Systems for manufacturing filter media incorporating nanoparticles

Abstract

Systems, devices and methods are provided for producing a product comprising a filter media, such as a gas or liquid filter. A system comprises a feeder for advancing a substrate comprising fibers from an upstream end to a downstream end and a dispersion device for dispersing nanoparticles into the substrate as the substrate is advanced by the feeder to form the filter media. The system further comprises a container for receiving clusters of nanoparticles and a feed system for conveying the clusters of nanoparticles from the container to the dispersion device. The feed system is particularly useful for introducing nanoparticles into a continuous manufacturing process at a controlled flow rate. The system both conveys and elevates the nanoparticles and allows for the manufacture of filter media with improved quality and yield and reduced cost and time. In addition, the system is scalable and produces filter media with less variation.
