Seitz® Depth Filtration Products

Sheet based filtration products are typically used for polishing filtration in winemaking. These products are comprised of a mixture of materials including cellulose, diatomaceous earth and perlite that provide an excellent combination of adsorption, surface and depth filtration.

Key attributes of a good polishing filter are:

Removal of undesirable colloids which are strongly linked to membrane fouling.

Microbial reduction, to reduce the load on pre and final filters at bottling

Maintains organoleptic properties

High yield

High flow rate

While effective, flat filter sheets do have disadvantages. Filter sheets configured in a plate and frame unit are an open system. This potentially exposes the wine to risk of contamination from the outside environment.

With multiple sheets assembled in parallel, installation and assembly is labor intensive.

Additionally, with sealing dependent on the operator and equipment maintenance, edge leakage is common and results in product loss and unsanitary conditions.

Pall has responded to these drawbacks, by introducing unique technologies in enclosed housings to improve performance in polishing wine.

SUPRApak™ depth filter modules, the newest development in sheet filtration technology are designed to give winemakers a superior option for reducing costs and improving yields. Especially useful for high volume wine production, one SUPRApak housing can replace up to 150 60cm x 60cm sheets.

SUPRAdisc™  ll depth filter modules are a design optimization of the traditional "Single Cell" lenticular modules which launched to the market in the 1980s. With the unique capability to be cleaned and back-flushed, these modules meet the needs of the small to medium winery perfectly.

Seitz™ZD media. Both of the aforementioned technologies are now also available in our new Zero DE (ZD) format which allows the user to remove diatomaceous earth from their process.
