Filtration

The quality of a wine depends on many factors. Among all of them, filtration is essential to achieve a great wine in which cleanliness and the absence of microorganisms guarantee stability in the bottle. The choice of a type of filtration according to the character of the wine will mean success in this process, which is why at AGROVIN we work with the best filter media and the experience of EATON, a leading company in the filtration area.

Soil filtration

Pearls

They result from the processing of a volcanic rock whose chemical composition consists mainly of silicon dioxide (SiO₂) and aluminum oxide (Al2O₃), in addition to other compounds. Perlites have water occluded in combination, which gives them the exceptional property of expanding when subjected to high temperatures. The expanded perlite, after delicate processes of crushing and classification, is transformed into a filtering aid whose particles, intertwined, can form an incompressible cake, with 80 – 90 % of hollow spaces, through which the liquids to be filtered will pass, retaining the solid elements in suspension, even those of microscopic size.

Diatomaceus

They come from very porous sedimentary rocks, consisting essentially of fossil siliceous shells of microoscopic unicellular algae and are used as filtering aids, due to their porosity and high adsorption capacity. Because of its high porosity, the diatomite extracted from the quarries contains between 60 and 70% water. After grinding, the mineral is dried, crushed and then purified to powder form. The Radifil diatomaceous earth is then calcined in furnaces at 800 to 1100 ºC. This calcination removes organic matter and agglomerates the diatoms, without altering their porosity. After cooling, the product is ground and then sorted in order to make precise granulometric cuts, responding to the various applications.

Becopad filter plates and modules

100% cellulose, 100% quality

BECOPAD depth filtration media allow, thanks to their innovative technology, to combine the strictest microbiological safety standards with respect for the organoleptic qualities of the wines.

Reasons to use Becopad

Maximum respect for the organoleptic profile by eliminating the so-called "papery odor" of the plates.
20% more efficiency.
50% less rinse water.
Possible counter-current regeneration, being able to recover a high percentage of its filtration capacity.
99% less dripping.
Wet breakage resistance.
High microbiological retention even at high porosities.
Preserves Colloids, Colors and Aromas.
Natural, ecological and 100% biodegradable (only filtering plates).

Beco filter cartridges

BECO filter cartridges offer various solutions for the food and beverage industry ranging from depth filtration cartridges (BECO PROTECT) to the reduction and retention of microorganisms with membrane filter cartridges (BECO MEMBRAN).

BECO PROTECT FS

The quality of a wine depends on many factors. Among all of them, filtration is essential to achieve a great wine in which cleanliness and the absence of microorganisms guarantee stability in the bottle. The choice of a type of filtration according to the character of the wine will mean success in this process, which is why in AGROVIN we work with the best filter media and the experience of EATON, a leading company in the filtration area. In this way, we not only provide you with quality products, but also with their experience and advice in the whole wine filtration process.

BECO PROTECT FS is made entirely of polypropylene, achieving maximum protection of the organoleptic qualities of the wine, as no adsorption occurs, allowing pigments and aromas to remain in the wine.

BECO PROTECT PP Pure

BECO PROTECT PP Pure depth filter cartridges are designed for pre-filtration and fine filtration of wine. This cartridge, thanks to the pleated polypropylene filtering material, offers a very high flow rate.

All the materials used in its manufacture guarantee a neutral filtration for the product, without adsorption or migration of particles.

BECO MEMBRAN PS PLUS

To ensure the stability of the finished product, the use of a membrane filter cartridge that guarantees integrity with reliable microbiological retention is essential. Other important characteristics are a low impact on the organoleptic quality of the product in aspects such as aroma, appearance and taste of the wine, a constant flow rate, a long service life and easy regeneration.

The BECO MEMBRAN PS Plus membrane filter cartridge helps to meet the most stringent microbiological stabilization requirements and is capable of performing the tasks necessary to achieve the highest levels of wine quality.

BECO MEMBRAN PS Plus filter cartridges are specially designed to meet microbiological safety and long durability in final filtration. BECO MEMBRAN PS Plus filter cartridges are manufactured with high quality polyethersulfone membranes. The membranes are protected by polyester support fleece and have a broad chemical compatibility. An inner and outer polypropylene support cartridge ensures maximum mechanical stability. Nylon end caps allow easy wetting of the membrane filter cartridges for integrity testing.

Wine filtration is a complex process in which several factors and multiple variables come into play. In order to achieve an optimal filtration it is essential to have sufficient knowledge and the right advice. From AGROVIN we offer you all our experience to help you in all the stages of filtration. In addition, we know the chemical compatibilities of our membranes and we can advise you on their cleaning and regeneration protocols.
