description Ammoniacal nitrogen in Sanitary Landfill Leachate may reach concentrations up to 2000 mg/L, which, if discharged into the environment under such concentrations, may cause severe environmental and public health impacts. The stripping process is a technical highlight among the alternatives for leachate ammoniacal nitrogen removal employed worldwide. The comparison of the analyses performed at inflow and outflow, at the São Leopoldo/Brazil Leachate Treatment Plant wastewater (lagoons), showed an ammoniacal nitrogen removal rate that ranged between 38% and 65% in 90 days of HRT. On the other hand, the Baffled Reactor yielded a 73% removal rate in 12 days. Statistically, the “temperature” variable affected Ammoniacal nitrogen removal, such that the higher removal rates were associated to environmental temperatures above 20ºC, thus rendering this technology as useful in tropical countries. The Baffled Reactor demonstrated to be applicable for use in sanitary landfills that produce 0.33 m³ of leachate per day. This value corresponds to service provided to a small scale municipality with a population of up to 10.000 inhabitants. Treatment operational cost using the reactor was estimated to be US$ 30.25/m3 of treated leachate, which is an interesting result if compared with other ammoniacal nitrogen removalunits, as well as with ex situ treatment processes.Key Words: Landfill, Leachate treatment, Ammoniacal nitrogen removal.

O processo de stripping é uma das técnicas que se destaca entre as alternativas para remoção de nitrogênio amoniacal de lixiviados empregados em todo o mundo. A comparação das análises realizadas na Estação de Tratamento de Lixiviado de São Leopoldo/Brasil, na entrada e saída, mostrou que o tratamento biológico utilizado atualmente no local (lagoas) para o tempo de retenção hidráulica de 90 dias, produziu uma taxa de remoção de nitrogênio amoniacal, que variou entre 38% e 65%. Por outro lado, o reator de chicanas (reator compartimentado) rendeu uma taxa de remoção de 73% em 12 dias. Estatisticamente, a variável "temperatura" afetou a remoção de nitrogênio amoniacal, de tal forma que as maiores taxas de remoção foram associadas a temperaturas ambientais acima de 20 ºC, tornando, assim, essa tecnologia tão útil em países tropicais. O reator de chicanas demonstrou ser aplicável para uso em aterros sanitários que produzem 0,33 m³ de lixiviado por dia. Este valor corresponde ao serviço prestado em um município de pequeno porte, ou seja, com uma população de até 10.000 habitantes. O custo operacional do tratamento usando o reator de chicanas estudado foi estimado em US$ 30,25/m3 de lixiviado tratado, o qual é um resultado interessante, se comparado com outras unidades de remoção de nitrogênio amoniacal, bem como com os processos de tratamento ex situ.Palavras chaves: Aterro Sanitário, Lixiviado, stripping. AIDIS / Instituto de Ingeniería, Universidad Nacional Autónoma de México2014-04-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtículos evaluados por paresArtículos evaluados por paresArtículos evaluados por paresapplication/pdfhttps://revistas.unam.mx/index.php/aidis/article/view/46610Revista AIDIS de ingeniería y ciencias ambientales: Investigación, desarrollo y práctica; Vol. 7, No. 1, 6 de Abril de 2014; 19 - 32Revista AIDIS de ingeniería y ciencias ambientales: Investigación, desarrollo y práctica; Vol. 7, No. 1, 6 de Abril de 2014; 19 - 32Revista AIDIS de ingeniería y ciencias ambientales: Investigación, desarrollo y práctica; Vol. 7, No. 1, 6 de Abril de 2014; 19 - 320718-378Xreponame:Revista AIDIS de Ingeniería y Ciencias Ambientales: investigación, desarrollo y prácticainstname:UNIVERSIDAD NACIONAL AUTÓNOMA DE MÉXICOinstacron:UNAMspahttps://revistas.unam.mx/index.php/aidis/article/view/46610/41849info:eu-repo/semantics/openAccessoai:ojs.pkp.sfu.ca:article/466102024-08-16T18:32:50Z
