A separation system and method, of which the system includes a separation device comprising a mixed fluid inlet, a first outlet, and a second outlet, a tank coupled to the second outlet and configured to receive a solid from the separation device via the second outlet, and a solids-level sensor extending through the tank and positioned at an elevation above a bottom of the tank. The solids-level sensor is configured to detect a viscosity of a material within the tank at the elevation.

A mobile water treatment system and method, of which the system includes a bioreactor including an aerator tank configured to receive an influent fluid, a conical clarifier positioned in the aerator tank, the conical clarifier defining a downwardly-facing opening. An interior of the conical clarifier is in communication with the aerator tank, external to the conical clarifier, via the downwardly-facing opening. The bioreactor also includes a plurality of aeration vents positioned proximal to a bottom of the tank and configured to direct air into the aerator tank, but not toward a bottom of the conical clarifier, and an effluent outlet positioned in the conical clarifier. A relatively clean effluent fluid, in comparison to the influent fluid in the aerator tank, exits from the conical clarifier via the effluent outlet.

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.

A glycerin separation system heats a mixture of glycerin to about 231 degrees Fahrenheit and then allows the mixture to rest in a settling tank. Over time the mixture separates into layers of differing densities. The layers are removed individually by measuring the density of the exiting fluid. The glycerin is heating in a loop to allow for precise control of the temperature of the mixture. The pH is also controlled with a preferable level of 5.

An arrangement and a method for controlling a dewatering process including measuring values representing operating parameters of the gravitational sedimentation device and using the values as input values for a predictive multivariable model for predicting an operating state of the gravitational sedimentation device. The disclosure further relates to obtaining reference values for the operating parameters, determining at least one predicted output for an operating parameter of the gravitational sedimentation device, and comparing the predicted output to at the reference values to determine control values that will affect changes in operation of the gravitational sedimentation device.

Introduced here are systems for treating a wastewater stream to produce an effluent stream. A treatment system can include a sensor for measuring a characteristic of the wastewater stream and/or the effluent stream, a pump for supplying a chemical additive to the wastewater stream, and a controller for varying the flow rate of the chemical additive based on real-time analysis of measurements generated by the sensor. The characteristic could be, for example, turbidity, pH, total suspended solids (TSS), etc. Some embodiments of the treatment system further include a flow meter for measuring flow of the wastewater stream. In such embodiments, the controller may vary the flow rate of the chemical additive based on the measurements generated by the sensor and the flow meter.
