Page "learned" Paragraph 1193

O'Connor and Eckenfelder discussed the use of aerated lagoons for treating organic wastes.

They indicated that a 4-day retention, aerated lagoon would give 60 to 76 per cent BOD reduction.

Later, Eckenfelder increased the efficiency of treatment to between 75 and 85 per cent in the summer months.

It appeared from the limited information available that the aerated lagoon might offer a satisfactory means of increasing the capacity of existing oxidation ponds as well as providing the same degree of treatment in a smaller volume.
