Anaerobic lagoon profile studies were undertaken in perspex columns which were either unaerated (A), or aerated to a depth of 8 (B), 20 (C) or 40 cm (D). The dissolved oxygen level in the aerated columns was maintained at approximately 70% of saturation and all columns were loaded at the daily rate of 50-55 g BOD5/msuperscript 3. Temperature was maintained at about 20 degrees C and the retention time averaged 128 days.
