- Abstract
The use of statistical quality control tools in irrigation has been disseminated because it provides a fast and efficient detection of possible problems in drippers, especially when wastewater is used in irrigation. Thus, this research aimed at using statistical quality control charts to monitor the degree of clogging of drip irrigation units irrigated with diluted fecula wastewater. The research was performed in an experimental area belonging to the Laboratory of Irrigation and Drainage Engineering (LEID), of the Universidade Federal de Campina Grande - UFCG, Campina Grande Campus, Paraíba, Brazil. Four different dripper units were evaluated every 20 hours, for 480 hours, totaling 25 trials, with service pressure of 100 kPa. When comparing the Shewhart statistical control charts with the exponentially weighted moving average (EPM) charts, it was observed that the EPM charts were more sensitive to minor variations. Furthermore, it was observed that the diluted fecula residue water increased clogging problems in the dripline models M1 and M3 during 480 hours of irrigation and that the use of raw fecaria residuary water is not recommended for localized irrigation, because it presented high levels of calcium and magnesium hardness, sodium and chlorides.
