Contec membrane filter elements

To meet the highest purity requirements in the chemicals, pharmaceuticals and electronics industries, Contec makes quality standards the highest priority. The superiority of PTFE/FEP/PFA for especially critical process applications has been known for many years. PTFE features universal chemical resistance, high temperature resistance and no extractable constituents.

The COLF (Contec liquid filters) FF filter elements can be pre-flushed at 18 MΩ (optional).
Each filter element is manufactured in a cleanroom and its integrity checked before shipment.

FAQs

Membrane filters enable the very fine and precise removal of particles and microorganisms. Depending on the type of membrane, they can be used for microfiltration, ultrafiltration or sterile filtration.

In membrane filtration, a porous membrane performs the specified separation function.

A distinction is made between

  • Microfiltration (pore size approx. 0.1–10 µm) and
  • Ultrafiltration (pore sizes approx. 0.001 – 0.1 µm)

Most of the separation takes place on the membrane surface. The average membrane pore size essentially determines the separation effect.

Membrane filters are always used when a high degree of purity is required for the suspension to be filtered. Membrane filters are most cost-effective when the particle load in the suspension to be filtered is very low. Thus there should be pre-filtering to protect the high-quality membrane filter elements from clogging too quickly. 

An integrity test checks whether the membrane and filter element are undamaged in accordance with specified criteria. Depending on the component and the application, tests such as bubble-point, diffusion or pressure-retention tests are used, for example. Test procedures and limit values must be specified by the component manufacturer and validated for the process.

Membrane filters have a wide range of applications.

They include the following:

  • water treatment (ultra-pure water, demineralized water
  • pharmaceutical products
  • food
  • beverages (wine, beer, spirits, sparkling wine, mineral water, etc.)
  • cosmetics
  • high-purity chemicals
  • photoresist
  • ink
  • as a terminal filter
