... and organic pollutants from contaminated water. In this study, rotating RO, which takes advantage of Taylor-Couette flow instabilities to reduce the flux decline related to concentration polarization and membrane fouling, was investigated experimentally and compared to a dynamic model based on RO

The potential of microfiltration and ultrafiltration process in purification of raw sugar beet juice
... turbidity and hardness in the rate of 49.12%, 78.26% and 6.65%, respectively. Keywords: Microfiltration; Ultrafiltration; Sugar beet raw juice; Flux; Purity; Turbidity; Color 1. Introduction In sugar industry, the main stage is the purification or separation of impurities and non-sugar compound ...

... quality was attained with more than 99% oil rejection being achieved. In some circumstances, oil contamination resulted in an increase in membrane flux and, as an example, at 50% oil contamination, an increase in membrane flux of 40% was observed. However, membrane permeate quality was deterioratin ...

... was principally affected by the temperature. The highest retention was observed at 20°C. Increase of both pressure and temperature increased the flux, but the impact of pressure was higher than that of temperature. The highest flux was measured at 40°C. There was no appreciable difference betwee ...

Treatment of waste water from metal working by ultrafiltration, considering the effects of operating conditions
... feed and permeate were collected in order to measure the retention of oil, the zeta potential, and the oil drop size. The obtained results showed a flux increase with increasing pH. The highest flux was achieved at alkaline conditions but the highest retention was observed when the pH was acidi ...

... of approx. 90% and were capable of reducing initial concentrations of 15mg/L to below the New Zealand regulatory limit of 1.17 mg/L. The permeate flux at a transmembrane pressure of 2.1 bar was approx. 20 l/m2/h (LMH) and 40 LMH, respectively through the membranes with MWCO 3 kDa and 5 kDa. Thes ...

Separation of ultrafine TiO2 from aqueous suspension and its reuse using cross-flow ultrafiltration (CFU)
... such as feed concentration, transmembrane pressure, cross-flow velocity, pH, electrolyte and membrane molecular weight cut-off (MWCO) on the flux were investigated. Thereafter, the activity of reused photocatalyst for dye wastewater by CFU and coagulation processes was compared respectively.

... potential to improve many aspects of membrane performance. This study investigates the influence of chemical pre-treatment and wetting on membrane flux and retention. The results show that chemical pre-treatment, with either a phosphate buffer or alkaline cleaning agents, enhances the flux an ...
