High-Capacity Depth Filtration for Critical Applications
For industries requiring rigorous liquid clarification and solids removal, ErtelAlsop Pak® Lenticular Filters provide a robust and efficient solution. As a distributor for leading filtration technologies, Purecowater offers these depth filter modules to replace traditional plate and frame methodologies with a user-friendly, enclosed system.
The Lenticular Pak® cartridge (or module) is designed to retain particles and contaminants through a complex matrix of fibers and filter aids. This technology is ideal for applications ranging from pharmaceutical processing to botanical extraction, offering high solids loading capacity and superior retention efficiencies.
What Is a Lenticular Pak® Filter?
The ErtelAlsop Pak® consists of multiple depth filter cells stacked vertically. Each cell is constructed from a pair of MicroMedia®, AlphaMedia®, or MicroClear® sheets, sealed at the edges using a patented polypropylene process. This assembly creates a \”double convex lens\” shape—hence the name provided by the source ertelalsop.com.
Unlike surface filters that only trap particles on the exterior, these depth filters trap contaminants throughout the thickness of the media. This results in:
- Higher Dirt Holding Capacity: The complex fiber matrix allows for significant solids accumulation before reaching terminal pressure.
- Positive Zeta Potential: Many ErtelAlsop media options exhibit a positive charge (Zeta Potential), allowing them to electrokinetically attract negatively charged particles (like endotoxins or haze colloids) that are smaller than the physical pore size store.ertelalsop.com.
Technical Specifications
Purecowater provides ErtelAlsop modules in standard industrial configurations to ensure compatibility with existing housings. These modules act as a direct upgrade for open plate and frame systems by enclosing the media in a sealed housing, eliminating leakage and preventing external contamination.

Key Applications and Industries
ErtelAlsop cartridges are tailored for critical processes where product purity is non-negotiable.
1. Botanical and Herbal Extraction
Lenticular modules are a standard in the dewaxing and winterization of botanical extracts. The Zeta-Pak® modules, often impregnated with Diatomaceous Earth (DE), form a rigid, porous structure that efficiently sieves out lipids and waxes while removing fine particulate matter. This ensures a clean, polished oil or tincture without affecting flavor profiles.
2. Pharmaceuticals and Cosmetics
For hygienic applications, these modules offer a closed system that drastically reduces exposure to the environment compared to open plate presses. They are typically used for:
- Clarification of syrups and serums
- Protection of downstream membrane filters
- removal of carbon fines
3. Food and Beverage
From distilled spirits to sugar syrups, the Pak® cartridges remove haze and sediment. The availability of various grades allows operators to dial in the clarity required for shelf-stable beverages.
Why Upgrade to Lenticular Filtration?
Many facilities operate legacy Plate and Frame filters. While effective, they can be labor-intensive and prone to leakage. Upgrading to ErtelAlsop Pak® Lenticular Filters through Purecowater offers distinct advantages:
- Reduced Downtime: Change-outs take minutes rather than hours.
- Zero Leakage: O-ring seals and enclosed vessels prevent product loss.
- Scalability: The modular design allows you to add or remove height to the housing stack to adjust surface area requirements.
Get a Solution for Your Process
Whether you require the high zeta potential of the Zeta-Pak® or the carbon treatment capabilities of MicroClear®, Purecowater can engineer the correct housing and module combination for your flow rate and solid yield.
