Four reactors were operated in batch mode, two with zeolite (1 mm size) used as microbial support and two without support, to assess the effect of the zeolite addition in the SNaD. Aeration, anoxic, and anaerobic cycles were established, where 96% removal of NH4+-N (oxidized to nitrite or nitrate) was achieved in nitrification, along with 93% removal of NO3−-N in denitrification for the SNaD with zeolite. It was observed that the use of zeolite assists in buffering reactor load changes. Inhibition caused by nitrite accumulation in the denitrification stage was minimized by increasing the nitrogen concentration in the SWW. The results obtained in this study are the basis for the development of ammonium removal by simultaneous nitrification–autotrophic denitrification using a single reactor.This research was funded by ANID—Government of Chile, Regular Fondecyt Project 1201258.Peer reviewedMultidisciplinary Digital Publishing InstituteAgencia Nacional de Investigación y Desarrollo (Chile)Consejo Superior de Investigaciones Científicas [https://ror.org/02gfc7t72]202320232023info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501Publisher's versioninfo:eu-repo/semantics/publishedVersionhttp://hdl.handle.net/10261/287302https://api.elsevier.com/content/abstract/scopus_id/85146055270reponame:DIGITAL.CSIC.
