An aerobic composting system and method utilizes circulation of a gas through a mixture of liquid and organic materials to continuously mix the liquid and organic materials while encouraging aerobic organisms which aid with the composting process. The aerobic composting system generally includes a container which is adapted to store a volume of a liquid to be continuously mixed with organic materials to produce compost. The container may include a first opening through which the liquid and/or organic materials are introduced into a cavity of the container. The container may also include a second opening such as a spigot through which the resulting compost is dispensed. A gas dispenser is positioned on the floor of the container within the cavity to continuously dispense a gas through the liquid so as to mix the organic materials with the liquid and to encourage aerobic organisms which aid with the composting process.

The present disclosure relates to a continuous fermentation device that can ferment objects continuously fed thereinto while conveying the objects. The present disclosure provides a continuous fermentation device comprising a plurality of fermentation modules, each including: a conveyor belt, which transports objects that are continuously fed thereinto to be fermented from one side to the opposite side thereof; agitators, which is located on the conveyor belt; and an air diffuser, which is located on one side of the conveyor belt, in which the continuously fed objects to be fermented are fermented while being passed through the fermentation modules. According to the present disclosure, feeding of raw materials to be fermented, fermenting the raw materials, and discharging of the fermented materials are continuously performed so that it is possible to significantly reduce the processing time, thereby reducing the operation time of the production process. Accordingly, it is possible to achieve an increase in competitiveness, such as improved productivity, reduction of investment cost, etc., in the development of a method of mass production through solid-state fermentation, thereby innovatively reducing the production cost of the product.

The systems and methods disclosed herein provide for the efficient generation of fine bubbles. In particular, systems and methods for use in bioreactors are disclosed herein providing a superior means to produce useful fermentation products by the biological fermentation of fine bubble waste substrates injected into a liquid broth containing a microorganism culture.

A washing machine according to the present invention comprises: a cabinet which forms an outer shape; a tub which is disposed inside of the cabinet, and in which washing water is stored; a pump which circulates the washing water stored in the tub; a circulating nozzle which sprays, into the inside of the tub, the washing water supplied from the pump; a circulating hose which connects the pump to the tub, and guides the circulated washing water to the circulating nozzle; and an atomizing unit which is disposed on the circulating hose, and atomizes the circulated washing water by mixing air. The washing machine according to the present invention supplies, into the inside of the tub through an air mixer, washing water in which air is included, and thus has an advantage of reducing the total flow rate of the used washing water.

A diffuser is disclosed and includes a channel with an inner portion having an inlet and an outlet through which a gaseous substance enters and exits the diffuser, respectively. The inner portion includes a first conical section that has an increasing cross-sectional area, taken along a plane perpendicular to a central axis, in a first direction. The inner portion also includes a second conical section that has a decreasing cross-sectional area, taken along a plane perpendicular to the central axis, in the first direction. The second conical section is communicatively coupled with the first conical section. The outer portion includes a first annular section that has an increasing cross-sectional area, taken along a plane perpendicular to the central axis, in a second direction opposite the first direction. The diffuser further includes a plurality of orifices that communicatively couple the second conical section with the first annular section.

An automated frothing assembly. The automated frothing assembly has a wand module that includes an elongate member having an inlet, one or more outlets, and a fluid passageway extending between and in fluid communication with the inlet and the plurality of outlets. At least one of the one or more outlets extends parallel to a vertical plane that includes the centerline of the elongate member and at an acute angle relative to a horizontal plane that is perpendicular to both the vertical plane and the centerline of the elongate member. The assembly further includes an actuator configured to be operatively coupled to the wand module and to drive the movement of at least a portion of the wand module along an axis, and an electronic controller configured to be electrically coupled to the actuator and to control the operation of the actuator to control the movement of the wand module.

The present disclosure relates to a poly-ionic and molecular filtering and diffuser device, which provides for the emission of gases when used from the inside out, and a separation of suspended matter (e.g., in macro, micro and nano ranges) in liquids for a variety of fluids when is used from the outside inwards. The device may include a central diffuser tube defining a plurality of perforations in its wall to allow passage of gas and liquids, and which is inserted through central holes of a plurality of plates diffusers arranged in a vertical arrangement. This combination may define a plurality of slots by the separations generated therebetween, whereby the gas or the liquid is spread. The diffuser-separating plates are contained between a top compression cap and a lower compression cap through which said central diffuser-collector tube is also inserted. The central diffuser-collector tube includes a threaded lower end, wherein a final lower lid is threaded. Seal elements may be disposed between the upper and lower compression cap and the arrangement of the plurality of diffuser-separating plates.

The present disclosure relates to a device for producing microbubble water by using a ultrasonic vibrator having a maximized amount of dissolved bubbles, a microbubble discharge unit, cell culture medium containing microbubble water and cell culturing method using the same, a high-efficiency mixed fuel using microbubble and apparatus for manufacturing the same.

The systems and methods disclosed herein provide for the efficient generation of fine bubbles. In particular, systems and methods for use in bioreactors are disclosed herein providing a superior means to produce useful fermentation products by the biological fermentation of fine bubble waste substrates injected into a liquid broth containing a microorganism culture.

An air diffuser includes: a bottom panel provided in a horizontal direction in a tank in which water is filled; an air diffusion body installed to cover the bottom panel from above; and air diffusion holes arranged to penetrate through the air diffusion body, gas fed to a gap between the bottom panel and the air diffusion body is discharged into water through the air diffusion holes, and an air diffusion region of the air diffusion body where the air diffusion holes are arranged has a width equal to or larger than 10 mm and smaller than 120 mm. A method of treating water using the air diffuser includes supplying air to the air diffuser at a volume of equal to or smaller than 60 [Nm.sup.3/(m.sup.2.Math.hr)].
