The slow sand filtration alternative – Water treatment for ...

May 01, 2000  Conventional slow sand filtration. The traditional slow sand filter is basically a box full of sand. Figure 1.1 shows a cross section of a ‘conventional’ filter. Water enters the filter compartment above the media and flows down through the sand and, in time, will form a thin biological layer called a schmutzdecke.

Soil Improvement Techniques - IJSER

Fig. 2. Sand drains (after, Das 1983) Sand drains can work as sand piles. They reinforce soft soil in which they are installed. Even though sand drains replace only 1 to 2% of soil volume, the overall improvement in bearing capacity may be more than 10 % [6] But on the other hand, they have some disadvantages:

Sand Filter - an overview ScienceDirect Topics

The homogeneous sand filter has a 0.9–1 m deep bed of typically 0.85–1.7 mm sand (d 10 =0.9 mm) placed on a 50 mm layer of 4–8 mm or 75 mm of 6.7–13.2 mm gravel. Homogeneous sand of effective size up to 1.3 mm has also been used. The stated size ranges for sand and gravel are generally 5 and 95 percentiles.
