Valorization of the filtration retentate : The main interest in using cross-flow filtration is to uphold suspended matters that will be separated and valorized in a distillery for example. On the contrary, when using traditional filtration, those suspended matters are absorbed and retained within the Kieselguhr used earth.

Operating safety : The filtration device as it is proposed is simple and fully automated for a perfect operating safety.You only need to plug, set the requested program and leave the filtration to be achieved … over night and day.

The winery staff can be working on some other tasks as only a monitoring of the process in action is necessary.

Respect of the environment and safety of operators : The use of a cross-flow filter, free from any used filtration earth, and therefore without any treatment, is respectful of the environment. There is no silica dust as in Kieselguhr earth, healthcare of operators is better taken into account.
