Resumo: Clogging tendency has been analyzed in sandy soil soakaways at pilot scalereceiving either septic tank effluent (SUM1) or UASB effluent (SUM2) andalso at laboratory scale (SUMB1 and SUMB2), in relation to Chemical OxygenDemand (COD) and accumulated Suspended Solids (SS) concentrations.Clogging was also estimated, by modeling the predicted time for infiltrationhydraulic failure. The laboratory results obtained with SUMB1 and SUMB2confirmed the results obtained for SUM1 and SUM2, showing thatsoakaways built in sandy soils which receive effluent from septic tankstreating predominantly domestic wastewater tended to clog 58% faster thanthose receiving UASB effluent. The good correlation observed between thedecrease in average infiltration rate and the time of operation suggests thatthe UASB reactor is a promising technological alternative to septic tanksas a pre‑treatment prior to effluent soil disposal for on‑site decentralizedwastewater treatment systems.

Estimou‑se ainda, por meio de um modelo, a predição do tempo para a falha hidráulica. A colmatação do SUMB1 à frente do SUMB2 confirmou os resultados de campo obtidos para os SUM1 e SUM2, demonstrando que sumidouros construídos e operados recebendo esgoto doméstico tratado em tanque séptico em solos arenosos tenderão a colmatar 58% mais rápido do que aqueles com tratamento prévio em reatores UASB. A boa correlação entre o decréscimo da taxa média de infiltração nos sumidouros em função de período de operação sugere o reator UASB como promissora alternativa aos tanques sépticos para disposição de efluentes no solo em sistemas descentralizados unifamiliares de tratamento de esgotos.Zeppelini Publishers2017-07-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://www.rbciamb.com.br/Publicacoes_RBCIAMB/article/view/12210.5327/Z2176-947820170413Revista Brasileira de Ciências Ambientais (Online); n. 43 (2017): RBCIAMB - ISSN 2176-9478 - Março; 131-139Brazilian Journal of Environmental Sciences (Online); No. 43 (2017): RBCIAMB - ISSN 2176-9478 - March; 131-1392176-94781808-4524reponame:Revista Brasileira de Ciências Ambientais (Online)instname:Associação Brasileira de Engenharia Sanitária e Ambiental (ABES)instacron:ABESenghttps://www.rbciamb.com.br/Publicacoes_RBCIAMB/article/view/122/90Copyright (c) 2017 Revista Brasileira de Ciências Ambientais (Online)info:eu-repo/semantics/openAccessOliveira Junior, José Lima deSousa, José Tavares deSantos, Andressa MunizSilva, Saionara Alexandre da2022-02-22T22:08:01Zoai:ojs.www.rbciamb.com.br:article/122Revistahttp://www.rbciamb.com.br/index.php/Publicacoes_RBCIAMBhttps://www.rbciamb.com.br/Publicacoes_RBCIAMB/oairbciamb@abes-dn.org.br||2176-94781804-4524opendoar:2022-02-22T22:08:01Revista Brasileira de Ciências Ambientais (Online) - Associação Brasileira de Engenharia Sanitária e Ambiental (ABES)false
