Have questions about improving your fermentation process? Our team can help you identify the right filtration and clarification solutions for your application.
Fermentation Filtration & Clarification Solutions
Improve fermentation performance with sterile air filtration, stable broth management, and efficient clarification solutions that protect yield and reduce contamination risk.
Filtration’s Role in Fermentation Success
Fermentation for food and ingredient production relies on clean utilities, consistent upstream control, and efficient broth clarification and final filtration to protect batch quality and maximize yield. Our filtration technologies support reliable production across various fermentation derived ingredients. Learn more about filtration for food and ingredients here.
What is Fermentation in Food & Ingredient Manufacturing?
Fermentation relies on controlled microbial processes to generate ingredients such as amino acids, enzymes, organic acids and most recently novel proteins from precision fermentation such as whey, casein, lactoferrin, flavor molecules, sweeteners and egg proteins among others.
Upstream Fermentation Protection
Contamination from upstream utility components such as air, water, nutrients, or steam can interrupt fermentation cycles, reduce product formation, or lead to a complete batch loss, making filtration an essential part of process stability.
Effective upstream control establishes the conditions required for a reliable fermentation run. Sterile air and water, consistent nutrients and protected utilities all contribute to early stage fermentation health and reduce the risk of contamination related shutdowns.

Steam Filtration for Process Integrity
Bacteriophages are one of the main causes of fermentation batch failure and can lead to costly production losses. Sterile filtration of compressed air and tank vents helps ensure clean gas inputs and reduces “dead tank” events. Learn more about air and gas filtration here.
Our Solutions
Water and nutrient feeds may introduce suspended solids or microorganisms that impact culture growth, shorten fermentation cycles or destabilize yields. Pre filtration helps maintain consistency across batches and lowers the burden on downstream clarification. Sterile liquid filtration protects fermentation batches and helps maintain consistent microbial control throughout the process.
Our Solutions
Steam supports sanitization, sterilization, and other utilities across the facility. When steam carries particulates, it can compromise product quality and equipment cleanliness.
Our Solution
PSS® Plus Metal Elements
Durable metal filters providing tight permeability control for culinary grade steam.
Learn how our advanced solutions support fermentation from start to finish, from protecting processes with air and gas filtration to improving downstream efficiency through broth clarification
Downstream Processing
After fermentation, the broth contains product mixed with cells and suspended solids. Efficient clarification is critical to protect downstream purification steps, ensure consistent throughput, and maximize recovery.
Clarification for High Value Ingredients
Ceramic membrane systems operate in fully enclosed and hygienic configurations enabling limited operator exposure and supports automated control. These systems also deliver consistent flux and transmembrane pressure which becomes increasingly important when scaling production or processing higher density broths.
Our Solutions
Membralox® GP-IC Ceramic Membrane Systems
Provides selective, high transmission (up to ~95%) for challenging or premium fermentation ingredients.
Membralox IC Ceramic Membranes
DE free ceramic clarification with controlled permeation and hygienic enclosed design.
Final Filtration
Final filtration ensures microbial stability and product consistency. These steps protect finished goods before storage or packaging and reduce the risk of contamination during late stage handling.

Frequently Asked Questions
How do you prevent contamination in fermentation?
Contamination is minimized by filtering air, water, steam, and feed streams. Emflon® air filters, Profile® Star pre filters, PSS® Plus steam elements and Fuente II sterile liquid filters all contribute to upstream protection.
Why is fermentation broth clarification important?
Clarification removes cells and solids, protects downstream equipment, and increases recovery efficiency. Membralox® IC and GP-IC provide DE free clarification in enclosed, hygienic systems.
What final filtration is used before packaging?
Final microbial reduction is achieved with SUPRAdisc™ II, Fuente II and Supor® Beverage filters, supporting product consistency before packaging.
