Resumo: | This research aimed to verifying the intensity of chemical precipitates in five different drip hoses models on water containing a high amount of total iron. The irrigation system was assembled with one reservoir of 1000 L, a set of motor pump of 0.5 cv, a 120 mesh filter disk, a test banch measuring where it was installed the drip hoses. The system was evaluated estimating the average flow rate, variation flow coeffícient (VFC), uniformity of distribution/emission and relative flow rate. It was possible to observe, during the days of the tests, and also at the end of the research (around 400 h of irrigation), that the chemical sediments of iron, deterioreted the performance of the drip hoses, promoting a great reduction in their flowing. The degree and the intensity of obstruction varied according to the model, observing that the makes which demanded more strictly fíltration (R and C), with a similar design aspects, labyrinths: R, Q and C, showed to be more susceptible to clogging problems. In the studies conditions it could be concluded, that the utilization of water, with that total iron concentration (3 mg.L-1), showed to compromise the irrigation performance. |
