LENTICULAR FILTRATION ADVANTAGES



Scott Labs Split Dome Lenticular Housing

Lenticular filtration is an economical option for small to medium-sized producers because it provides up to 50% more throughput than sheet filtration, greatly reducing wine loss. The media can be backflushed, stored and reused multiple times, saving the winery time and money. Continue reading to learn all of the advantages of lenticular filtration. 

SETUP

Lenticular housings are quick and easy to setup and tear down. In the Drops of Knowledge video below, we outline the entire process of lenticular setup and usage.

REUSABLE MEDIA

Being able to easily store and reuse the media multiple times helps to offset the initial cost of the housing and media.

MEDIA REGENERATION

The filter modules can be backflushed and forward flushed to increase throughput by at least 50% in comparison to traditional filter sheets.

REDUCED DO & DRIP LOSS

Reduced dissolved oxygen (DO) levels and drip loss. When you purge with nitrogen properly, you only lose what is absorbed in the media. Keep in mind that there is a deceptively large amount of media in a small space in comparison to sheet filters. From a dissolved oxygen standpoint, these can be purged effectively with nitrogen before and after to essentially eliminate DO pickup in the filtered product, as well as hoses/pumps/tanks to and from the filtration. Drip pan monitoring is eliminated. Carbon dioxide tends to dissolve, so nitrogen is preferred.

SCALABILITY

For a low cost, you can build in some growth potential into the housing. For example, you could purchase a split dome 4-high housing, and a 1-high/2-high/3-high center post to use in accordance with batch size, building in growth and flexibility as needed. This would be comparable to buying a large sheet filter and using a blind plate and spindle extension in a plate and frame. Another advantage is that 12” modules also fit in a 16” housing.

FOOTPRINT

Lenticular housings take up a lot less space and are packed with a much larger amount of surface area. They can be put on casters or a skid for more mobility. Housings can be used in series loaded with different porosities for a single pass filtration.

MAINTENANCE & DESIGN

A lenticular housing is easier to keep clean. Maintenance is minimal and includes one larger base silicone or Viton gasket and occasionally, the plastic part of the hold-down device and 1.5” gaskets for the tri-clover fittings.

BOTTLING LINE COMPATABILITY

Lenticular housings and media are much more suitable for running in-line with bottling than sheet filters. The media and housing design is much better suited to efficiently handle the stops and starts on a bottling line. A 16” 4-high housing equipped with Seitz EK filter media is widely used on medium-sized bottling lines (up to 45 gpm) to correct filterability because of its efficiency and effectiveness.
