* The efficiency tests were conducted in practice on drain water from a rockwool substrate. Water with higher organic contamination, such as crops on water and crops using potting soil, causes even faster contamination of the nanobubble generator (Brand ‘M’). It is 100% guaranteed at O2solutions that the dissolution rate remains the same all year round with any water type.
** Due to fouling of the system (Brand ‘M’), oxygen flow slowly decreases and the operator needs to continuously check and adjust the system to avoid failure.
