Self-indexing filters are a non-pressurized method to separate solids from process fluids. The units have a distribution header to slow the incoming fluid stream and distribute it across the filter media. The media is held between two rollers, suspended over a tank for holding the filtered water. As the incoming fluids are discharged over the filter, the solids are captured on the media while the filtered water passes through. As the filtered water reaches a certain level, the filter media is indexed by the rollers, discharging the fouled media and introducing a new section.
Self-indexing filters are available in a variety of sizes, depending on the flow rate of fluid to be treated. A number of different weights of filter media are also available to capture different types and sizes of solids.
Considerations when selecting a self-indexing filter include fluid flow rate, type and level of contamination and the space available for the filter.
MLE Equipment uses Filter Innovations’ line of self-indexing filters. Please see the provided specification sheets and manuals for more detailed information on self-indexing filters.
