Advanced Depth Filtration with ErtelAlsop Pak® Technology
For industrial applications requiring high-efficiency particulate removal and fluid clarification, ErtelAlsop Pak® Lenticular Filters provide a superior depth filtration solution. As a distributor for top-tier filtration manufacturers, Purecowater offers these versatile modules to address complex solid-liquid separation challenges. Whether you are dealing with botanical extracts, distilled spirits, or pharmaceutical APIs, the Pak® system is designed to streamline your process.
Lenticular filtration bridges the gap between traditional plate and frame filters and modern cartridge systems. By utilizing the Zeta-Pak® media in a sealed, convenient module, operators gain the retention performance of depth media with the ease of use associated with cartridge change-outs.
The Zeta-Pak® Advantage
The core of this technology is the Zeta-Pak® lenticular module. These filters are constructed using Micro-Media®, which incorporates cellulose, high-purity filter aids (such as Diatomaceous Earth or Perlite), and wet strength resins. This composition creates a rigid, porous filter cake capable of retaining ultra-fine particles through both mechanical sieving and electrokinetic adsorption (zeta potential) [clearsolutionscorp.com].
Key benefits of the Zeta-Pak® series include:
- High Solids Capacity: Ideal for protecting downstream membrane filters by removing bulk solids.
- Superior Haze Removal: Excellent for polishing applications in spirits and oils.
- Leak-Free Design: The modules fit into sealed housings, eliminating the edge leakage often found in filter presses.
- Botanical Extraction Efficiency: Specifically cited for its ability to remove waxes and lipids from extracts while maintaining high flow rates [clearsolutionscorp.com].

System Housings
To maximize the performance of ErtelAlsop Pak® filters, they are typically paired with specialized stainless steel housings. These housings ensure proper sealing and flow distribution.
- Vertical Domed Housings: The standard for most applications, available in various heights to accommodate 1 to 4 stacked modules. Features a sanitary design with V-Band clamp closures [ertelalsop.com].
- Horizontal Housings: Designed for ergonomic loading at waist height. These allow for single-operator use and eliminate the need for overhead hoists, making them ideal for facilities with height restrictions [ertelalsop.com].
