Five new mathematical triple fouling models were developed to explore the flux decline behavior during the microfiltration. The first model was developed by the assumption of the successive effects of standard mechanism, intermediate pore blockage and cake formation by using the standard blocking flux expression in the model calculations. The second and third models also obtained by the success...

one of the barriers during whey filtration using uf membrane is the fouling phenomenon of the membrane, which is caused by whey proteins. in this work, the uf membranes were prepared using polysufone (psf), dimethyl formamide (dmf), 1 wt.% poly vinyl pyrrolidone (pvp) and different concentrations of licl via phase inversion induced by immersion precipitation. the prepared membranes were charact...

An apparatus that integrates solid-state nanopore ionic current measurement with a scanning-probe microscope is developed. When a micrometer-scale scanning-probe tip is near a voltage-biased nanometer-scale pore (10–100 nm), the tip partially blocks the flow of ions to the pore and increases the pore access resistance. The apparatus records the current blockage caused by the probe tip and the l...

Piezo proteins have been proposed as the long-sought-after mechanosensitive cation channels in mammals that play critical roles in various mechanotransduction processes. However, the molecular bases that underlie their ion permeation and mechanotransduction have remained functionally undefined. Here we report our finding of the miniature pore-forming module of Piezo1 that resembles the pore arc...

One of the barriers during whey filtration using UF membrane is the fouling phenomenon of the membrane, which is caused by whey proteins. In this work, the UF membranes were prepared using polysufone (PSf), dimethyl formamide (DMF), 1 wt.% poly vinyl pyrrolidone (PVP) and different concentrations of LiCl via phase inversion induced by immersion precipitation. The prepared membranes were charact...

INTRODUCTION Clogging of the pore-space is the primary cause of efficiency reduction and aging of wastewater treatment devices such as sand filters and subsurface flow constructed wetlands (US EPA 2000; Langergraber et al., 2003; Kadlec and Wallace, 2009). Significant efforts have been undertaken to study and understand the mechanisms leading to clogging and to design solutions to alleviate its...
