A: It’s possible that your oxygen concentrations are too low, (usually less than 1 ppm), and the interior of the floc particle has become anaerobic, causing the nitrate oxygen to be utilized.
If only de-nitrification were this simple. In reality, de-nitrification is a complex issue that involves many aspects of your treatment and plant operations and all aspects must be considered when creating a prevention strategy or when troubleshooting a problem. It can be difficult to determine if you should increase oxygen levels, change the rates of return or the speed of the sweeper arm, and/or change the MLSS (mixed liquor suspended solid) concentrations. At AQUAFIX, we have the expertise to help our customers resolve even the toughtest de-nitrification problems. Let us put our knowledge to work for you.
