The AnoxKaldnes Hybas™, an innovative application of the proven AnoxKaldnes technology, can increase the capacity of a Sequencing Batch Reactor (SBR) wastewater treatment process in the same footprint as a conventional SBR without the need for additional tankage. The AnoxKaldnes Hybas™ for SBR uses engineered moving bed media to grow and foster nitrifying bacteria, even at low SRTs and low reactor temperatures. The process allows for greater nitrification capacity for ammonia (NH₃-N) removal. With recirculation, the same increase in nitrification capacity allows for both nitrification and denitrification to meet total nitrogen (TN) effluent limits. The AnoxKaldnes Hybas™ for SBR allows for a 30% increase in treatment capacity for systems needing to meet more strict NH₃-N or TN permit limits.
With over 50 AnoxKaldnes installations in the U.S., Kruger has built the most proven and successful track record in the MBBR and IFAS market. Now, Kruger can apply the same proven technology and process expertise to the retrofit of SBR’s for ammonia and TN removal with little civil construction.
