Gas‐liquid displacement method for estimating membrane pore‐size distributions

A method to characterize the compressibility and stability of microfiltration membrane

“…1), scanning electron microscope (Hitachi Ltd., SU-70), ultrapure water manufacturing system (Chengdu Ultrapure Technology Co., Ltd., China, UPH-1-5T), and a pore size distribution measurer (self-made according to gas-liquid displacement method) [22].…”

Algae-dewatering using rotary drum vacuum filters: Process modeling, simulation and techno-economics

“…Therefore, the minimum pressure required for displacing the water out of the algal cake-layer can be determined by Eq. (23) [12,33],…”

“…In the algae dewatering zone, the air flow passing through the cake-layer will also be excavated with the vacuum pump. Evaluation of energy consumption of the vacuum pump needs to estimate this air flow-rate, which is determined by the Hagen-Poiseuille equation [12,29,34] as shown in Eq. (28),…”

“…A low pressure (e.g. 20-30 kPa) can generate a high flux through these well-tuned and highly porous filter media [12].…”

Micro- and nano-characterization of membrane materials

“…Holt et al (2006) predicted the high water flux with molecular dynamics simulations, which attributed the observed high water flow rates to the formation of water ''wires'' in the confined space inside the nanotube. Shao et al (2004) also introduced a universal mathematical model and an approximate model for Fig. 6.…”
