Automatic Backwash Multimedia Filters for Sediment Removal with Pentair Fleck Valves

Multi-Media Filtration is effective in removing dirt, silt, rust, and other suspended particles from a water stream with a filtration level of approximately 5 to 15 microns.

Multi-Media Filters contain several types of media and gravel under bedding. Multi-media filtration is a proven design concept; the coarse media layers in the top of the tank trap large particles, and successively smaller particles are trapped in the finer layers of media deeper in the bed The result is a highly efficient filtering since removal takes place throughout the entire bed. Multi-Media depth filters typically remove particles 5-15 microns in size or larger. All media included in our filters are carefully selected according to particle size, so the media retains its stratification during backwash and rinse. Automatic backwashing system removes the trapped contaminants within the filter bed and washes them down the drain.

  • Protect downstream equipment and appliances
  • Removes Suspended Solids from Water to Approximately 5 to 15 Microns
  • Highly Efficient and High Capacity Filtration
  • Automatic Backwash Feature Reduces Maintenance, Maintains Filter Efficiency, and Prolongs the Life of the Filtration Media

Ordering Notes:

* Multi-media Backwash Filters are available with several options of valve voltages. Please add the appropriate voltage code to the end of the model when ordering.
110v/60Hz = 116 Example: W-MB744-116
220v/60Hz = 216 Example: W-MB744-216
220v/50Hz = 215 Example: W-MB744-215

**5 gpm per sq. ft. of media is the best design condition for filtration. For relatively clean water, you may go up to design criteria of 15 gpm per sq. ft. Backwash flow rate based on 25 psi pressure drop.

Skid mounting, control panel and custom sizes and configurations are available upon request.
