Venturi Injectors (Eductors)
Works 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 creates suction at the injection port. The chemicals that are injection are rapidly dispersed through this high velocity “rapid mix” section.
High chemical diffusion (up to 95%)
Excellent choice for gas/liquid injection (Ozone, CO2, Oxygen, Air)
Does not easily plug or lose efficiency over time compared to a porous injector
No moving parts
- Low cost

Dilution System Using a Venturi Eductor
The dilution system shown below is for diluting 12.5% sodium hypochlorite (NaOCl) to a more stable 3-5% concentration solution for potable water disinfection. The eductor combines the two flows of potable water and concentrated NaOCl and thoroughly mixes the flows before being stored in a storage tank.Turning the dilution system on is simple. The water valve is turned on. This motive water will draw the concentrated NaOCl from a tank or carboy without the use of pumps.
