Tangential sand catcher
Tangential sand catcher

Tangential sand catcher. It is a plant of mechanical wastewater treatment meant to remove coarsely dispersed suspended solids. The operation principle of the tangential sand catcher is based on the separation of discharge liquid and coarsely dispersed suspended solids under the influence of centrifugal and gravitational forces.

Sand Grains from Around the World! - Geology

When oil and gas wells are drilled into tight formations, the production zone is fractured by ,pumping, a high-viscosity liquid down the well. The liquid is pumped at a pressure that exceeds the breaking point of the rock. When the rock fractures, the liquid and billions of ,suspended sand, grains rush into the fractures.

Smaller ,sand, grains provide more surface area and therefore a higher decontamination of the inlet water, but it also requires more ,pumping, energy to drive the fluid through the bed. A compromise is that most rapid pressure ,sand, bed filters use grains in the range 0.6 to 1.2 mm although for specialist applications other sizes may be specified.

Filter material is separated from the waste water containing suspended solids by the separator at the top of the filter vessel before reversing direction, precipitating inside the sand washer, and returning to the layer surface. When passing through the sand washer, the sand is washed a final time by some of the upward-moving filtered water.

Turning Sand Into a Fluid – FYFD
Turning Sand Into a Fluid – FYFD

With a high flow rate, the space between sand grains gets larger, eventually reaching a point where the aerodynamic forces on a grain of sand equal gravitational forces. At this point the sand grains are essentially suspended in the air flow and behave like a fluid themselves.
