Let’s begin with Liquid Filtration . An essential step in the brewing process, as it helps to remove unwanted particles from the beer and ensure that it is clear and visually appealing to consumers. Suspended solids, such as yeast, grains, and other contaminants, can negatively afect the overall taste and appearance of the beer. ultraflters range of cartridges and housings provide solutions for any brewing application.
Filtration is also important for maintaining consistency in the brewing process. By utilizing fltration, brewers can ensure that their beer meets a specifc, and consistent standard every time it is produced. This is crucial for large-scale operations and for beer brands that are looking to establish a consistent taste and quality across their portfolio.
Utilizing the correct type and grade of fltration can also help to extend the shelf life of beer by removing impurities that can lead to spoilage or undesirable favors. This not only ensures that consumers are receiving
The most common style of flter, is depth fltration: This type of fltration is often used to capture and prevent larger particles and suspended solids, such as Diatomaceous Earth (DE), from entering the Bright Tank.
Surface fltration: In this type of fltration, the liquid is passed over a flter membrane, which traps particles on its surface. It is efective for removing smaller particles but can be costly and may require additional processing steps to remove trapped particles from the membrane.
Centrifugal fltration: This method uses centrifugal force to separate solids from liquids. It is efective for removing heavy particles but may not be as effective for very fne particulates.
Crossfow fltration: This technique uses a flter media that allows the liquid to pass through, while particles are trapped and removed from the system.
Overall, the choice of fltration method will depend on the specifc needs of the brewery and the goals of the brewing process. Our team ofer no charge discovery calls to assess what will suit your brewery the best. From our experience, the biggest liquid fltration challenges facing a master brewer today are related to process efciency, consistency, and quality control. Here are some of the specifc challenges that brewers face. How do these compare to your own challenges?
Efciency: Liquid fltration can be a time and resource-intensive process that slows down the overall brewing process. Brewers need to strike a balance between the speed of fltration and the efectiveness of the purifcation process. Solutions to improve fltration efciency include optimizing conditions, streamlining fltration protocols, and using the right type and size of flter technology for specifc application(s).
Consistency: We often receive feedback from brewers stating that they struggle to ensure that the quality and taste profle of the beer remains consistent from batch to batch. Filtration is an important part of this consistency process, but at the same time we need to be cognisant that fltration does not inadvertently alter the favor and aroma of the beer.
Quality control: Another challenge is ensuring that the beer is free from contaminants, such as bacteria and yeast, as these can negatively impact the quality of the fnished product. Brewers need to have robust quality control programs in place to ensure that fltration is removing unwanted particles and that the fnal product meets their quality specifcations on a consistent basis.
With ultraflters validated, and DOP tested range of cartridges, we ensure and guarantee a repeatable, measured consistency of performance.
Cost: Filtration can be an expensive consumable for breweries, especially if they are processing large volumes of liquid. A balance between the benefts of fltration and the cost of the setup and operation of the purifcation process are essential. Some fltration methods, such as depth fltration, can be carried out with relatively low capital and operating costs, while other methods, such as carbon fltration, require signifcant capital investment. The ultraflter team consult with you to ensure that the housings and cartridges are correctly sized, while selecting satisfactory micron ratings. Factory direct pricing enables us to drive your fltration costs down, while always retaining fltration integrity and efciency.
Lead time challenges: These are a major issue for brewers, “and purchasers alike when it comes to liquid flter cartridges.

Common ones include:
• Limited availability: Some flter cartridge types may only be available from a few suppliers, and those suppliers may have limited stock of the flter cartridges. This can lead to longer lead times, especially if the cartridges need to be shipped from overseas or made to order.
• Unpredictable demand and consumption: Brewers may experience sudden spikes in demand for their beer, which can put a strain on their production and subsequently the fltration supply chain. If they do not have enough flter cartridges on hand to meet demand, they may experience production downtime or delays.
• Customization needs: Some brewers may require custom flter car- tridge designs to meet their specifc fltration needs. This can increase lead times, and costs, as the cartridges may need to be manufactured to order.

