer will be equivalent to the membranes present productivity at specifi cation test
parameters, 820 psi & 77º F (25º C).
Example:
1. With the system operating at 820 psi (57 bar).
2. The present feed temperature is 61º F (16º C).
3. Plotted productivity is therefore 72% of normal.
4. The system is a 14,530 gallon per day model and it is presently producing 9,000 gallons per day.
5. 9,000 per day divided by .72 equals 12,500 gallons per day calculated productivity. The system is rated at 14,530
gallons per day ± 15% (12,350 to 16,709 gallons per day). Therefore the system is within specifi cations at 12,500
gallons per day actual productivity at 61º F (16º C), 820 psi (57 bar), and 35,000 ppm feed.
