A mixing assembly includes a main flow conduit having an inlet end and an opposite outlet, a source of pressurized air at the inlet end, a container of stucco in fluid communication with the flow conduit, and a source of water in fluid communication with the flow conduit between the outlet and the container. The pressurized air draws stucco from the container into the flow conduit, and also draws water into the flow conduit to form an atomized slurry.

An improved particulate metering system is provided. The system includes a flow path having an inlet in communication with an intake and an outlet in communication with a discharge. The flow path receives a first input and a plurality of inputs, each of the plurality of inputs having a separate origin. A mixing area within the flow path comprises a confluence of the first input and one or more of the plurality of inputs. One or more metering controls are in operable communication with the first input and the plurality of inputs for controlling a blend of the plurality of inputs at the confluence.

An ozone supply device is described for generating ozone and supplying the ozone to a livestock feed system for application to livestock feed to sanitize the feed. The device includes an intake port for receiving air from outside the device, an ozone generator for receiving air from the intake port and converting oxygen in the air to ozone, an ozone compressor intake for receiving ozone produced by the ozone generator, a compressor pump for compressing ozone received through the ozone compressor intake, and an ozone supply line for transmitting compressed ozone to a livestock feed system for application to the livestock feed. The device also includes an ozone meter and display, a timer, an inverter, and one or more housings. An adapter is interconnectable between the livestock feed system and the ozone supply line of the ozone supply device to connect them together.

An apparatus for treating organic mass. The apparatus comprises a treatment chamber and agitation means provided in the chamber to agitate the organic mass. The agitation means comprises a rotatable shaft extending through the chamber, a plurality of agitator arms extending from the shaft, and a paddle connected to each agitator arm. The paddle is arranged to make a first angle with respect to the longitudinal axis of the agitator arm and a second angle with respect to the longitudinal axis of the shaft. There is also provided a system for recycling ammonia generated from the treated organic mass by the apparatus.

An apparatus including an air blower; a rotary airlock; a receptacle having an inner chamber supplied with a plurality of colorant particles; a water supply; and a mixing chamber. The air blower blows air into a bottom section of the rotary airlock, and the rotary airlock receives colorant particles from an output of the receptacle. A rotor shaft of the rotary airlock rotates to cause colorant particles to be transported to the bottom section of the rotary airlock. Air blown into the bottom section of the rotary airlock mixes with colorant particles transported into the bottom section of the rotary airlock to form an air and colorant particles mixture, which is blown out of a first output of the rotary airlock and combined with water to form a water, air, and colorant particles mixture, which is mixed with material in a mixing chamber. The material may be natural mulch.

In one aspect, the present disclosure involves a re-aeration device and re-aeration method for constructed wetland. In one aspect, the re-aeration device comprises a re-aeration pipe and a windmill. The re-aeration pipe has a tubular structure with openings at both ends; one end inserts into the wetland substrate, and the other end connects with the windmill for receiving and accelerating air flow. The re-aeration pipe may also contain several telescoped or parallel arranged pipes with openings at both ends as well as with different pipe diameters and lengths, which connect with the windmill to form the re-aeration device. The present disclosure also provides a method of re-aeration for constructed wetlands by using the above-mentioned device. The re-aeration device provided herein has features of being simple in structure, environment friendly, and low-cost. In one aspect, the re-aeration method is characterized as simple, practicable, energy-efficient, environment friendly, low-cost, widely applicable, and having good effect and high performance on re-aeration.
