Removal of vegetable tannins to recover water in the leather industry by ultrafiltration polymeric membranes
(Institution of Chemical Engineers, 2015-01)
The leather tanning industry consumes large amounts of water and produces, consequently, significant volumes of wastewater with high concentration of chemicals and organic matter. One of the main chemicals present in ...
Application of a composite ultrafiltration membrane for biodiesel purification
(Universidade Federal do Rio de Janeiro, 2018-03)
This study was carried out to investigate the potentialities of the application of membrane technology in biodiesel purification without need of the decantation step. A new composite UF membrane was prepared from poly(vinylidene ...
Synthesis Polysulfone-Acetylethanol Ultrafiltration Membranes. Application to Oily Wastewater Treatment
(Science and Education Publishing, 2013-09)
Chemical functionalization of polymers after the synthesis of membranes has great importance for various applications separative processes of industrial or environmental interest. Polysulfone (PSf) is one of the most applied ...
Plasma deposition of silver nanoparticles on ultrafiltration membranes: antibacterial and antibiofouling properties
(Inst Chemical Engineers, 2015-02)
tA novel and versatile plasma reactor was used to modify polyethersulphone commercial membranes. The equipmentwas applied to: (i) functionalize the membranes with low-temperature plasmas, (ii) deposit a film of ...
