Nitrification consumes approximately 7.1 mg of alkalinity for every <br /> milligram of ammonia-nitrogen(NH;N) oxidized and since the ammonia-nitrogen concentration <br /> can be considered high from the septic tank analyses obtained, alkalinity requirements will be high. <br /> If there is insufficient alkalinity, this may not buffer the pH during nitrification,which reduces the <br /> performance of bacteria in removing BOD and ammonia. <br /> 9 <br /> Chesney Consulting <br />
