Microfiltration is used in membrane filtration for the separation and production of products from 5 micron down to 0.10 micron, with most membranes being used between 1.0 micron and 0.2 micron. H&V’s Trupor® product line is available at industry-standard pore sizes — 5.0 μm, 1.2 μm, 0.80 μm, 0.65 μm, 0.45 μm, and 0.20 μm.  

Due to the crucial nature of the microfiltration processes in their production, membrane reliability and robustness are critical. The microfiltration industry uses proven materials like nylon, polyethersulfone (PES), and polyvinylidene fluoride (PVDF). 

Trupor® delivers on H&V’s two centuries of fiber-based innovation and is available in nylon and other polymers. It fills all the conventional expectations of a microfiltration membrane, including: 

  • Reliable, consistent pore sizes
  • All Trupor® products are produced at ISO 9001 facilities under H&V’s adopted version of Hazard Analysis Critical Control Points (HACCP) to meet customer and end application safety expectations
  • Diffusion testable
  • Fluid treatment without heat, to preserve valuable products
  • Chemical-free treatment
  • Cost-effective treatment using established processes
  • Low protein binding
  • Suitable for single-use systems (SuS) or where cleaning is needed
  • Cleanable using steam sterilization or gamma irradiation depending on the polymer family

Microfiltration media is often integrated with other filtration layers to form a composite; spunbonds, meltblowns, and meshes are commonly used in microfiltration cartridges. 

What Are Some Common Uses of Microfiltration Media?

We offer a diverse range of membrane, meltblown, microfiber glass, and composite filter media to suit different industry applications. Typical end-uses include:

  • Water filtration
  • Industrial filtration
  • Semiconductor processing 
  • Biopharmaceutical production
  • Bottled water
  • Beer and wine
  • Waterborne pathogen removal
  • Chemical mechanical processing (CMP)
  • Electromechanical deposition (EMD) of materials
  • Ink and dye production
  • Buffer water production

H&V Membrane Form Factors & Filtration Mechanisms

H&V microfiltration membranes are used in many form factors:

  • Pleated cartridges. By area, conventional industry cartridges at 10-inch lengths are the most common use of microfiltration membranes.
  • Analytical and small form factor. Microfiltration membranes are often used in small form factors for analytical and testing capabilities.
  • Spiral wound cartridges. Microfiltration is growing in its use of spiral wound elements. Historically, these were mostly used for desalination and reverse osmosis.

They use the following filtration mechanisms:

  • Tangential or cross-flow filtration
  • Dead-end filtration
