  • High performance microbiological filter

    Filtration processes are a large cost component of pharmaceutical manufacture. The particle retention efficiency, particle capacity of the filter and the liquid flux all impact on product cost. A non woven electropositive filler media has been developed whose active component is an alumina (AlOOH) fiber two nanometers in diameter and having a surface area of 350-500 m7g. The nano fibers are ...
