FILTRATION MEDIA : FILTER-LITE

GENERAL DESCRIPTION

Filter-Lite granules have irregular surface characteristics affording maximum removal of suspended matter throughout the filter bed. Filter-Lite can be applied to systems designed for either pressure or gravity flow.

Filter-Lite has many outstanding advantages over the more common granular filter medias used for suspended solids removal. Substantial savings can be realized, when designing a system using Filter-Lite, because equipment can be smaller, requiring less square foot area. Filter-Ag is a lightweight substance, which means additional savings in backwash rates. Filter-Lite typically removes the normal suspended solids, down to the 20-40 micron range.
 

Physical Properties:
Color	Light Grey
Density	24 - 26 lbs./cu. ft.
Effective Size	0.57 mm
Uniformity Coefficient	1.66

 

Conditions For Operation:
Max. Temperature	140° F (60° C)
Bed Depth	24 - 36 in.
Backwash Rate	8 - 10 gpm/sq. ft.
Backwash Expansion Rate	35 - 50% of bed depth
Service Flow	5 gpm/sq. ft., although considerably higher rates are often used

 

Advantages:

There is less pressure loss though a bed of Filter-Ag than most other filter medias.

Light weight requires lower backwash rates than those required for other filter media.

High service rates result in lower equipment costs and a savings in space.

High dirt removal capacity results in longer filter run, with a substantial savings in labor costs, backwash water and time out service.