• Shipping delays: Transportation delays became the # 1 complaint during the recent pandemic. In addition, moving products can be afected by weather conditions, labour strikes, transportation, and logistical issues.
At ultraflter we have invested in a “Double Order Program”, whereby we process exactly what you order and then duplicate the quantities you ordered for our own inventory purposes. This ensures that we have the cartridges you consume in stock the next time you need them. We call it ultraplanning. It’s a Value Added Program we ofer to assist you in over- coming supply chain challenges.
The ultraplanning process begins with ultraflter performing a no charge discovery call to identify the fltration you are currently using. We list each housing, its point of use and the cartridge or element details associated to each one.
Next, we survey the stores area, or inventory crib, to take stock of the on-site filter inventory.
Together we discuss and agree on min/ max levels, and our objective is to guarantee zero outages
Note: We often identify duplicated inventory, where person X purchased part # 1234, and person Y used a diferent supplier to purchase a similar product but with a diferent nomenclature/part #.
Everything is catalogued to ensure that we achieve:
CFIA and other industry related audits are a breeze when it comes to demonstrating flter change out times, dates, and completion, as ultraplanning documents everything, within the program.
A consistent and reliable supply chain of flter cartridges, from a single source.

Forecasted demand, with recommended change out dates. Replacement flters can be ordered, and delivered well in advance to ensure an adequate supply is always maintained and available.
Optimized cartridge usage and on-site inventory, to eliminate inventory duplicates, and reduce the need for unnecessary replacements. This will also negate against lead time delays.
Explore and consider alternative filtration methods, to lower filtration costs and multiple inventory filter types and styles.
Fixed pricing, over a term to be agreed upon, so as price increases and market volatility don’t afect the agreed ultraplanning program prices.
Sterile compressed air is an important input in the brewing process as it ensures the elimination of contaminants, such as bacteria and mold, which can negatively impact the quality of the beer. The use of sterile compressed air is critical for maintaining consistency and reliability in the brewing process. Here are some of the ways that sterile compressed air is used in brewing:
Carbonation: Compressed air is used for carbonation of beer and other beverages. Sterilized compressed air is used to force carbon dioxide into the beer in order to give it the characteristic efervescence and head.
Fermentation: Sterile compressed air is used during the fermentation process to introduce oxygen and circulate the wort. This helps to encourage the growth of healthy yeast and other microorganisms, which play a critical role in the fermentation process.
Bottling and kegging: Sterile compressed air is used during the bottling and kegging process to ensure that no contaminants, such as bacteria or fungi, are introduced into the beer. This helps to ensure that the beer maintains its integrity and favor profle, which is critical for maintaining customer satisfaction.

To ensure that compressed air is sterile, brewers use ultraflters P-SRF range of 0.2µ, steam sterilizable flters. The P-SRF should be protected by pre flters to remove contaminants such as moisture, oil, and particulate The P-SRF can be steam sterilized 100 times, guaranteed, or autoclaved.
Brewery bottle washing involves a cleaning process that typically uses a combination of mechanical and chemical methods to remove impurities and contaminants from bottles prior to flling them with beer. One common method of fltration used in brewery bottle washing is a multi-stage fltration process that includes the following steps:
Pre-fltration: The frst stage involves coarse pre-fltration to remove large particles and debris such as labels and bottle caps. This step is crucial to protect downstream fltration stages from clogging.
Carbon fltration: The next stage involves carbon fltration to remove organic matter and other impurities, such as odors, that could afect the favor and aroma of the beer.
Fine fltration: This fnal stage involves fne fltration, where a flter cartridge with smaller micron pore sizes is used to capture any remaining particles and bacteria that could be harmful to the beer.
Overall, the combination of these diferent types of fltration is efective at providing a thorough cleaning process that removes impurities and ensures that the bottles are clean and ready for beer flling. Each brewery may use slightly diferent approaches to bottle cleaning depending on their specifc needs and preferences.
