Hi,

Great comments below.

With your pH being around 8, its actually quite beneficial for you. pH correction is  not necessary. The highest rate for nitrification is achieved around pH 8.1. When nitrification begins to occur you get a reduction in pH as alkalinity is consumed.

As Mike Dooley said below, during denitrification you get an increase in alkalinity 3.57g of alkalinity per gram nitrate. This might be occurring post aeration, in settlement stage (after ammonia has been broken down to nitrate). A good identification is small air bubbles in the water during settlement.

As you have just reseeded your SBR, I presume you still have quite a young sludge age. Keep WAS to none or minimum and treatment should get better in time.

Did you have this issue prior to reseeding?
