Filtration of wine
Main applications of cartridge membrane filtration in wine-making
? Defertilizing filtration of wines in cold sterile filling conditions
? Removal of residual opalescence in hot filling conditions
? Fine filtration of flushing water and washing liquors
? Sterilizing filtration of air and carbon dioxide, "breathing" of
tanks
Required conditions for faultless final membrane filtration
? Careful preliminary preparation of wine material
? Prefiltration of wine through a filter press incorporating a high-quality
cardboard
? Availability of sterile service media
? Carefully prepared deferilized vessels provided with filters for
sterile breathing
? Careful sterilization of equipment and all materials coming into
contact with wine
? Good sanitary state of the manufacturing plant
Membrane filtration is the most common technique used for
microbiological stabilization of beverages with no use of chemicals or heating.
In contrast to pasteurization, cold stabilization preserves aroma, taste and
the fine structure of wine.
EPM (ЭПМ) membrane filters ensure complete retention of
wine-spoiling microorganisms.
EPV (ЭПВ) fine filters displaying a high dirt-holding
capacity and a long service life ensure excellent protection of the membrane
element and extension of its service life.

Advantages for the user
|
|
The filter incorporates a reliable pleated
polyethersulfone membrane offering superior performance
|
? Broad chemical compatibility (pH 1 to 14)
? Excellent thermal stability (up to 100°C for water)
? Low binding capacity with respect to
albumens and proteins
? Extended service life resulting from
increased surface area (up to 0.75 m2/250 mm)
|
|
High retention efficiency with respect to
bacteria and microorganisms (99.98%)
|
? Available with pore sizes 0.65, 0.45 and
0.2 μm. Guaranteed removal of yeast cells, mold fungi
and bacteria before bottling
|
|
Pronounced asymmetric pore structure and
increased overall porosity of the membrane
|
? High filtration rate and low differential
pressures reduce financial costs
|
|
Stronger structure, longer service life
|
? Reliable preservation of filter integrity
in severe operating conditions
? The possibility of multiple sterilization
ensures cost-effective operation of the filter
|
|
100% control for guaranteed quality,
integrity testing
|
? Microbiological safety - penetration of
retained particles and microorganisms into the filtrate is ruled out
? Guaranteed integrity and effective operation
of the filter
? The filters can be subjected to a special
integrity test in the course of operation
|
|
Non-toxic, apyrogenic
|
? The filters have undergone extensive
testing and have been certified for use in food industry. The filters are
produced in accordance with a certified quality management system ISO
9001:2000

Effective
prefiltration
Most filling
lines use two-stage filtration of wines before filling.The
"prefilter-final filter" combination increases the reliability of the process,
ensure maximum filtration rate, a long service life and cost-effectiveness of
the filtration system. To
ensure high-quality prefiltration, Technofilter recommends pleated depth filter
cartridges EPV.S (ЭПВ.С) and, EPVg.P (ЭПВг.П) that can be repeatedly
reconditioned. Recommended
options for prefiltration before membrane filter elements
