A water treatment system for aeration of water in a treatment tank includes at least one bridge extending above an upper surface of the water in the tank; a retrievable mounting frame assembly, including a frame, a plurality of aeration elements, a plurality of mounting brackets to secure the aeration elements to the frame, a control arm having secured to the frame at the first end, and a first air distribution conduit coupled to the aeration elements for supplying an air flow to the aeration elements; at least one guide rail system secured to the bridge assembly and extending to the floor of the tank, the guide rail system having at least one or multiple parallel guide rails, a second air distribution conduit coupled to the first air distribution conduit, and an actuatable push-rod positioned between the guide rails and connected to the control arm's second end. The hold-down rod, when actuated, moves the mounting frame assembly along the guide rails from a first position above the upper surface of the water and into a second position on the floor of the tank for aeration of the water. A transport device and a transferrable lifting crane for positioning the frame assembly are moveable along the length of the bridge along guide tracks provided in the bridge.

A system for mixing and mixing processes and structures are disclosed. In addition a nozzle used for mixing is disclosed.

A system to treat effluent in a septic tank includes filter sections having kerfs. A strainer removes solid debris from the filter for removal without allowing the solid debris to pass. An aerator includes an eight to twelve inch diameter pipe 4 to 6 feet tall matching tank invert height. The aerator has bottom inlet holes, each with an elbow on the outside with a vertical standpipe taking effluent from the clear zone, sending it through the aerator. Air inlet piping is attached to a “T” shaped air diffuser producing bubbles traveling upward through plastic media. Aerator height is field adjusted to approximately 2 inches below static water level. Holes in the upper sidewalls just below the top let air bubbles out sideways. At its top, the aerator has a slotted, sliding, anti-turbulation collar adjusted to be one to two inches above the static water level.

A dual-action water aerator includes structure that generates fine, fizz-type bubbles and structure that generates larger, more roiling bubbles that cause circulation within a body of water in which the aerator is submerged. The disclosed embodiments include a ring-shaped hub with a central aperture, with a central tube extending axially from the aperture. A number of fine-bubble-producing members extend outwardly from the hub and may be attached to the hub using a twist-lock connection designed to facilitate rapid assembly and deployment of the aerator. An internal air chase extends circumferentially around the aperture. A portion of air supplied to the air chase flows into the fine-bubble-producing members and fizzes out through the members, and another portion of air that is supplied to the air chase flows into the central tube and bubbles up out of the tube in a roiling manner to cause circulation in the body of water.

The aerator system incorporates a land-based or water-based floating solar activated water aeration system with integrated linear diaphragm air compressor and controller to provide improved oxygen addition into water. The system uses low voltage and an advanced controller with max power point tracking (MPPT) technique, which converts the solar panel photovoltaic low voltage DC to low voltage AC and allows power generated from each solar panel to be fully utilized.

Provided is a washer liquid supply system in a simple structure and capable of improving the capacity of washing an object of a vehicle. A washer liquid supply system includes: a washer tank mounted on a vehicle to store washer liquid; a supply section mounted on the vehicle to supply the washer liquid in the washer tank to a window shield of the vehicle; and a connecting member being a bubbling section mounted on the vehicle to make the washer liquid contain bubbles, wherein the supply section supplies the washer liquid containing the bubbles to the window shield.

A liquid mixing system includes a support housing at least partially bounding a compartment. A mount is secured to the support housing. A drive motor assembly is configured to engage a drive shaft for moving the drive shaft within the compartment of the support housing. A four bar linkage system extends between the mount and the drive motor assembly, the four bar linkage system being movable between a first position wherein the drive motor assembly is disposed at a first elevation and a second position wherein the drive motor assembly is disposed at a second elevation that is different from the first elevation.

A water treatment system for aeration of water in a treatment tank includes at least one bridge extending above an upper surface of the water in the tank; a retrievable mounting frame assembly, including a frame, a plurality of aeration elements, a plurality of mounting brackets to secure the aeration elements to the frame, a control arm having secured to the frame at the first end, and a first air distribution conduit coupled to the aeration elements for supplying an air flow to the aeration elements; at least one guide rail system secured to the bridge assembly and extending to the floor of the tank, the guide rail system having at least one or multiple parallel guide rails, a second air distribution conduit coupled to the first air distribution conduit, and an actuatable push-rod positioned between the guide rails and connected to the control arm's second end. The hold-down rod, when actuated, moves the mounting frame assembly along the guide rails from a first position above the upper surface of the water and into a second position on the floor of the tank for aeration of the water. A transport device and a transferrable lifting crane for positioning the frame assembly are moveable along the length of the bridge along guide tracks provided in the bridge.

A system for mixing and mixing processes and structures are disclosed. In addition a nozzle used for mixing is disclosed.

A microbubble generator and a laundry treating device. The microbubble generator includes: an air dissolving tank, having an air dissolving cavity defined therein, and an inlet and an outlet configured to feed and discharge water, the inlet being located above the outlet, the inlet and the outlet being staggered in a horizontal direction; and a cavitator, provided outside the air dissolving tank and connected with the outlet, or provided at the outlet.
