Abstract |
The oxidation channel treatment plant constructed at Glenwood, Minnesota, was set up as a demonstration plant to determine whether or not this process would be more efficient in the removal of nitrogen from sewage than has been the experience with other types of biological treatment. It was felt that with this type of process it would be possible to satisfy the biochemical oxygen demand of the sewage with a minimum amount of oxygen that would maximize (1) the storage of nitrogen in the microbial protoplasm and (2) also release of gaseous nitrogen through denitrification.
