Experimental Analysis of Structural Change and Rheological Behavior of Macromolecular Solutions with Guar and Xanthan Gums in Crossflow Microfiltration Processing
The present paper reports on the structural change and rheological behavior of mixtures of macromolecular suspensions (guar and xanthan gums) in crossflow microfiltration processing. Mixtures in suspension of guar and ...
Effect of enzymatic treatment on the cross-flow microfiltration of acai pulp: Analysis of the fouling and recovery of phytochemicals
(ELSEVIER SCI LTDOXFORD, 2012)
This study aimed to investigate the effects of pectinase enzyme treatment of acai pulp on cross-flow microfiltration (CFMF) performance and on phytochemical and functional characteristics of their compounds. Analyses of ...
Clarification of purple cactus pear juice using microfiltration membranes to obtain a solution of betalain pigments
(Instituto de Tecnologia de Alimentos - ITAL, 2015)
Betalains are fruit pigments possessing health-giving properties. To isolate the pigments, the juice must be separated from the fruit matrix, which contains biopolymers. The aim of this study was to clarify cactus pear ...
Manufacture of ceramic membranes for application in demulsification process for cross-flow microfiltration
(ELSEVIER SCIENCE BV, 2009)
This paper describes the manufacture of tubular ceramic membranes and the study of their performance in the demulsification of soybean oil/water emulsions. The membranes were made by iso-static pressing method and micro ...
Microfiltration of umbu (Spondias tuberosa Arr. Cam.) juice
(Elsevier Science BvAmsterdamHolanda, 2007)
Composite ceramic membranes from natural aluminosilicates for microfiltration applications
This work concerns to the development and characterisation of support, active layer and tubular composite membranes (CM) from natural aluminosilicates as principal components (clay, bentonite, feldspar, quartz, alumina). ...
Efeito do tratamento enzimatico, da velocidade tangencial e da pressão transmembrana na microfiltração da polpa diluida de umbu (Spondias tuberosa Arr. Cam.)Effect of the enzymatic treatment, the crossflow velocity and the transmembrane pressure during the microfiltration of umbu (Spondias tuberosa Arr. Cam. ) diluted pul
Demulsification of water/sunflower oil emulsions by a tangential filtration process using chemically impregnated ceramic tubes
(Elsevier B.V., 2007-02-15)
A tangential filtration process was implemented in this study using porous ceramic tubes made of alpha-alumina produced by the slip-casting technique. These tubes were sintered at 1450 degrees C and characterized by mercury ...
Dynamics of a continuous flash fermentation for butanol production
The ABE (acetone, butanol, ethanol) fermentation is characterized by its low productivity. In this paper, this issue is overcome with an innovative industrial process that employs the flash fermentation technology. The ...
