Modern crossflow-technology now allows us to dose bentonite and activated carbon upstream of the hollow fiber membranes resulting in single step stabilization and clarification. It enables wineries to reduce bentonite/activated carbon consumption, eliminate settling time after fining, reduce wine waste and lees volumes, all while saving energy and water consumption. The application takes place via an inline dosing system, which is connected to a flowmeter. We highly recommend you to contact the system manufacturer before attempting a trial.

Blancobent UF and Acticol FA UF products are unique due to their defined particle size
Bentonite and activated carbon suitable for crossflow filtration have a defined particle size distribution and are therefore characterized by lower abrasiveness towards membrane systems. For example the bentonite particles in Blancobent UF are below 100 microns and just 0.2% are greater than 45 microns. (table 1)
Blancobent UF
This highly specialized bentonite is used to drastically reduce the time and effort required for protein stabilisation and filtration. It is applied pre-quelled to the crossflow system without any prior tapping or pre-filtration. The purity and high adsorption capacity of Blancobent UF additionally reduce the dosage compared to conventional bentonites by up to 30%.
Acticol FA-UF
Acid activated, highly efficient powdered carbon of pure plant origin. Due to the high phenol adsorption of Akticol FA-UF, lower doses are possible while at the same time a high decolorizing effect can be obtained. Composition and purity of this carbon make application in combination with cross-flow filtration systems very gentle with the lowest possible abrasive wear.

By combining several process steps, bottling schedules can be decisively simplified and made more flexible. The time necessary for preparation and cleaning is drastically reduced. The existing tank space is utilized in the best possible way, which increases the profitability of the winery. The CO2 footprint of the wines is reduced, water consumption is consistently minimized as well. Wines can thus be brought to market with pinpoint accuracy and sustainability.
- Reduction of time and labor
- Savings in energy and water
- Production capacities are increased and flexiblized
- Less bentonite required compared to conventional bentonites
- Extremely fine grain size prevents damage to filter membranes
- No filter aids necessary = no waste disposal
