Importance of Water Filtration

Water filtration is necessary to clean dirty or murky water for human

consumption. This is an important part of human society and

infrastructure, but is especially important in the 3rd world and

developing countries  

Objective

Design and build a dual media water filter cell capable of

removing turbidity from two gallons of muddy water

Design

Washed Sand

Layer of Coffee Filters

Washed Charcoal

Coarse Aggregate

Mesh

~1in

~5in

~5in

Materials Used

Garden Liner Mesh

Coarse Aggregate

Lowe's Bucket

Sand

Crushed Charcoal

Coffee Filters

Procedure

1.Drilled holes in the bottom of the bucket2.Lined bottom with garden liner mesh3.Thoroughly washed coarse aggregate,

charcoal, and sand4.Added about 5 inches of washed coarse

aggregate, topped with coffee filters5.Added about 5 inches of washed charcoal,

topped with coffee filters6.Added about 1 inch of washed sand on top

Final Product

The filter cell is positioned above an empty bucket, which is used as a

clear well. The muddy water is then poured above the filter cell.

Test Run DataFlow Rate:

Trial #1: 0.148 gpmTrial #2: 0.240 gpmTrial #3: 0.210 gpm

Average: 0.199 gpm

Turbidity:Initial Turbidity 2805 ntu

After Test 13.4 ntu

Conclusion

Given that the filter cell operates at an average output flow rate of 0.2 gpm, the 2 gallons of muddy water should take approximately 10

minutes to pass through the filter. The filter is expected to eliminate at least 70 percent of the

turbidity from the muddy water sample. Our Sample came out to 99.5 percent of the

turbidity.
