Method and system to separate solids from liquids
First Claim
1. A system to separate solids from liquids in a fluid, the system comprising:
- at least one tank;
a plurality of alternating baffles disposed along a length of the tank configured to define a vertical tortuous flow path of the fluid along the length of the tank from a first end of the tank to a second end of the tank to cause solids to settle out of the fluid, and each alternating baffle having a sloped planar surface disposed between a lower horizontal planar surface and an upper horizontal planar surface to cause at least one eddy in a vertical plane as the fluid flows through the tank;
an inlet to the tank located at the first end of the tank;
an outlet to the tank located at the second of the tank; and
a solids sump located proximate a bottom portion of the tank, wherein the sump is configured to collect the solids from the tank.

Abstract
A system to separate solids from liquids is disclosed. In a particular embodiment, the system includes a series of alternating baffles disposed along a length of a tank, where the series of alternating baffles define a vertical tortuous flow path of the fluid from a first end of the tank to a second end of the tank to cause solids to settle out of the fluid. The alternating baffles each have a sloped planar surface disposed between a lower horizontal planar surface and an upper horizontal planar surface to cause at least one eddy in a vertical plane as the fluid flows through the tank. The system may also include a series of tanks in fluid communication with the at least one tank and secured side by side, where the solids progressively settle out from the fluid in stages as the fluid passes from one tank to another in series.

7. A method to separate solids from liquids in a fluid, the method comprising:
-
pumping fluid with suspended solids to at least one tank; and using a plurality of alternating baffles disposed along a length of the tank to define a vertical tortuous flow path of the fluid along the length of the tank from a first end of the tank to a second end of the tank to cause solids to settle out of the fluid, and each of the alternating baffles having a sloped planar surface disposed between a lower horizontal planar surface and an upper horizontal planar surface to generate a plurality of eddies in a vertical plane as the fluid flows through the at least one tank. - View Dependent Claims (8, 9, 10, 11)
