mean high water
1.Using the high resolution spectrum database software USF HITRAN PC version 2.50, the mean transmittance of water vapor in wavelength interval 0.1 μm from infrared 1 to 14 μm along ground level horizontal path under STP condition is calculated, and the corresponding tables of mean transmittance are also given.
2.At 0.1MPa, pure water flux of the prepared PPENK UF membranes was from 129 L.m-2.h-1 ~ 1083 L.m-2.h-1, rejection to clayton-yellow was from 24%~99%, mean pore size was from 33nm to 96nm. Defect-free PPENK UF membranes with high performance can be prepared with proper evaporation time/temperature (240~330s, 80~100℃) process.
