Venturi Injectors work by forcing water through a conical body which initiates a pressure differential between the inlet and outlet ports. This creates a vacuum inside the injector body, which initiates ozone suction through the suction port.
Water flows from left to right; ozone is introduced into the middle.
Air being sucked into a venturi/injector - notice the thousands of small bubbles present after the suction port.
Injectors produce thousands of bubbles greatly increasing the surface area of oxygen, or ozone, in contact with the water. (Two small bubbles have greater surface are than one large bubble of the same volume.) This results in a very high mass transfer rate.
Bubble Diffusers work by emitting ozone through hundreds of bubbles beneath the water's surface.
This is an example of a bubble diffuser bubbling ozone into an aqueous solution.
