Introduction to Lenticular Depth Filtration
Industrial liquid filtration requires robust, scalable, and efficient solutions. At the forefront of this technology are ErtelAlsop Pak® Lenticular Filters. Designed for high-performance applications ranging from botanical extraction to pharmaceutical processing, these depth filter modules offer a superior alternative to traditional plate and frame filters. As a distributor for top-tier filtration manufacturers, Purecowater is proud to offer these advanced filtration solutions to our clients.
The Pak® Lenticular Filter is a modular depth filter cartridge that combines the benefits of depth filtration media with the convenience of a compact, enclosed housing. Whether you are dealing with haze removal in distilled spirits or ultra-fine particle retention in chemical processing, the Pak® series is engineered to deliver consistent results.
What Are ErtelAlsop Pak® Cartridges?
ErtelAlsop Pak® cartridges (often referred to as lenticular modules) are assembled using a stacked design of lenticular cells. Each module consists of multiple double-convex filter cells stacked vertically. This design maximizes surface area within a small footprint, allowing for high flow rates and significant solids-loading capacity.
According to ertelalsop.com, these modules come in standard diameters of 12-inch (30.5 cm) and 16-inch (40.6 cm), typically containing between 5 to 18 stacked cells per cartridge. The edge of each media pair is sealed using a patented polypropylene process to prevent bypass and ensure integrity.
Key Features
- Scalability: Available in various lengths and cell counts to fit different housing sizes.
- Diverse Media Options: Compatible with Micro-Media®, AlphaMedia®, and MicroClear® depth filter sheets.
- Zeta Potential: Many options, such as the Zeta-Pak®, utilize electrokinetic adsorption (zeta potential) to remove sub-micron particles effectively.
Technical Specifications
Understanding the technical capabilities of these filters is crucial for selecting the right module for your process. The Pak® filters are renowned for their versatility in micron ratings and connection types.
| Specification | Details |
|---|---|
| Micron Ratings | 0.25 µm to 15 µm (Nominal) including 1.0, 2.5, and 5.0 micron options. |
| Diameters | 12-inch and 16-inch |
| End Configurations | Double O-Ring, Flat Gasket |
| Core Material | Polypropylene |
| Filter Media | Cellulose, Diatomaceous Earth (DE), Perlite, or Carbon |
| Gasket Material | EPDM, Silicone, Buna-N, Viton, etc. |
As noted by clearsolutionscorp.com, the polypropylene supports and EPDM gaskets make these filters compatible with numerous solvent types, which is particularly beneficial for extraction processes.
Working Principle: The Micro-Media Advantage
The core technology behind the efficacy of ErtelAlsop Pak modules is the media itself. The Zeta-Pak® series, for instance, is the workhorse of the line. It uses cellulose fibers impregnated with Diatomaceous Earth (DE) filter aid.
Why Diatomaceous Earth?
The integration of DE forms a rigid, porous structure (cake) that acts as a sieve. It provides:
- High Flow Rates: The large surface area allows liquids to pass through quickly without sacrificing retention.
- Tortuous Path Filtration: Particles get trapped within the complex matrix of fibers and DE, not just on the surface.
- Waxes and Lipid Removal: Especially in botanical extracts, the DE helps efficiently shear waxes and lipids from the fluid stream (clearsolutionscorp.com).
Applications and Industries
ErtelAlsop Pak Lenticular Filters are versatile enough to be used across a broad spectrum of industries. Their enclosed design ensures a sanitary process, making them ideal for:
- Botanical Extracts: Removal of biomass, waxes, and lipids in solvent-based extractions.
- Food & Beverage: Polishing filtration for syrups, juices, and edible oils.
- Distilled Spirits: Chill haze removal and particulate reduction without affecting flavor profiles.
- Life Sciences & Pharmaceuticals: clarifying cell cultures and active pharmaceutical ingredients (APIs).
- Chemical Processing: Catalyst recovery and solvent purification.
