    Abstract: In order to incorporate oxygen into waters there is immersed therein at least one container or vessel which contains liquid oxygen. The oxygen is released into the water. The container is formed at least in part of a water soluble material, so that there results automatic release of the oxygen. Hence, oxygen can be introduced into deeper situated layers of the water without otherwise impairing the waters. With this equipment and technique there is avoided the need for complicated installations and there are not issued any emissions.
