What is depth filtration and why is this technology used?
Due to process conditions and raw materials, all manufacturing processes in the Food & Beverage industry related to the production of clear and stable products have unexpected variances in their turbidity and colloidal load. Those variances can have a massive negative impact on the performance of installed filters, especially membrane filters that are installed prior to bottling.
Microbial spoilage contamination is another prevalent concern for most food and beverage manufacturers. The potential impact it can cause may lead to product recalls and compromise consumer safety.
Depth filtration is the ideal solution for such conditions in these applications.

SUPRAdisc™ & SUPRApak™ Depth Filter Modules
Pall’s portfolio of craft beer filtration solutions has been designed to ensure consistent, high-quality products while keeping your production costs low. Our cost-effective and flexible solutions maintain product authenticity, provide high quality, and position craft breweries for increased productivity and expansion.
The SUPRA family is based on sheet technology, combining the advantages of depth filtration with a closed system. There are two product platforms offering safe and gentle clarification of beers with very low beer loss, oxygen uptake and costs.
The SUPRAdisc II filter module is an upgrade of classical lenticular filters. The design enables higher filtration area than traditional lenticulars and improved mechanical stability enabling repeated regeneration which prolongs service life significantly.
The SUPRApak depth filter module combines sheet filter materials with a unique flow configuration that maximizes filtration and adsorption. This provides a very high dirt holding volume combined with a maximum pressure stability, long service life and high packing density.
SUPRApak Depth Filter Modules
Whether you're producing citrus oil or other flavors, we understand that the filtration and separation equipment used in your production must be selective and have the flexibility to reliably remove the different sources of turbidity like colloidal haze, waxes and lipids. However, it's also important that these steps do not negatively influence or reduce quality-enhancing characteristics like aroma and color.
Pall SUPRApak depth filter modules offer an entirely unique design and flow path which forces raw liquid along a significantly longer filtration path before exiting the filter. This "Edge Flow Technology" significantly improves filtration properties and performance compared to conventional flat filter sheets and lenticular modules resulting in higher filtrate quality and better economics.
As well as providing excellent filtrate quality unrivalled with traditional sheet filters, additional benefits of SUPRApak technology include:
Enclosed system for product protection and avoidance of oxygen pickup
High product yield
High throughput at low investment cost
Low labor, maintenance, and downtime costs
Extremely low installation footprint
Easy integration into existing system
High flexibility to integrate the SUPRApak filtration solution into processes from small batches to large scale industrial production volumes
Seitz® AKS FB and SUPRApak™
We understand the challenges of filtering hard seltzer. The base product of hard seltzer is usually from neutral spirits, wine, malt or sugar. Most hard seltzers are clear, colorless beverages. But achieving a colorless, flavorless base is a crucial step that poses considerable challenges:
Hard seltzer can be hazy and have a slight color after fermentation.
Fermentation by-products can negatively affect flavor and odor
Traditional Powdered Activated Carbon (PAC) beds, although effective at decolorization, odor and, trace impurity removal, are labor intensive, have a long contact time, and have significant cleaning costs.
Each of these factors influences the taste profile of hard seltzer. Therefore, the selection of the right filtration technology is crucial.
Activated Carbon
The use of bulk powdered activated carbon (PAC) has significant drawbacks due to the handling of bulk carbon powder, equipment cleaning, and time and costs associated with carbon removal from the process. The new Seitz® AKS FB immobilized carbon filter media addresses these concerns and increases the throughput of your hard seltzer by incorporating activated carbon within a matrix of cellulosic fibers.
Carbon particles are protected from shedding downstream by pairing immobilized carbon media with downstream protective filter papers.
Additionally, our activated carbon filtration fixes color and flavor issues, so that the intermediate product can be blended and added with aroma to produce a crystal clear and pure seltzer that offers great taste and refreshens in the absence of disturbing off-flavors.
Depth Filtration
Filtration of various bases is possible with Pall's SUPRA lenticular module solutions. Our SUPRApak™ lenticular modules offer sheet-based filtration with a filter area higher than most lenticular modules and a unique flow configuration that maximizes filtration and adsorption.

Saving Money and Increasing Value in Your Production
When it comes to cannabis oil extraction, we understand the challenges cannabis oil producers face during the downstream filtration process. These challenges include long periods of time to process, labor intensive change outs, lower yields due to drip losses, difficulty of use and open-air systems that lead to quality and safety concerns.
The depth filtration technology used in the Pall cannabis oil filtration systems solves these challenges, enabling the production of high-quality cannabis oil and ensuring compliance with GMP and FCC standards.
OIL CLARIFICATION

SUPRApak technology
We understand a key challenge facing olive oil producers today is consistently providing high-quality olive oil with processes that are cost-effective and reduce product loss. Reduction in turbidity, moisture and wax content as well as other insoluble impurities are key challenges that need to be addressed during production.
Without adequate filtration steps in place, these elements will affect the appearance and shelf life of olive oil and as a result, affect the perceived quality of the oil in the market.
Pall SUPRApak technology allows olive oil producers to achieve a premium quality, high value oil using an easy to use filtration process. SUPRApak depth filter modules are the next level in the development of the depth filter sheets traditionally used in olive oil filtration.
As well as providing excellent filtrate quality unrivalled with traditional sheet filters, additional benefits of SUPRApak technology include:
Enclosed system for product protection and avoidance of oxygen pickup
High product yield
High throughput at low investment cost
Low labor, maintenance, and downtime costs
Extremely low installation footprint
Easy integration into existing system
High flexibility to integrate the SUPRApak filtration solution into processes from small batches to large scale industrial production volumes
