The preparation and characterization of alumina membranes with ultra-fine pores : Part 4. Ultrafiltration and hyperfiltration experiments [PDF]

open access: yes, 1985
The rejection characteristics of three types of alumina membranes for polyethylene glycol (PEG) polymers and dextrans soluted in water have been investigated. If the temperature at which the membranes are treated is increased, the pore size increases and

Effect of pH of Coagulant on the Treatment of Wastewater from Tofu Industry

open access: yesE3S Web of Conferences, 2018
Wastewater generated from the tofu industry usually still contains high organic pollutants that can contaminate the surface water. Therefore, it should be treated properly before it can be disposed to the environment.

Novel use of an ultrafiltration device as an alternative method for fluid removal in critically ill pediatric patients with cardiac disease: a case series

open access: yesPediatric Reports, 2016
Fluid overload (FO) is a common complication for pediatric patients in the intensive care unit. When conventional therapy fails, hemodialysis or peritoneal dialysis is classically used for fluid removal.

Study on fouling behaviour of ultrafiltration and nanofiltration during purification of different organic matter polluted wastewaters [PDF]

open access: yes, 2017
The boundary flux concept is a profitable tool to analyse fouling issues in membrane processes. The boundary flux value separates an operating region characterized by reversible fouling formation from irreversible one.

Influence of Type of Substrate and Enzyme Concentration on Formation of Galacto-oligosaccharides

open access: yesCzech Journal of Food Sciences, 2009
Different substrates and different concentrations of enzyme (Maxilact LX 5000) for galacto-oligosaccharides synthesis were tested. Lactose in phosphate buffer (138 mmol/l), ultrafiltration permeate (115 mmol/l), recombined whey (136 mmol/l) were used as ...

Mass transfer in corrugated-plate membrane modules. II. Ultrafiltration experiments [PDF]

open access: yes, 1989
The application of corrugations as turbulence promoters in membrane filtration was studied. In ultrafiltration experiments with polysulfone membranes using Dextran T70 as solute, it was found that the corrugations result in reduced energy consumption or ...

Diffusion and permeation in binary solutions: Application to\ud protein ultrafiltration [PDF]

open access: yes, 2009
During the ultrafiltration of colloidal solutions the particles can form a porous medium (filter cake) or a diffuse boundary layer (concentration polarization) above the semipermeable membrane depending on the magnitude of the filtration pressure.
