Fabricating novel PVDF-g-IBMA copolymer hydrophilic ultrafiltration membrane for treating papermaking wastewater with good antifouling property

open access: yesWater Science and Technology, 2021
Ultrafiltration membranes are widely used for the treatment of papermaking wastewater. The antifouling performance of polyvinylidene fluoride (PVDF) ultrafiltration membranes can be improved by changing the hydrophilicity.

Influence of Ozone Treatment on Ultrafiltration Performance and Nutrient Flow in a Membrane Based Nutrient Recovery Process from Anaerobic Digestate

open access: yesMembranes, 2020
Membrane filtration of biological suspensions is frequently limited by fouling. This mechanism is well understood for ultrafiltration of activated sludge in membrane bioreactors.

ULTRAFILTRATION [PDF]

open access: yesJournal of Biological Chemistry, 1931
Assuming that "bound" water loses its solvent properties, it is shown by an ultrafiltration method that in solutions of gelatin, casein, starch, and glycogen, and in blood serum, only a very small fraction of the water can be associated with the colloids in this form.

Research on the current situation of ultrafiltration combined process in treatment of micro-polluted surface water [PDF]

open access: yesE3S Web of Conferences, 2020
At present, most of the source water of domestic urban water supply treatment plants is taken from micro-polluted surface water. With the further improvement of drinking water sanitation standards, the traditional “coagulation-sedimentation-filtration ...

Ultrafiltration in Acute Heart Failure [PDF]

open access: yes, 2019
Congestion is the predominant cause of more than 1 million annual heart failure hospitalisations and recurrent fluid overload predicts poor outcomes. Unresolved congestion trumps serum creatinine increases in predicting adverse heart failure outcomes. No

Effect of hydrophilic / hydrophobic fractions of Natural Organic Matter on irreversible fouling of membranes [PDF]

open access: yes, 2009
Natural organic matter (NOM) has been identified as a major factor affecting membrane processes performances, but its impact is difficult to quantify from global parameters such as organic carbon content.
