Complete Guide to ErtelAlsop Pak Lenticular Filters

Optimizing Industrial Filtration with ErtelAlsop Pak® Lenticular Filters

In the landscape of industrial liquid filtration, precision and reliability are paramount. At Purecowater, we understand that achieving the highest purity requires equipment that goes beyond standard specifications. We are proud to feature ErtelAlsop Pak® Lenticular Filters, a premier solution for depth filtration applications ranging from botanical extraction to pharmaceutical processing.

This guide provides a comprehensive overview of the ErtelAlsop Pak® technology, its specifications, and how it can solve complex solid/liquid separation challenges.

What are ErtelAlsop Pak® Lenticular Filters?

The ErtelAlsop Pak® is a depth filter cartridge system, often referred to as a “lenticular” module due to its shape. Unlike standard pleated cartridges that rely primarily on surface filtration, lenticular modules utilize a thick depth media. The Pak® is constructed from multiple filter cells stacked vertically. Each cell consists of two sheets of filter media sealed at the edges, creating a leak-proof module that handles high solids loading with exceptional efficiency.

Lenticular design allows for scalable deep-bed filtration in a compact footprint.

These filters are designed to fit into sealed housings, providing a closed-loop system that eliminates leakage common in traditional plate and frame filter presses. This makes them ideal for applications requiring strict hygiene standards and operator safety.

Key Features and Technologies

1. Advanced Media Options (Zeta-Pak® & Micro-Media®)

The core of the Pak® filter’s performance lies in its media composition. The modules are available in several proprietary formulations:

  • Zeta-Pak®: Incorporates Diatomaceous Earth (DE) and cellulose. This media provides a positive Zeta potential, which electrokinetically attracts negatively charged contaminants like bacteria and endotoxins, removing particles smaller than the mechanical pore size.
  • Micro-Media®: A high-performance depth filter sheet used for clarifying and sterile filtration. It offers superior retention of ultra-fine particles and high flow rates.
  • AlphaMedia®: A cellulose-based media ideal for general-purpose applications where DE is not required.

2. Superior Edge Sealing

One of the distinctive features of the ErtelAlsop Pak® is the patented edge-sealing process. Using polypropylene to seal the outer edges of the filter cells ensures that 100% of the liquid passes through the media, preventing bypass—a critical factor for high-purity filtrate.

3. High Solids Loading Capacity

The depth media matrix captures particles throughout its thickness, not just on the surface. This allows the filter to hold significantly more solid contaminants before fouling, extending the service life and reducing change-out frequency compared to surface filters.

Primary Applications

ErtelAlsop Pak® filters are versatile “workhorses” used across various industries. Their ability to remove haze, lipids, and fine particulates makes them indispensable in:

  • food & Beverage: Haze removal in distilled spirits, wine polishing, and syrup clarification.
  • Botanical Extraction: Highly effective for winterization and removing waxes and lipids from ethanol-based botanical extracts. The large surface area allows for high flow rates during lipid removal.
  • Pharmaceuticals & Cosmetics: Clarification of perfumes, lotions, and active pharmaceutical ingredients (APIs).
  • Chemical Processing: Polishing of specialty chemicals and solvents.

Why Choose ErtelAlsop Pak® for Your System?

Choosing the right depth filter can dramatically optimize your production line. The ErtelAlsop Pak® offers distinct advantages:

  1. User-Friendly Design: The modular cartridge format makes change-outs significantly faster and cleaner than traditional filter presses.
  2. Scalability: Available in 12″ and 16″ diameters with varying cell counts (up to 16 cells), allowing you to scale up from pilot testing to full production easily.
  3. Cost Efficiency: By combining high retention efficiency with long on-stream life, these filters reduce downtime and consumable costs over time.
