IVG-IR Usage Impact on Lettuce Growth

The main objective of this study by the Vineland Research & Innovation Centre was to measure the impact of the IVG water treatment on the germination rate, relative chlorophyll content, fresh weight, and marketable yield, on the root length, and root biomass of the plants.

The Vineland Research & Innovation Centre in Ontario conducted a study on lettuce during August and September 2022. The impact of the IVG water treatment was noticeable and significant from the beginning and reported during the different stages of the plant growth: From seedling to the plant and root development. 

Installation at Vineland Research & Innovation Centre

An IVG-IR 1300 (1.3m3/h flow capacity) was installed inline at the test site. The system runs solely off water pressure (minimum 45 psi) and is installed based on the size of an existing pipe system, in this case 3/4 inch (capable up to 2 inch). 

The gases are expelled out of the outlet as the vortex separates the un-dissolved gases, they rise to the top of the IVG and follow a linear path away from the vortex water. This allows for the gases to dissipate into the air while the water flows out of its end point. 

No air re-leave valve was needed after the IVG-IR.
