Benefits of our conceptOur concept ´Cross-flow for Wine´ is a result of international collaboration of specialized companies from the Czech Republic, the Netherlands, Italy and Germany. Its main benefits are:

Adsorption of polysaccharide, polyphenol and Tannin

Advantages of the system with reverse flow:• Highercleaningefficiency• Increasedfiltrationflow• Greatercapacityofthefiltrationcycle

Advantages of PP membrane in comparison with PES:• Loweradsorptiontendencyofwineingredients–gentlerfiltration• Symmetricalpores–highercleaningefficiency• Greaterresistancetoproteinsandabrasion• Longermembranelifespan• 100%alcoholresistance
