The invention is directed to a process and equipment for use in a process to bacterially decompose organic waste to a dry composted end material wherein organic waste is composted in a composting tank in the presence of oxygen and aerobic bacteria to obtain a wet composted material. The wet composted material is partly removed from the composting tank and dried such to lower the water content of the composted material to obtain dry composted end material.

A fluid acceleration system includes a housing, a rotational element, a conduit assembly, and a driver. The housing defines an inlet, an outlet, and an interior chamber configured to receive a fluid. The rotational element is disposed within the interior chamber. The rotational element includes a central support and a plurality of blades coupled to the central support. The central support extends between an upper wall and a lower wall of the housing. The conduit assembly is positioned external to the housing. The conduit assembly connects the outlet to the inlet. The driver is positioned to drive the rotational element to accelerate the fluid within the interior chamber such that a portion of the fluid flows out of the outlet, through the conduit assembly, and back into the interior chamber through the inlet.

A mixer apparatus for mixing a high-viscosity fluid has a mixer shaft with a plurality of blades affixed thereto, a hydraulic motor drivingly connected to the mixer shaft so as to rotate the mixer shaft, a hydraulic pump connected by a fluid circuit to the hydraulic motor so as to deliver hydraulic fluid under pressure to the hydraulic motor, an electric motor drivingly connected to the hydraulic pump, and a hydraulic fluid reservoir connected to the fluid circuit so as to supply hydraulic fluid to the hydraulic pump. The plurality of blades are pivotally mounted to the mixer shaft.

There is provided methods and systems for disaggregation and deagglomeration of small scale materials such as carbon nanotubes by cavitation of a treatment substance. The treatment substance may be a substance such as CO.sub.2 which is capable of undergoing phase changes. Systems must be capable of withstanding high pressures, and cavitation may be done by ultrasound, mechanical agitation, injection of a jet stream, or other methods. Materials treated via the methods of the invention may be removed without the use of chemical surfactants or other chemical modification means, and may be further used in a battery.

A carbonator reactor includes a cylindrical body, a nozzle for supplying a gas stream, inside the carbonator reactor and above the surface of a liquid phase and where the nozzle is located at the top of the reactor body, an inlet, an outlet, means for regulating the temperature and the pressure, a stirring system and at least one baffle regulating the stirring of the liquid phase and the mass transfer of the gas into the liquid surface, at least one impeller having inclined blades that make an angle from 5° to 60° with respect to the vertical axis. The reactor prepares sodium carbonate and has a configuration for the mass transfer of a gas phase in a liquid phase. A method for the preparation of sodium carbonate by means of the carbonator reactor by capturing CO.sub.2 in an NaOH aqueous solution, directly on the free surface of the liquid phase.
