Advanced Depth Filtration with ErtelAlsop Pak® Cartridges
For industries requiring high-purity liquid filtration without the mess and maintenance of traditional methods, the ErtelAlsop Pak® Lenticular Filter represents a significant upgrade. As a distributor for top-tier filtration solutions, Purecowater provides these advanced depth filter modules to tackle complex solid and liquid separation challenges.
The ErtelAlsop Pak®—often referred to as a lenticular cartridge—combines the proven efficiency of depth filter media with the convenience of a totally enclosed, modular design. Whether you are filtering botanical extracts, distilled spirits, pharmaceuticals, or industrial chemicals, the Pak® system offers scalability and reliability.
What is a Lenticular Filter?
The term “lenticular” refers to the shape of the filter cells, which resemble a stack of double convex lenses. A Pak® cartridge is assembled from multiple stacked filter cells (typically ranging from 5 to 18 cells per unit). Each cell consists of two sheets of depth filter media sealed at the edges.
This design allows for a large surface area to be packed into a compact footprint. Fluid flows from the outside of the cartridge, through the media, and into the center core, effectively trapping particulates within the tortuous path of the depth media.
Key Features and Benefits
- Totally Enclosed System: Unlike plate and frame filters which can leak and expose operators to fumes, lenticular housings are sealed. This ensures zero fluid loss and protects the product from external contamination.
- High Solids Loading: The complex matrix of fibers in the media provides high capacity for holding solids, meaning longer run times between change-outs.
- Scalability: Available in 12-inch and 16-inch diameters with varying cell counts, allowing users to scale up from pilot testing to full production easily.
- Rapid Change-Out: Replacing a Pak® cartridge takes a fraction of the time compared to restacking a filter press, significantly reducing downtime.
Media Formulations
ErtelAlsop offers distinct media grades to suit specific chemical compatibility and filtration goals. The success of the Pak® lies in selecting the right media formulation:
| Media Series | Composition | Primary Applications |
|---|---|---|
| AlphaMedia® | 100% Cellulose (No resins or inorganic aids) | Dielectric oils, perfumes, lubricating oils, and applications sensitive to silica/ions. |
| MicroMedia® | Cellulose + Diatomaceous Earth (DE) / Perlite + Wet Strength Resin | Haze removal, polishing, spirits, botanical extracts, and general clarification. High Zeta Potential. |
| MicroClear® | Immobilized Activated Carbon | Decolorization, odor removal, and removal of organic impurities. |
Technical Specifications
When specifying a lenticular filter for your process, consider the following technical parameters to ensure compatibility with your existing housings and process fluids.
| Micron Retention | Nominal ratings from 0.25 µm to 15 µm typically available (Common: 1.0, 2.5, 5.0 µm) |
| Diameters | 12-inch (30.5 cm) or 16-inch (40.6 cm) |
| End Cap Configurations | Flat Gasket or Double O-Ring (Code 222/226 style fitments) |
| Core Material | Polypropylene (standard), ensuring broad chemical resistance |
| Gasket Materials | EPDM, Buna-N, Viton, Silicone (Select based on solvent compatibility) |
| Maximum Temperature | Typically up to 180°F (82°C) depending on media and gasket selection |
Industrial Applications
The versatility of the ErtelAlsop Pak® makes it a staple in various high-demand sectors:
- Food & Beverage: Polishing syrups, clarifying distilled spirits, and haze removal in juices.
- Pharmaceuticals & Cosmetics: Filtration of active pharmaceutical ingredients (APIs), perfumes, and lotions.
- Botanical Extracts: Removal of waxes and lipids (winterization) using DE-impregnated media for high throughput.
- Utilities & Power Generation: Maintenance of insulating oils and transformer fluids.
