Filtration

The rate of flow on a filter depends on the type of filter. A rapid sand filter will have a flow of 23 gpm/square foot of filter area. The high rate filter may have 46 gpm/square foot applied to the surface. A constant rate flow valve is almost fully closed when a filter is clean so that the desired water level on top of the filter is maintained.

Silica dust | Cancer Council

Silica dust (crystalline silica) is found in some stone, rock, sand, gravel and clay. The most common form is quartz. Silica dust can also be found in the following products: bricks; tiles; concrete; some plastic material. When these materials are worked on, silica is released as a fine dust known as respirable crystalline silica or silica dust.
