A means to exploit the Dean Vortices for dynamic filtering on a macro scale intended for application in utility and industrial processes is disclosed. This method relies on an apparatus of computed construction to optimize the centripetal force and minimize the effect of gravity on the separation and effectiveness of the Dean Vortices. The method is also supported by an apparatus of construction which results in an optimized elliptical flow channel that enhances the formation and persistence of the Dean Vortices.

The present disclosure provides apparatus, systems, and methods for improving slop water treatment efficiency. The method generally includes separating contaminated fluid into a clean fluid layer and one or more contaminant layers floating on a surface of the clean fluid layer in a vessel; reporting to a control unit, a location, sensed by level sensor(s), of an interface between the clean fluid layer and the contaminant layer(s); reporting to the control unit, a height, sensed by a first position sensor, of a skimmer relative to the vessel; adjusting, using the control unit and based on the reported location of the interface and/or the reported height of the skimmer, the height of the skimmer so that one or more components of the skimmer are positioned proximate the sensed location of the interface; and skimming, using the skimmer, the contaminant layer(s) off of the clean fluid layer proximate the sensed interface.

An apparatus for separating cell suspension material into centrate and concentrate, includes a single use structure (178, 240, 250) releasably positioned in a cavity in a solid wall rotatable centrifuge bowl (172). The bowl and portions of single use structure rotate about an axis (174). A stationary inlet feed tube (184), a centrate discharge tube (212) and a concentrate discharge tube (230) extend along the axis of the rotating single use structure. A centrate centripetal pump (208) is in fluid connection with the centrate discharge tube. A concentrate centripetal pump (216) is in fluid connection with the concentrate discharge tube. A controller (274) operates responsive to sensors (264, 270) in respective centrate and concentrate discharge lines (262, 268), to control flow rates of a concentrate pump (272) and a centrate pump (266) to produce output flows of cell concentrate and generally cell free centrate.

A machine and methods using electro-chemical treatments, sedimentation processes and dissolved air flotation technologies for clarification of several kind of wastewater produced in industries, sewages, ponds, lakes, canals etc. The machine comprises of, feeding lines with multiple feeding point, a tank and further a collection tank. The wastewater is passed into the feeding line which may comprises of several feeding points for coagulants, flocculants, and other chemicals dosing into the flow of wastewater and may also comprises of a static mixer for mixing the coagulants, flocculants, and other chemicals with wastewater to agglomerate any solid particles and to accelerate separation of the solid particles in the tank. Once the solid are formed, they can go up or down, therefore to remove the suspended solids the outlet are rearranged depending on the suspended solids. Further, the machine is used for treatment of wastewater utilising multi pass concept to produce clean water.

Systems and methods for processing one or more waste fluids by measuring one or more properties of a waste fluid and adjusting the flow and/or flowability of the waste fluid based on the measurement are disclosed. The one or more properties of the waste fluid can include a viscosity of the waste fluid, a pressure of the waste fluid, and/or or a difference in pressure of the waste fluid. Adjusting the flow and/or flowability of the waste fluid can include adjusting the one or more properties of the waste fluid and/or affecting the direction of flow of the waste fluid in a manner which changes the destination of the waste fluid.
