Abstract

Pure oxygen aeration is a method of recharging oxygen-depleted waters. Under some circumstances, however, oxygen can escape at the surface of the water. This release may result in a dangerous, oxygen-enriched atmosphere. Procedures for calculating oxygen concentrations and the results for certain cases are given.

If there is a wind of 1 m/s or more, the oxygen enrichment does not exceed 22.8 vol% O² at distances of 2 m or more from the source. Under conditions of dead calm, however, oxygen enrichment increases steadily with time. A safety philosophy for avoiding any dangerous oxygen emission is explained as applied at the Teltow Canal in West Berlin.
