One of the key things is bacterial population and sludge age. If the bacteria are too young then you may have wasted out too many nitifiers. They are extremely sensitive, as you know. I would start with adding liquid nitrifiers (nitrosoma/nitrobacter blend usually kept cold in a suspension). 4 gallons per shift to each aeration basin to grow back the nitrifying colonies. You should be able to monitor the mixed liquor under the scope for the increase in colonies. Should take about a week but you should see an impact day 3. Thanks, Sean

1.The sludge we drain is 5 mins every 30 mins, and now we plan to lower the drain time, to increase the sludge age.
2.we pump the sludge from other system (which is good to NH3-N reduction) as usually, but this time the NH3-N reduction rate is poor to improve .
