TLS filter

A technology specifically designed for the wine lees filtration or the filtration of products with a high percentage of suspended solids, as lees and musts, with the cross flow treatment that avoids the usage of filtration adjuvants.

TLS features

TLS Filter, cutting-edge technology

TLS Filter is VLS advanced solution for cross-flow filtration of products, such as lees and wine musts. The filter enables to free users from the daily use of rotary drum vacuum filters and offers an automatic, economical filtration without using earth: filtered wine is perfectly brilliant and clear (<1 NTU). It can directly be added into the filtered batch without undergoing any additional treatment (fining and filtration). The recovery, depending on the load of the filtered products, is higher than the one obtained with rotary drum vacuum filters. In addition, the filtered product is of better quality (analytic parameters are maintained, and wine is in a “pre-bottling” quality). Thanks to machinery remote control, the presence of the operator is minimal, thus ensuring easier and automatic operating process.

Membranes, filtration and advantages

This cross-flow filter specifically dedicated to the treatment of “tank bottoms” is equipped with a stainless steel membrane with a selectivity adapted to very clogging products such as fining lees (bentonite, …) and centrifuge sludge.
The membrane has the characteristics to be long lasting and resistant to pressure, temperature and chemical products. Those features are as many assets for the reliability of the filtration and the capacity of regeneration of the membranes.

“Tank bottoms” are filtered through a series of 2 to 12 membranes of 16 m² each. TLS filter exists with 2, 4, 6, 8, 10 and 12 membranes. Clogging is contained on the surface of the membrane which allows for more consistent removal of solids from filterable area, thus allowing for longer, more productive filter cycles. The filter, steam-sterisable, is more productive than a classical rotary drum vacuum filter, and will not lose quality or alcohol. Moreover, residues, still containing alcohol, can easily be valorized in a distillery.

Areas of application

  • Sweet lees from continuous or discontinuous flotation and static sedimentation
  • Post-fermentation lees and fermented lees post clarification
  • Wine and musts with high contents in solids
  • Spirits (Atex execution)
  • Fruit-juice concentrates and sugar solutions (sugar syrups, glucose, etc.)
  • Hard products with high concentrations of filtering aids (bentonite, gelatine and charcoal)


Cantina Montelliana is the most important wine-producing cooperative of the Montello and Colli Asolani area. Cantina Montelliana distinguishes itself for the mix between innovation and tradition in all the steps of the producing process, a frequent characteristic of wine-making establishments with a long history. Nowadays Cantina Montelliana uses our continuous floater and an isobaric cross-flow filter with 24 membranes for the filtration of sparkling wines.
