Filter Sand

Sand filtration continues to make good sense: its cost-to-benefit ratio is very high, and effluent water quality is often very good. Sand systems can filter to a 10 micron level, yet they are simple in design and operation. River washed .44 to .55 mm sand with a high silica content, low impurities and a highly spherical shape for municipal, industrial and residential filter applications.

FILTER SAND is graded specifically for use at water filtration plants. It can be used in municipal, industrial or residential applications.

The highly spherical shape of UNCRUSHED GRAVEL promotes good flow and even distribution. Being low in soluble impurities, it will maintain the quality of the treated water, especially in softeners. Three inch layers are recommended in graded support beds.

Conditions for Operation (Filter Sand):
Bed Depth: 18 - 30 in.
Backwash Rate: 15 - 20 gpm./sq. ft.
Backwash Bed Expansion: 35% of bed depth
Service Flow Rate Municipal: 1.5 - 2 gpm/sq. ft.
Industrial: 3 gpm/sq. ft.
Domestic: 5 gpm/sq. ft.

Advantages:

• Highly-spherical shape and uniform grading provides reliable performance in this product with a long history of performance.
• Low soluble impurities prevent undesirable mineral leaching into process stream.
