Trupor® microfiltration media delivers membrane reliability with superior performance. The innovative composite design uses standard polymers (Nylon and a PES-PBT composite) to deliver long life, stable performance, and superior pore size uniformity.
Trupor® can be used in cartridges just like current porous materials – it pleats on industry standard equipment and can be used as a final efficiency layer, or upstream of an efficiency layer to add capacity and life. Reference cartridge designs are available upon request.
Why does microfiltration matter?
Demand for liquid filtration processes, and the products they enable, grow every year – microfiltration is an enabler of many growing parts of the global economy.
Food, beverage, bioprocess, industrial, and water treatment industries benefit from improved microfiltration.
Improving microfiltration makes it possible to bring new products to market, to make existing fluid streams safer, to reduce dependence on additives, and to improve processing times for products.
- Particle filtration is used to remove particles 10 micron and larger
- Microfiltration (“MF”) is used with materials between 0.10 and 10 micron
- Trupor® is used in microfiltration
- Ultrafiltration (“UF”) is used with materials between 0.005 to 0.10 micron
- Nanofiltration (“NF”) is used with particles between 0.001 and 0.015 micron
- Reverse Osmosis (“RO”) is a special class of nanofiltration, where salt ions, or other similar sized materials, are removed from water
How is microfiltration used?
Microfiltration is an important step in fluid processing that enables many industries.
Food and beverage makers use microfiltration to:
- Produce products quickly and at lower costs
- Develop new products to meet shifting consumer tastes
- Remove microorganisms and contaminants, reducing dependence on preservatives and additives to extend shelf life and improve taste
Products made using bioprocessing, including biopharmaceuticals, depend on microfiltration to harvest proteins and other therapeutics, such as:
- Improving flux and flow rates in microfiltration steps leads to improved processing times – this leads to improved yields and improved titer in final products
- Microfiltration ensures that waste products are removed from product streams
- Sterilizing grade filters (a special class of microfiltration products at the 0.1, 0.2 and 0.45 micron grades) are used to ensure product safety, and make sure that microorganisms don’t enter the product stream
- Microfiltration is used in many bioprocessing and biopharmaceutical production steps; buffer production, harvest, water-for-injection (“WFI”), final fill, and many more
Industrial processes depend on microfiltration to:
- Remove fine particulates, such as fine silicon dust in Chemical Mechanical Polishing (“CMP”) in the semiconductor industry
- Ensure fluid quality, such as that used in baths for electroplating and electrical discharge machining (“EDM”)
- Produce inks, dyes, and other colorants
For water treatment, Trupor®’s improved performance allows broader incorporation of microfiltration into treatment processes:
- Microfiltration is used to protect downstream UF, NF and RO process in treatment trains
- Microfiltration is used to improve new approaches to water re-use, both for municipalities and industrial users
- Microfiltration can be a critical part of water treatment for drinking water (point-of-use “POU” and point-of-entry “POE”), desalination pretreatment, water reuse, boiler feed, discharge water, and cooling towers
