Pall Enables Sustainable Food Production at a Lower Cost with Membralox®
Pall Corporation, a leading provider of filtration, separation and purification solutions launched Membralox® GP-IC ceramic membrane systems, a revolutionary ceramic membrane with graduated permeability along the length of the filter. This unique design increases processing efficiency, lowers capital and operating costs and has the potential to yield up to 95% recovered value-add products enhancing overall filtration performance.
With a high surface area and multi-channel geometry, the Membralox GP-IC membranes offer up to 45% more filtration capacity compared to conventional ceramic filters of similar size. This enables optimized system loop design with more compact filter modules, reducing capital and operational expense.
“The unique design of Membralox GP-IC pushes the boundaries of what’s possible for ceramic membrane solutions in order to meet the demands of food processors globally,” said Ankush Soni, Vice President & General Manager of the Food and Beverage business unit of Pall Corporation. “We are excited to launch this breakthrough solution and support our customers with a smarter, more efficient and sustainable solution.”
Pall has a long history of expertise and innovation in the ceramic membrane industry, which is poised for exponential growth ($21 billion by 20301). Through filtration expertise as well as a deep understanding of the unique challenges of global food industry, Pall was able to design a solution enables customers to be at the forefront of sustainable and efficient food production.
Rensa Filtration acquires Irema-Filter of Germany
Rensa Filtration, an Audax Private Equity portfolio company and manufacturer and distributor of consumable, mission-critical air filtration solutions, announced that it recently acquired IREMA-Filter GmbH and its U.S. subsidiary Aeolus Filter Corporation from PINOVA Capital.
IREMA was founded 50 years ago near Postbauer-Heng, Germany and is an innovator in filtration media and filter media pleating technologies. Based in Archdale, NC, Aeolus Filter provides filters using IREMA’s media and pleating technologies and has a strong market presence in critical data center and healthcare air filtration applications.
Brandon Ost, CEO and Founder of Rensa Filtration, noted, “We’re excited to partner with the IREMA and Aeolus management team, employees and their customers. The filtration market has long held the IREMA/Aeolus business and filter technology in high regard, and we look forward to supporting their continued technology development, increased manufacturing capacity and commercial growth. This investment in IREMA underscores Rensa’s commitment to quality and innovation.”
IREMA’s filter media process technology is a flexible platform capable of making both polymeric microfibers and nanofibers and combining them to make innovative filter media structures with multiple layers, gradient structures, and mixed micro and nanofiber structures. For end users, these technologies enhance both the dust-holding capacity and service life. The media can be electrostatically charged or fully mechanical in nature. Because it is completely polymeric, the media has high moisture resistance and mechanical durability and does not support microbial growth. Finished filters can be recycled or sent to waste-to-energy facilities.
FLS to Deliver the World’s Largest Filtered Tailings System
Following a long-standing partnership, a progressive Indian miner and steelmaker has selected FLS to deliver core mining technologies to what is set to become one of the world’s largest, most efficient and sustainable iron ore beneficiation plants globally. This is the fourth consecutive order that FLS has received from the customer within the past nine months.
The order includes the delivery of the world’s largest filtered tailings (“dry tailings”) system comprising of twenty-two 4.2-meter x 162-sq. meter Horizontal Belt Filters (HFB), which also will be the largest of their kind in the world, as well as twelve 12 x 55-meter diameter high-rate thickeners (HRT). The technologies are expected to be delivered to the customer in 2026.
The addition of these technologies to the flowsheet and their crucial placement throughout the overall process flow demonstrates FLS’s commitment to sustainability, in this case, particularly water recovery. Furthermore, this order confirms FLS’s technology as the preferred solution for resource conservation and operational efficiency.
The value of the order has not been disclosed.

ZwitterCo Launches Evolution Membranes, Transforming Dairy and Food Processing Efficiency
ZwitterCo, a global leader in membrane solutions for challenging liquid separations, has announced the commercial release of its Evolution membrane product family. These next-generation membranes are engineered to help food, dairy, and biotech processors increase productivity, reduce cleaning costs, and advance sustainability objectives—all without requiring changes to existing systems.
In dairy and food processing, every minute counts, but lengthy daily cleanings can consume valuable production time and significantly increase chemical consumption and water demand. Evolution membranes, built with ZwitterCo’s patented zwitterionic chemistry, are anti-fouling and fully recover performance with a simplified cleaning program. This enables processors to clean faster, use fewer chemicals, and reclaim over an hour per day for additional production or other high-value tasks.
Available in an ultrafiltration membrane for protein concentration (PCM), superfiltration (SF), and reverse osmosis (RO) membrane configurations, Evolution membranes are one-for-one replacements for conventional sanitary spiral membranes. They install easily in existing systems with no hardware changes needed to experience lower operational costs and time savings.
