Advantages of Lenticular Filtration

Last updated: 6/2021

Applies to: Beverage producers considering lenticular filtration. Whether you’re making the switch from filter sheets or are starting out with lenticular, evaluate the main benefits here.

Lenticular filtration is a popular alternative to sheet filtration that uses similar media for similar applications but boasts many advantages. Like sheet filtration it uses nominally rated  filter media  with a range of porosities and can be used at a variety of points in the filtration/stabilization process. However, instead of sheets, lenticular filtration uses modules that stack inside a contained housing. The housing and media design give lenticular filtration several advantages over sheet filtration, and in general makes it an excellent choice of filtration system:

Easy to use and maintain

Lenticular filters are very easy to set up and tear down. They are also easy to keep clean. Maintenance is minimal with only three main pieces that need to be replaced: one base silicone or Viton gasket, 1.5” gaskets for the tri-clover fittings, and occasionally, the plastic part of the hold down device.

Footprint

Lenticular housings take up much less space while housing a much larger amount of filtration surface area. They can also be put on casters or a skid for more mobility.

Reusable & Regenerable Media

Storing media between use and using it multiple times helps to offset the initial cost of the media. The modules can be backflushed and forward flushed to increase throughput by at least 50% in comparison to sheets.

Minimal drip loss and low Dissolved Oxygen

With lenticular filtration, there is a deceptively large amount of media in a small space in comparison to sheet filters. Additionally, it is all self-contained and does not use a drip pan like sheet filters. This lends itself to lower drip loss, but also protects against dissolved oxygen (DO) pickup. From a dissolved oxygen standpoint, the housing and module can be purged effectively with nitrogen before and after filtration to essentially eliminate DO pickup in the filtered product. Additionally, when purged properly with nitrogen properly, lenticular filters only lose wine that is absorbed in the media.

Scalability

Lenticular filtration leaves room for potential growth in production or an increase in throughput needs. The size of lenticular housings are classified by:

  • diameter (12 or 16 inches)
  • height in terms of modules (1,2,3 or 4)

The larger diameter and larger height modules are the most flexible: 16” housings can use both 12” and 16” media, and taller housings can use any number of modules by simply changing out the center post. For example: If batch sizes are projected to start small but you’d like to leave room for growth in production, you may consider a 16” 4-high housing for the most flexibility.

Bottling line compatibility

Lenticular housings and media are much more suitable for running in-line with bottling than sheet filters. The media and housing design makes them much better suited to efficiently handle bottling line start/stops. A 16” 4-high housing loaded with Seitz EK media is widely used on medium sized bottling lines (up to 45 gpm). For larger speed bottling lines, a Suprapak 6-high setup can comfortably handle 110+ gpm flow rates in-line with bottling, making it one of the most efficient choices on the market.
