Mott’s bioprocessing filter is designed for clean-in-place performance, meaning filter elements can discharge cake build-up without having to open the filter for maintenance. Once a terminal pressure drop has been reached, the cleaning cycle automatically initiates to discharge cake build-up through gas assisted pulse or through a backwash cycle.

Particles will embed in the filter media over time, requiring the elements to be cleaned by a third-party company. Various cleaning techniques can be used to prolong life of the elements. For a recommendation of a cleaning company, please contact a Mott representative. It is recommended you keep a spare set of filter elements to continue operations while elements are being cleaned.

The Mott Filter Design Process

  1. Filter Feasibility Testing – In our Customer Innovation Center, we will replicate, or very closely correlate, your process conditions to determine the appropriate media grade and material for your bioprocessing filters application. We will provide you with a comprehensive, in-depth analysis to prove the feasibility of using porous metal bioprocessing filters in your process and furnish you with a comprehensive ROI justification.
  2. Pilot Testing – As an option, we can install a pilot unit in your facility enabling you to witness, first-hand, how our bioprocessing filters will perform in your process stream and under your actual operating temperatures and pressure conditions.
  3. Front-End Engineering Design – Our Front-End Engineering Design (FEED) process provides you with a complete process engineering package for bioprocessing filters, including vessel drawings, a preliminary equipment layout drawing, piping and instrumentation diagram, process flow diagram, valve and instrument list, and a detailed process functional description.
  4. Fabrication – When it comes to fabricating your system, we can handle as much or as little as you need – from fabricating only the filter vessel for bioprocessing filters, to providing a complete turnkey skid system.
  5. Operational Support – When your filtration system is complete, our professionals can provide equipment commissioning and startup services, training, ongoing technical support, and quality assurance testing for the life of your bioprocessing filters system.

Depending on your needs, Mott can provide just the filter elements, a vessel and elements, or provide you a full turnkey system with the vessel, frame, piping, instruments, and controls for bioprocessing filters.

FAQs: Bioprocessing Filter

Q: What is a bioprocessing filter?

A: A bioprocessing filter is a specialized filtration device designed for use in the biopharmaceutical industry to separate and purify biological materials, such as cells, proteins, and nucleic acids, during the bioprocessing stages. These filters are engineered to meet the stringent standards of purity, efficiency, and reliability required in biomanufacturing processes.

Q: How do bioprocessing filters improve production efficiency?

A: Bioprocessing filters improve production efficiency by enabling the effective separation of desired biological components from culture media or process streams. This results in higher product yields, reduced process times, and lower costs by minimizing the need for further purification steps. Their design also supports consistent performance under a range of process conditions, including high pressures and temperatures.

Q: Can bioprocessing filters be used for all types of bioprocesses?

A: Yes, bioprocessing filters are versatile and can be used in a variety of bioprocesses, including fermentation, cell culture, and downstream processing. They are suitable for a wide range of applications, from small-scale laboratory research to large-scale commercial production, and can be customized to meet the specific requirements of different biological materials and process conditions.

Q: Are bioprocessing filters compatible with high-temperature processes?

A: Bioprocessing filters are designed using materials that can withstand high temperatures, making them compatible with processes that require sterilization or involve high-temperature operations. The specific temperature range and compatibility depend on the materials used in the filter construction, so it’s important to select a filter that matches the process requirements.

Q: How are bioprocessing filters maintained?

A: Maintenance of bioprocessing filters typically involves regular cleaning and sterilization to prevent clogging and maintain filter integrity. Many bioprocessing filters are designed for single-use to eliminate cross-contamination risks, while reusable filters can often be autoclaved or cleaned with appropriate solutions. The specific maintenance procedures depend on the filter design and the manufacturer’s recommendations.
