Overview: The Standard in Depth Filtration
ErtelAlsop Pak® Lenticular Filters represent a premier solution for high-efficiency depth filtration. Designed to bridge the gap between initial clarification and final sterile filtration, these modules offer a scalable, sealed, and easy-to-use alternative to traditional plate and frame filter presses.
For industries ranging from pharmaceuticals and cosmetics to food and beverage processing, the ErtelAlsop Pak® serves as a critical component in managing suspended solids, haze, and particulate retention. As a distributor for top-tier filtration technologies, Purecowater provides these versatile modules to tackle complex liquid filtration challenges.
How It Works: The Lenticular Advantage
The lenticular design, originally invented by Alsop Engineering, consists of a stack of individual filter cells. Each cell is comprised of a pair of depth filter sheets (such as MicroMedia® or AlphaMedia®) sealed at the edges. This construction resembles a stack of double convex lenses.
Key Advantages over Plate & Frame Filters
- Totally Enclosed System: Unlike open plate presses, lenticular housings are sealed, preventing leakage and minimizing valuable product loss.
- Rapid Change-out: Modules can be replaced in minutes rather than hours, significantly reducing downtime.
- Scalability: Available in 12-inch and 16-inch diameters with varying cell counts (up to 18 cells), allowing for precise sizing based on flow rate and solids loading.

Media Configurations and Options
One of the strongest features of the ErtelAlsop Pak® line is the variety of media available. Purecowater can assist in selecting the correct media formulation for your specific stream.
| Media Type | Composition | Primary Applications |
|---|---|---|
| Zeta-Pak® (MicroMedia®) | Cellulose + Diatomaceous Earth (DE) / Perlite | General purpose workhorse. High solids loading and retention of ultra-fine particles via Zeta potential. Ideal for beverages and botanical extracts. |
| Disc-Pak® (AlphaMedia®) | 100% Cellulose | Used where mineral filter aids (DE) are not permitted. Excellent for dielectric oils, lubricating oils, syrups, and cosmetic perfumes. |
| Bio-Pak® | Pharmaceutical Grade Media | Strict extractable limits for pharmaceutical and biological applications. |
| MicroClear® | Immobilized Activated Carbon | Color correction, odor removal, and impurity adsorption without the mess of bulk carbon. |
The Zeta-Pak® is particularly effective in botanical extract filtration due to its high flow rate and efficient wax/lipid removal [clearsolutionscorp.com].

Key Applications
Due to the wide range of media grades (MicroMedia, AlphaMedia, etc.), these filters are deployed across diverse sectors:
- Life Sciences: Buffer filtration, cell harvesting, and API purification.
- Food & Beverage: Polishing distilled spirits, haze removal in syrups, and clarification of wines.
- Deep-bed Filtration: Effective retention of high solid loads that would clog standard pleated cartridges instantly.
- Utilities & Industrial: Filtration of dielectric oils for transformers and general chemical processing [clearsolutionscorp.com].
