Polymeric Filters

Polymeric Filtration Systems

Polymeric filters play a crucial role in filtration solutions, because of their low cost in the filtration products ecosystem. They come in various forms, like filter bags, cartridges – both wound filter cartridge and spun, as well as plain pieces cut as per requirement.

Types of Polymeric Filters

Choosing the right polymeric filter depends on various factors, including the chemistry of the fluid to be filtered, the desired level of filtration, and the operating conditions. With the proper selection and implementation, polymeric filters can significantly contribute to a successful r filtration process.

Polymeric PTFE

PTFE Membrane Filters

  • Made from PTFE (polytetrafluoroethylene), commonly known as Teflon.
  • Highly resistant to chemicals: Ideal for filtering aggressive solutions.
  • Hydrophobic: repels water, allowing gases and air to pass through. Can be modified to be hydrophilic for specific needs.
  • High temperature tolerance: suitable for hot filtration processes and sterilization.
  • Low-binding properties: minimize sample loss on the filter surface.
  • High porosity: allow for fast flow rates while maintaining efficient filtration.

Polymeric PP

PP Filters

  • Cost-effective and versatile option.
  • Made from polypropylene, offering good chemical resistance.
  • Good thermal stability for moderate temperatures.
  • High dirt holding capacity for extended use.
  • Primarily used for pre-filtration, water clarification, and food/beverage filtration.
  • Choose based on pore size, chemical compatibility, temperature requirements, and desired micron rating.

Polymeric Nylon Bag

Nylon Filter Bag

  • Type: Reusable filter media used in conjunction with other filtration systems.
  • Material: Strong and versatile nylon mesh.
  • Function: Captures particles of specific sizes while allowing liquid to flow through.
  • Completely customizable as per client’s process requirements

Polymeric Cotton Bag

Cotton Filter Bag

  • Pre-filtration solution for polymeric filters: Extend lifespan and improve performance of downstream filters.
  • Capture large particles: Dust, debris, fibers, protecting finer polymeric filter media.
  • Cost-effective: Less expensive than many polymeric filters.
  • Biodegradable fabric: Filters made from this completely biodegradable material offer a way to reduce your company’s carbon footprint and improve your sustainability quotient.

Benefits Of Polymeric Filtration Systems

Increased production efficiency

Efficient filtration minimizes downtime and production bottlenecks.

Reduced manufacturing costs

Lower filter OPEX costs compared to stainless steel filters, if the particle content in your incoming stream is low

Absolute filtration

Membrane filters made out of polymers such as PTFE/PES are integrity-testable, which makes them the only type of testable absolute filter, essential for pharmaceuticals.

Applications of Polymeric Filters

Owing to their inexpensive nature, they are a first choice for many customers looking for prefiltration or to filter out impurities in low value products. Some applications are listed below:

Side stream filters for cooling towers

Prefilters for RO systems

Capturing powders in nutraceutical manufacturing

Why Choose Kumar Process Consultants?

We consider your entire process and offer the best solution with regards to both, CAPEX and OPEX. A correct choice of disposable and reusable filters can save your company a lot of money in the long run. Additionally, our team is able to recommend the correct materials to be used for the filters, so that filter bypass is eliminated due to dissolution/softening of the polymeric materials or due to swelling of the sealing gaskets.
