Resumo: The aim of this study was to apply optical microscopy and scanning electron microscopy (SEM) techniques to identify and assess dripper clogging of an irrigation system. Three dripper models (Taldrip, Streamline, and Tiran) underwent 1200 hours of irrigation with three types of effluents: treated domestic wastewater, water with a high calcium content, and urban water supply. Samples of the material adhered to the inside of drippers were analyzed by means of the smear method aiming at their biological identification. Other samples were taken to obtain SEM images. The presence of algae, bacteria, and biological components of biofilm was observed in drippers operating with wastewater and water with calcium, this latter in a low number. The formation of biofilm and chemical precipitates of calcium were observed in SEM images, leading to emitter clogging. Optical microscopy and SEM analyses allowed identifying the degree of fouling by biofilm and chemical precipitates in dripper clogging.

Três modelos de gotejadores (Taldrip, Streamline e Tiran) foram submetidos a 1200 horas de irrigação com três tipos de efluentes: água residuária de esgoto doméstico tratado água com elevado teor de cálcio e água de abastecimento urbano. Amostras do material aderida no interior dos gotejadores foram analisadas pelo método de esfregaço para fazer a identificação biológica, outras amostras foram retiradas para realizar as imagens com MEV. Foi possível verificar a presença de algas, bactérias e componentes biológicos do biofilme, tanto nos gotejadores operando com água residuária, quanto naqueles que operavam com água com cálcio, esta última em menor quantidade. Nas imagens com MEV foi possível verificar a formação de biofilme que causou a obstrução dos emissores e também os precipitados químicos de cálcio. A análise por MEV e microscopia óptica permitiu identificar o grau de incrustação por biofilme e precipitados químicos na obstrução de gotejadores.Universidade Federal Rural do Semi-Árido2018-10-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/721410.1590/1983-21252018v31n423rcREVISTA CAATINGA; Vol. 31 No. 4 (2018); 997-1007Revista Caatinga; v. 31 n. 4 (2018); 997-10071983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/7214/9870Copyright (c) 2018 Revista Caatingainfo:eu-repo/semantics/openAccessRibeiro, Maycon DiegoAzevedo, Carlos Alberto Vieira deSantos, Delfran Batista dosSzekut, Flavio DanielKlein, Márcio RobertoReis, Claudia Facini2023-07-20T13:55:45Zoai:ojs.periodicos.ufersa.edu.br:article/7214Revistahttps://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:2024-04-29T09:46:34.116219Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true
