Filter-Ag

Request a Quote Ask a Question

Filter-Ag is a non-hydrous silicon dioxide media which can be used as highly efficient filter media for the reduction of suspended matter.

 Filter-Ag has many outstanding advantages over the more common granular filter medias used for suspended solids reduction. Its fractured edges and irregular surface provides a high surface area and complex flow path for efficient removal of suspended matter throughout the filter bed, typically reducing suspended solids down to the 20-40 micron range.

Filter-Ag's larger particle size creates less pressure loss through the filter and allows deeper sediment penetration into the bed for higher sediment loading and longer filter runs. This large and irregular shape prevents the screening and caking of sediment in the top several inches of the filter bed as happens in the typical sand filter, thus preventing a rapid buildup of headloss and blinding problems.

Filter-Ag's light weight means lower backwash rates and better bed expansion to release trapped sediment and rinse the filter media during the backwash cycle. This ideal combination of particle shape, size and density make it a good choice where quality water filtration and water conservation are important.

Ordering Notes:

* Filter-Ag Sediment 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-MA744-116
220v/60Hz = 216 Example: W-MA744-216
220v/50Hz = 215 Example: W-MA744-215

**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.
