Device for the accumulation of oxygen in surface and deep water for standing or flowing oxygen-poor water

摘要

The assembly to enrich flowing or standing water with oxygen, in surface or subterranean water with a low oxygen content, the water is passed through a container with at least one inflow and outflow and divided into a prim. and sec. flow stream. The container has a sieve structure at or above the water level and the prim. flow is directed by a feed into the container from above, on to the sieve structure. An air flow is directed through the sieve structure from below from a ventilator, where part of the prim. flow floats on the sieve. The air flow feed to the prim. flow stream is interrupted in a following dwell zone, for the prim. stream to pass onwards over a further sieve structure and dwell zone and then drop out through the prim. flow stream outlet. The sec. flow stream is generated by a pump and a feed below the water level near the prim. flow outlet, for the prim. and sec. streams to be mixed together. ADVANTAGE - The assembly can process large vols. of low-oxygen water, whether surface water or subterranean, in a simple operation requiring little energy. The air with oxygen is strongly mixed by contact with the water to transfer oxygen ot it
