Advanced Depth Filtration with ErtelAlsop Pak® Lenticular Cartridges
For industries requiring high-purity liquid filtration with exceptional solids loading capacity, ErtelAlsop Pak® Lenticular Filters provide a robust and efficient solution. As a premier option for depth filtration, these modules combine the clarifying power of traditional plate and frame filter sheets with the convenience and safety of an enclosed cartridge system. Purecowater offers these advanced filtration solutions to help tackle complex solid and liquid separation challenges.
What Are Lenticular Filter Modules?
The ErtelAlsop Pak® cartridge (often referred to as a lenticular module) consists of depth filter media sheets stacked in a “lenticular” (lens-like) configuration. Each cell is comprised of two filter sheets sealed at the outer edge, creating a reliable barrier that traps particulates within the media matrix. This design maximizes surface area within a compact footprint, allowing for high throughput and superior particle retention.
Unlike surface filters that trap debris only on the outer layer, these depth filters utilize a complex matrix of fibers and filter aids (such as Diatomaceous Earth) to capture particles throughout the thickness of the media. This results in cleaner filtrate and longer service life.
Key Features and Benefits
Transitioning from open plate and frame presses to enclosed lenticular housings offers significant operational advantages. The Pak® design is engineered to streamline the filtration process:
- Totally Enclosed System: Eliminates leakage and minimizes exposure to the atmosphere, which is critical for sanitary applications and hazardous fluids.
- Scalability: Available in 12-inch and 16-inch diameters with varying cell counts (5 to 18 cells) to match batch size requirements.
- High Solids Loading: The depth media structure absorbs a significant volume of contaminants before reaching terminal pressure.
- Rapid Change-Out: Pre-assembled modules allow for quick installation and removal, significantly reducing downtime compared to manually dressing a filter press.
- Variety of Media: Compatible with various media grades to target specific contaminants, hazes, or biological loads.
Media Configurations
ErtelAlsop cartridges are available with distinct media formulations to suit specific industry needs:
| Media Series | Composition | Primary Application |
|---|---|---|
| MicroMedia® | Cellulose / Perlite / DE | General clarification, haze removal, food & beverage. |
| AlphaMedia® | 100% Cellulose | Pharmaceuticals, applications requiring no inorganic filter aids. |
| MicroClear® | Activated Carbon Immobilized | Color correction, odor removal, decolorization. |
| Zeta-Pak® | Positively Charged Matrix | Bio-reduction, removal of negatively charged contaminants (endotoxins). |
