Oxygen Enrichment. Oxygen enrichment is relatively rare, but constitutes an extreme fire hazard. It usually results from improper handling of Liquid Oxygen or Oxygen mixtures with other gases above atmospheric concentration of 20.9% by volume. 23.5% Oxygen by volume is considered enriched.
Method to increase the oxygen level in oxygen deficient or depleted water bodies or water bodies that will face oxygen deficiency or depletion in the future

The present disclosure relates to a method and a system to increase the dissolved oxygen content in a water body having a dissolved oxygen content of between 0 mg / l and 4 mg / l, or to anticipate a future drop of a dissolved oxygen content of a water body to between 0 mg / l and 4 mg / l, wherein the water body is non-stratified, or is stratified and comprises at least an epilimnion, wherein the method comprises a step a, wherein a stream of diluted aqueous nitrate containing liquid droplets of which at least part are diluted oxygenated aqueous nitrate containing liquid droplets are formed, and a subsequent step b, wherein the diluted aqueous nitrate containing liquid droplets of which at least part are oxygenated diluted aqueous nitrate containing liquid droplets are further spread, in case of a non-stratified water body, in a part of the water body or in the whole water body, and in case of a stratified water body, in a part of the epilimnion of the water body or in the whole epilimnion of the water body.
