Clack Filter-Ag® has many outstanding advantages over the
more common granular filter media 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 through out the
filter bed, typically reducing suspended solids down to the
20-40 micron range. The 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
build up of head loss 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.
Although not intended to be an iron reduction media,
extensive field experience has shown Filter-Ag®’s rough and
jagged surface to be very good at entrapping the fragile
iron flock that forms after dissolved iron has been oxidized.
The fragmented edges are apparently good flock collection
points for the precipitated iron. Typical oxidation methods
include aeration, ozonation and chlorination.
Substantial savings can be realized when designing a system
using Clack Filter-Ag®. Its low pressure drop, high service
flow rates and high bed loadings combined with lower
backwash rates allow economy in equipment downsizing
and reduced pumping requirements. Its light apparent
density also saves on handling expense and shipping costs.
Filter-Ag® can be applied to systems designed for either
pressure or gravity flow. Because of its unique density,
Filter-Ag® can also be used in multi-media (graded density)
filter designs allowing a more flexible approach to difficult
There is less pressure loss through a bed of Filter-Ag® than
through most other fi lter media
Light weight requires lower back-wash rates than those
required for other fi lter media
High service rates result in lower equipment costs and a
savings in space
High sediment reduction capacity results in longer fi lter
runs, with a substantial savings in backwash water and
time out of service
Reduced shipping cost due to light weight/cu. ft.
Replacement of sand with Filter-Ag® in existing installations
may increase fi lter capacity 100% or more. Caution
should be taken upon start-up that the lightweight Filter-
Ag® is not washed to drain
