In these cases, supplying 1.25 to 1.80 pounds of oxygen per pound of BOD removed or higher is appropriate. 2. AMMONIA LOADING The …
WebAn oxidation ditch should come offline for maintenance only in the summer to avoid peak flows. This should only occur when there is a good SVI. A 20-day SRT should be maintained when an oxidation ditch is offline to maintain effluent ammonia requirements. The RAS rate will need to increase to at least 75% due to the higher MLSS.
