Product description
Depth filter modules are lenticular filtration units designed for closed-system liquid filtration in industrial processing environments. The modules integrate multiple depth filter sheets into a compact stacked configuration, providing high filtration surface area within a single disposable module. These filtration modules enable efficient clarification, polishing, and particle reduction of liquids while minimizing handling compared with traditional plate-and-frame sheet filtration.Technical overview
Lenticular filter modules contain multiple circular depth filter sheets stacked between polypropylene support plates. Liquid flows through the filter layers from the outside toward the internal core, where clarified liquid exits through a central outlet. The integrated design allows depth filtration to be performed in a sealed housing, reducing contamination risk, minimizing air contact, and eliminating sheet handling associated with traditional filter presses.Operating principle
During filtration, liquid enters the module housing and flows through the stacked lenticular filter sheets. Suspended particles are retained within the porous depth structure of the filtration media. Retention occurs through several mechanisms:- Mechanical particle interception within the fiber matrix
- Depth entrapment within internal filtration channels
- Adsorptive interactions on the filtration media surfaces
Material options
Typical construction materials include:- Depth filter sheet media (cellulose-based filtration matrix with filtration aids)
- Polypropylene structural components
- Elastomeric seals
- Silicone
- EPDM
- Viton
