Sand treatment systems and methods

A method for treating a stream, the stream including liquid, and the stream flowable, the stream having material therein, the material comprising first material and second material, the first material comprising particles of a first size with a first largest dimension, and the second material comprising particles of a second size with a second a second largest dimension, the first largest dimension being smaller than the second largest dimension,

• the method comprising
• flowing the stream to a system, the system Including a tube, the tube having an interior surface, the tube having a first end and a second end, the tube inclined with the first end higher than the second end so that the stream is flowable through the tube from the first end to the second end and out from the second end aided by gravity,
• jetting water into the stream within the tube, the jetted water moving the stream around within the tube to facilitate working of the materials of the stream within the tube, and
• inhibiting with the jetting water the stream from flowing aided by gravity,
• said inhibiting maintaining the stream within the tube for a period of time to prolong working of the material within the tube.

• the method comprising
• flowing the stream to a system, the system Including a tube and screening apparatus,
• jetting water into the tube to work the material in the stream within the tube producing an intermediate stream with the material and Jetting water,
• flowing the Intermediate stream to the screening apparatus,
• separating, with the screening apparatus, the first material from the second material, the second material unable to pass through the screening apparatus and the first material passing through the screening apparatus.

• wherein the screening apparatus comprises a screen, the screen having a top higher than a bottom thereof and curved Inwardly from top to bottom with a curved surface down which the Intermediate stream is flowable,
• the method further comprising flowing the intermediate stream to the top of the screen to separate out the first material from the intermediate stream,
• wherein the screen has screening material on a base, the base has a plurality of spaced-apart holes though which are passable the first material separated out from the intermediate stream by the screen, the holes disposed substantially vertically,
• the method further comprising
• flowing first material through the holes and down from the screen,
• wherein the screen has a top screening material surface and each hole has an opening at said top screening material surface, each opening comprising an elongated opening with a length larger than a width thereof, each said opening In fluid communication with a corresponding hole, said elongated openings configured to facilitate passage through the screen of first material,
• the method further comprising
• flowing the intermediate stream down the curved surface of the screen to the openings,
• wherein the system further comprises water application apparatus for applying water on the screen apparatus,
• the method further comprising
• applying water on the screen apparatus into material flowing down the screen,
• the application of the water inhibiting downwardly flow of material down the screen and prolonging the material on the screen apparatus for a period of time.
