Abstract
Systems and methods for dewatering drilling fluid including a feeder, an aging tank, a polyductor configured between the feeder and the aging tank and a flocculant solution pump fluidly connected to the aging tank. Further, the system includes a portable skid to house the feeder, the aging tank, the polyductor, and the flocculant solution pump. In certain embodiments, the polyductor is configured to mix a liquid with a dry flocculant from the feeder, and disperse a resultant flocculant solution in the aging tank, the aging tank is configured to receive the flocculant solution, and the flocculant solution pump is configured to remove the flocculant solution from the aging tank.
