EXAMPLE
Determination of NWP on a Minimate TFF Capsule
Water filtrate flux rates were measured for a Minimate TFF
Capsule at TMP’s of 5, 10, and 15 psig. The temperature of
the water was 16°C. Determine the original normalized
water permeability (NWP).

Water Permeability =
110 LMH @ 10 psig = 11.0 LMH/psig
Normalized Water Permeability =
11.0 LMH/psig x TCF 20 °C where TCF 20 °C = 1.109
(Correcting water permeability for temperature;
from 16 °C to 20 °C)
Temperature correction factor from Table 3 for 16 °C =
1.109
Normalized Water Permeability =
11.0 x 1.109 = 12.2 LMH/psig
