Abstract
A method and nitrification system for nitrifying a centrate stream produced from dewatering sludge within a wastewater treatment facility in which the centrate stream into a nitrification reactor containing accumulated centrate with a bacterial population of AOB and NOB nitrifying bacteria to the ammonia content within the centrate stream into nitrates and an oxygen containing gas is introduced into the accumulated centrate to support bacterial activity of the AOB and NOB nitrifying bacteria. Additionally, a conditioning method is obtained in which the bacterial population is grown within the nitrification reactor in conditioning stages that involve the introduction of incoming centrate into the reactor with a successively decreasing degree of dilution.
