Attorney, Agent or FirmInternational ClassB01F 005/06AbstractAn apparatus and method for treating effluents is disclosed for selective solids control and/or dewatering of effluents, for example drilling fluids (or mud), slurries or sludges, or other clean up involving solids removal from a hydraulic system where flocculation would be employed. The apparatus is compact and portable for ease of on-site delivery and hookup and includes a plurality of mixers for mixing polymer materials with water and/or the effluent, a plurality of pumps for controlling the flow of effluents, water and mixed liquids, and a plurality of conveniently located valves and pump controls for control of the various functions of the apparatus from a centrally located control panel. An improved mixing device is provided for blending of shear-sensitive fluids which includes multi-port injection sites and a series of geometrical flow altering elements. A device for wetting dry particulate material in a liquid feed stream is provided having a cylindrical funnel eductor and a cyclonic dispersal eductor.Field of SearchSTATIONARY DEFLECTOR (DIVIDING AND RECOMBINING TYPE) IN FLOW-THROUGH MIXING CHAMBERAngularly related flat surfaces Curved deflector surface Helical ribbon or strand Plate or block being apertured, notched, or truncated in shape STATIONARY MIXING CHAMBER Means to cause rotational flow of fluid (e.g., vortex generator) Vortex generator in interaction chamber of device WITH FLOW REGULATORS AND/OR BAFFLES JOINED SECTIONS SERIALLY CONNECTED DISTINCT TREATING WITH OR WITHOUT STORAGE UNITS Separating | |
