Abstract: A method and apparatus for recycling drilling fluids used in the drilling of wells is provided. The apparatus comprises a tank with a plurality of compartments. Used drilling fluid containing well cuttings or “solids” is pumped into a receiving compartment of the tank and directed towards a flow-reversing barrier. Reversal of the flow causes heavier solids to settle to the bottom of the tank. As fluid fills the receiving compartment, it flows downstream into an adjacent compartment by passing through a flow-restricting baffle that causes more solids to settle to the bottom of the tank. As fluid overflows from compartment to compartment in the tank, it passes through successive flow-restricting baffles causing further solids to settle to the bottom of the tank. Fluid is removed from the collecting compartment of the tank to be used again in drilling operations.

Abstract: A dust-control apparatus may be used in combination with tilling, cultivating, harvesting, construction machinery, and other mobile soil treatment implements. The apparatus applies mist to dust particles where the mist is created by pumping water or other liquid through nozzles.
