Maintaining the alkalinity of your wastewater is particularly essential to the nitrification bacteria, which consume large ... WebIt takes residence or contact time during wastewater treatment for the pH to adjust appropriately. A very narrow pH range (i.e., 7.0 to 8.0) requires less contact or residence time as compared to a wider pH range (i.e., 7.0 to 10.0), so the procedure is affected by the required pH adjustment range.
