Both types are compression crushers. Although economical, they have the tendency to

Wastewater Technology Fact Sheet: Wetlands: Subsurface Flow

flow (SF) wetland is specifically designed for the treatment or polishing of some type of wastewater and are typically constructed as a bed or channel containing appropriate media. An example of a SF wetland is shown in Figure 1. Coarse rock, gravel, sand and other soils have all been used, but a gravel medium is most common in the U.S. and Europe.

Section III: Surface Gravel US EPA

Gravel is a mixture of three sizes or types of material: stone, sand and fines. This will be discussed further in the next section.Without a good blend of these three sizes, the gravel will perform poorly. Unfortunately, poor performing gravel will often be blamed on the maintenance operator. But the operator cannot make good gravel out of bad gravel.
