WebThe lab-scale CAS and predenitrification BNR reactors had very comparable operational conditions. For example, both systems were seeded with the same activated sludge collected from a local WWTP (Amherst, MA, US) and were run in sequencing batch mode with 4 cycles. Each cycle (6 h) constituted 10 min influent feeding, 290 min treatment ... WebJul 15, 2024 · The optimization of biological nitrogen removal (BNR) in sequencing batch reactors has become the aim of researchers worldwide in order to increase efficiency and reduce energy and operating costs. This research has focused on the nitrification phase as the limiting reaction rate of BNR. This paper analyzes different strategies and discusses ...
