Manufacturing filtration – Tetratex Contact ePTFE membrane

For use in manufacturing filtration processes, Tetratex Contact® ePTFE membrane uses surface filtration, which is said to ensure that the majority of fine dust can be easily cleaned down by the existing filter unit’s cleaning mechanism. The dust can then be collected as part of the existing filter unit dust-collection mechanism and re-used.

So says Donaldson Membranes, which has developed the new membrane-filter media for food and pharmaceutical applications. It says these specialised filtration products enable safe product reclamation without fear of contamination from the filter media. With production costs increasing, the benefits of reclaiming products are a vital step in further improving plant cost optimisation, it points out.

Tetratex Contact ePTFE filter media for food and pharmaceutical applications can be reliably integrated into many processing filtration applications, explains Donaldson. Every food-processing application is different, the company says, and carries with it a specific set of challenges. A host of factors can influence the performance of any given fabric filter, so the selection of an appropriate filter media is critical.

Tetratex Contact filter media – said to be compliant to EU regulation 10/2011 and in accordance with FDA CFR 21 § 177 – can meet the high demands of a variety of filtration processes for food contact and pharmaceutical applications.
