Fermentation Filtration

Key Features of Our Fermentation Solutions

Graver Technologies supports a full range of upstream and downstream needs with filtration solutions engineered for consistent performance and batch protection. Each feature below reflects the requirements of modern microbial and pharmaceutical fermentation processing.

• ‍High-integrity sterile barriers: Our solutions strengthen sterile filtration in fermentation by blocking unwanted microorganisms before they reach the vessel. Bacteria removal filter cartridges help maintain controlled environments across both microbial and biopharmaceutical fermentation filtration steps.‍
• Stable media quality and particle control: Industrial fermentation filters support steady flow and media consistency. Fermentation media filtration reduces fine solids that can inhibit growth, while clarifying filters for fermentation improve downstream clarity and reduce load on polishing systems.‍
• Support for bioreactor performance: Bioreactor filtration solutions help manage air, gases, and liquid transfers without upsetting culture balance. ‍
• Compatibility with regulated production: Our products align with pharmaceutical fermentation processing needs, offering materials and construction that fit demanding regulatory expectations while helping protect product purity throughout the run.

Our Filtration Solutions for the Fermentation Process

Graver Technologies offers a selection of filters and housings engineered to protect every stage of fermentation. Each product supports clean media, controlled microbial loads, and stable process performance.

• ‍GHP™ Series Filter Housings: Built for demanding process environments, these housings provide secure containment and dependable flow conditions. They support sterile gas, liquid, and vent filtration commonly used in fermentation steps, ensuring steady operation across varied production scales.
• TefTEC™ P: This membrane series is suited for gas and vent applications. It provides stable retention of airborne contaminants that can threaten culture integrity. Its hydrophobic structure supports consistent airflow in bioreactors and transfer systems.
• TefTEC™ V: A strong choice for venting and air-handling needs where moisture and particulate control matter. It helps maintain the clean pressure balance in vessels while supporting long runs without performance drift.
• ZTEC™ B: Designed for microbial retention, this cartridge is effective for reducing bioburden in liquids used throughout fermentation. It supports media preparation, buffer conditioning, and other process steps where reliable microorganism control is required.
• ZTEC™ P: This membrane cartridge helps deliver final filtration of liquids before they enter the reactor or move downstream. It supports clarity, particle removal, and batch consistency across a range of fermentation applications.
• CelluTEC® Dual Layer Depth Filters: These dual layer depth filters combine cellulosic media with DE and polypropylene to support upstream fermentation filtration. Designed for high loading applications, they effectively remove larger suspended solids and protect downstream membranes, helping maintain media clarity and stable fermentation performance.
• QMA™ Series Cartridges: The QMA™ pleated media filters deliver absolute rated liquid filtration that enhances the quality of fermentation broths and intermediates. These cartridges reduce fine particles and impurities prior to bioreactor feeds, improving process consistency and extending the life of finer downstream filters.
• ZTEC™ B / SLB Membrane Cartridges: ZTEC™ B and SLB membrane cartridges provide reliable bioburden reduction for liquid streams used throughout the fermentation process. Their hydrophilic PES membranes support consistent microorganism control, helping ensure clean media inputs and reducing contamination risks in fermentation batches.

Applications of Industrial Fermentation Filters

Graver Technologies supports a wide range of fermentation-driven operations, providing filtration systems that stabilize process conditions and protect product quality. These solutions strengthen microbial control, media purity, and downstream clarity across several key industries.

• Biopharmaceutical Manufacturing: Producers rely on consistent sterile barriers and reliable media conditioning to support cell culture, microbial fermentation, and enzyme expression. Our systems help maintain purity throughout upstream and downstream workflows.
• Food and Beverage: Fermentation used in brewing, dairy, nutraceuticals, and ingredient production benefits from dependable particulate and microbial reduction. This supports stable flavor, texture, and overall product uniformity.
• Industrial Biotechnology and Enzyme Production: Companies focused on biochemical conversion, specialty enzymes, and large-scale fermentation processes use our filtration solutions to manage solids, maintain flow, and protect reactors from contamination.
• Chemical and Specialty Processing: Fermentation-driven chemical synthesis requires clean inputs and protected transfer lines. Our filters help improve consistency across both pilot-scale and full production environments.
• Healthcare and Diagnostics: Producers of therapeutic proteins, vaccines, and diagnostic reagents depend on controlled fermentation steps supported by clean, reliable filtration systems.
