La filtration membranaire est un proc\u00e9d\u00e9 de s\u00e9paration physique fonctionnant gr\u00e2ce \u00e0 la combinaison de gradients de pression et de diff\u00e9rentes vari\u00e9t\u00e9s de membranes. Ce proc\u00e9d\u00e9 permet de s\u00e9parer les mol\u00e9cules contenues dans des solutions liquides en fonction de leur taille. Il existe quatre types de membranes dont la taille des pores va en ordre d\u00e9croissant : microfiltration (MF), ultrafiltration (UF), nanofiltration (NF) et osmose inverse (OI). Plus les membranes ont des pores de petits diam\u00e8tres, plus la pression requise pour la r\u00e9aliser la filtration est \u00e9lev\u00e9e.
\nL\u2019osmose directe est un proc\u00e9d\u00e9 membranaire qui permet la concentration de liquides gr\u00e2ce \u00e0 l\u2019utilisation d\u2019une membrane s\u00e9lective et d\u2019une solution de soutirage riche en sel, en sucre ou autre solut\u00e9. Le r\u00f4le de la solution de soutirage consiste \u00e0 attirer l\u2019eau du liquide que l\u2019on cherche \u00e0 concentrer gr\u00e2ce au ph\u00e9nom\u00e8ne d\u2019osmose. Ce type de filtration ne requiert pas l\u2019utilisation de pressions \u00e9lev\u00e9es et peut m\u00eame \u00eatre utilis\u00e9 \u00e0 temp\u00e9rature ambiante, ce qui est utile pour pr\u00e9server les mol\u00e9cules fragiles. L\u2019osmose directe permet d\u2019atteindre un niveau de concentration de 60-65% de solides totaux.<\/p>\n<\/div>\n
