Lenticular Filtration

Lenticular filtration

Lenticular filtration is an enclosed form of depth filtration used to clarify liquids and remove suspended solids. It is commonly chosen when you need reliable clarity, hygienic handling, and predictable filtration in a closed system.

What is a lenticular filter used for?

You use a lenticular filter to reduce haze and turbidity, capture fine particles, and improve visual clarity before a final cartridge filter, bottling, or downstream processing. Typical applications include:

• Beer, wine, cider, spirits, juice, and other beverages
• Sugar solutions, flavors, and other liquid foods
• Chemicals and process liquids that require clarification
• Cosmetics and personal care liquids
• Pharmaceutical and biotech process streams where hygiene and closed handling matter

What does the filter do?

A lenticular system uses stacked, disc-shaped filter modules installed inside a sealed housing. The filter media works as a depth matrix. Particles get retained throughout the thickness of the media, not only on the surface. This gives high dirt-holding capacity and stable clarification over longer runs.

Many lenticular depth media are based on cellulose combined with mineral filter aids such as diatomaceous earth and or perlite, depending on the grade and manufacturer. This composition supports clarification and helps capture a wide range of particle sizes. You can select grades for coarse clarification, fine clarification, polishing, or microbial reduction, depending on your process target.

Why choose lenticular filtration?

• Closed and hygienic filtration that reduces operator exposure and contamination risk
• Easier handling than traditional sheet filtration, with cleaner change-outs
• Lower product loss due to enclosed operation and compact module design
• Flexible performance, you can scale capacity by adding modules and choose media grades for your clarity goal
