Multi-Media Filters (Sand Filters) with Automatic Backwash for Sediment Removal
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.
Benefits of Multi Media Backwash Sand Filters for Sediment Removal
- 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 Sediment Filters are available with USA or European style plugs and voltages. Please add the appropriate voltage code to the end of the model when ordering.
- 120V AC/60Hz with USA cord = US
- Example: W-MB744ET-US
- European 220V AC = EU (EU plug is removable to convert into universal 220v cord)
- 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. AMI Auto Backwash Multi-Media Sand Filters Filters are offered standard with new state of the art electronic programmable valves, but may be ordered with electromechanical Fleck valve heads upon request.
