Abstract: Dehydrator systems having a core dehydrator and a mixing unit are described herein and methods of using the same. The core dehydrator comprises a turbulent flow mixing compartment the turbulent flow mixing compartment with plate openings having a turbulent flow transition zone where linear speed of fluid flow is reduced, a clarifying sediment chamber, where fluid flow is substantially laminar) comprising a plurality of small deflector plaques and a plurality of large deflector plaques and a flocculation pipe. In the turbulent flow transition zone, fluid flow transitions from turbulent flow to laminar flow. The mixing unit comprises a plurality of vertical flocculators. The mixing unit further comprises a rapid mixing manifold. The rapid mixing manifold contains drilling fluids and flocculant polymers.
