    Abstract: A flow control arrangement for use with a pump in an aquarium includes a main body having an inlet flow conduit and an outlet flow conduit. The main body has a cylindrical wall having first and second opposite open ends and defining an open interior; and a through hole extending through the wall to the open interior. A flow control dial closes the first open end; and an aeration flow dial closes the second open end and is rotatably adjustable relative to the main body. The aeration flow dial has a tubular aeration wall extending into the open interior. The aeration wall has an aperture, wherein the aeration flow dial can be rotatably adjustable to control axial alignment of the aperture with the through hole in the wall of the main body to selectively adjust a size of a resulting orifice from the open interior of the main body to outside of the main body.

    Abstract: Systems and methods for injecting hydrogen into a natural gas pipeline to lower the carbon intensity of the resulting fuel blend while achieving the required energy output thereof for the end user. In one embodiment a blend ratio for the blended fuel comprising hydrogen and natural gas is determined based at least in part on a minimum energy output for fuel combusted at an end-use location connected to the natural gas pipeline so that the blended fuel (i) has a lower carbon intensity than a natural gas stream flowing in the natural gas pipeline, and (ii) provides at least the minimum energy output when combusted at the end-use location. Further, one or more embodiments include adjusting a control valve of a hydrogen injection assembly connected to the natural gas pipeline upstream of the end-use location based at least in part on the blend ratio to thereby mix hydrogen into the natural gas pipeline and produce the blended fuel.

    Abstract: The contacting device for countercurrent contacting of fluid streams and having a first pair of intersecting grids of spaced-apart and parallel deflector blades and a second pair of intersecting grids of spaced-apart and parallel deflector blades. The deflector blades in each one of the grids are interleaved with the deflector blades in the paired intersecting grid and may have uncut side portions that join them together along a transverse strip where the deflector blades cross each other or adjacent opposed ends of the deflector blades and cut side portions that extend from the uncut side portions to the ends of the deflector blades. At least some of the deflector blades have directional tabs and associated openings to allow portions of the fluid streams to pass through the deflector blades to facilitate mixing of the fluid streams.

    Abstract: A multi-fluid blending system employing low-energy static mixing provides efficient mechanical blending process for mass-producing thermodynamically stable hydro-fuels, eliminating the need of high-energy mixing equipment, and maintaining a compact, cost-effective design. Suitable for small to large-scale production, the system produces microemulsions following Hydrophilic-Lipophilic Difference (HLD) surfactant formulations. Modular design allows for scalable applications, from equipment installations to trailer-mounted units and onboard ships. The system ensures the production of hydro-fuel microemulsions using precise metering, dosing systems and low-energy static mixing. Hydro-fuels produced reduce engine combustion emissions and harmful pollutants, hydrocarbons, particulate matter, black carbon and smoke opacity, benefiting the environment and human health.

    Abstract: Water treatment systems and methods are described herein for optimizing the formation and delivery of ozone-filled nanobubbles for disinfecting a volume of water. In an example system for treating water in a pool, such as a swimming pool, a control valve located downstream relative to a pool pump draws a select volume of water into through a circuit of elements including a pump assembly, a Venturi assembly for injecting a supply of ozone-rich gas into the water, a pressure vessel, and a nozzle assembly for generating a variable concentration of ozone-filled nanobubbles in the water. The ozone-filled nanobubbles in the pool water are stable, safe and odorless, and far more effective than chlorine or ozone alone. With the ozone-filled nanobubbles in the water column, the measurable concentration of dissolved ozone in the water is remarkably steady under a variety of operating conditions.
