Resumo: Drip irrigation systems stand out for the use of wastewater, by minimizing water losses and risks to the environment and public health, however, the clogging of emitters is a potential problem in this technology. The objective of this study was to evaluate the flow coefficient of variation (FCV) and the coefficient of statistical uniformity (CSU) of drip irrigation units operating with water-diluted landfill leachate. The experiment was conducted in a completely randomized split-plot design, with emitter types in the plots (G1 - non-pressure compensating, and G2, G3 and G4 - pressure compensating) and evaluation times in the subplots (0, 20, 40, 60 80, 100, 120, 140 and 160 hours), with four replications. The FCV, CSU and physicochemical and biological characteristic values of the dilute landfill leachate were determined every 20 hours to complete 160 hours of operation of the drip units. The biofouling caused major value changes in the FCV and the CSU of the drip unit with the G1 emitter (non-pressure compensating) compared to the units with the G2, G3 and G4 emitters (pressure compensating). The G3 emitter was the most adequate for applying the dilute landfill leachate.

Objetivou-se com este trabalho avaliar o coeficiente de variação de vazão (FCV) e o coeficiente de uniformidade estatístico (Us) de unidades gotejadoras abastecidas com percolado de aterro sanitário diluído em água de abastecimento. O experimento foi conduzido sob delineamento inteiramente casualizado no esquema de parcelas subdivididas, tendo nas parcelas os tipos de gotejadores (G1 não autocompensante; e G2, G3 e G4 autocompensantes) e nas subparcelas os tempos de avaliação (0, 20, 40, 60, 80, 100, 120, 140 e 160 horas), com quatro repetições. Os valores de FCV, CSU e das características físico-químicas e biológicas do percolado de aterro sanitário diluído foram determinadas a cada 20 horas, até completar 160 horas de operação das unidades gotejadoras. A bioincrustação proporcionou maiores alterações nos valores de FCV e CSU da unidade gotejadora com gotejador G1 (não autocompensante) em relação às unidades dotadas dos gotejadores G2, G3 e G4 (autocompensantes). O gotejador G3 foi o mais adequado na aplicação do percolado de aterro sanitário diluído.Universidade Federal Rural do Semi-Árido2016-03-12info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/371710.1590/1983-21252016v29n119rcREVISTA CAATINGA; Vol. 29 No. 1 (2016); 163-172Revista Caatinga; v. 29 n. 1 (2016); 163-1721983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/3717/pdf_348Copyright (c) 2023 Revista Caatingainfo:eu-repo/semantics/openAccessMesquita, Francisco de OliveiraAlves, Sandra Maria CamposBatista, Rafael OliveiraDantas, Tarcísio BatistaSouza, Luiz Di2023-07-19T13:38:35Zoai:ojs.periodicos.ufersa.edu.br:article/3717Revistahttps://periodicos.ufersa.edu.br/index.php/caatinga/indexPUBhttps://periodicos.ufersa.edu.br/index.php/caatinga/oaipatricio@ufersa.edu.br|| caatinga@ufersa.edu.br1983-21250100-316Xopendoar:2024-04-29T09:46:08.441553Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true
