摘要：
One of the most important advantages of drip irrigation is the possibility of achieving a high uniformity of water distribution. However, this uniformity can be reduced when using water with high iron content, which can cause drippers to clog. This study aimed to verify the efficiency of the chlorination, aeration, decantation and filtration processes carried out to remove the iron from irrigation water and to investigate the effect of iron on water distribution uniformity. Four similar irrigation systems with five models of drippers were installed. The results showed that (i) there was a significant difference in the drippers' behavior in relation to susceptibility to clogging when using water with a high iron content; (ii) the use of disk filters alone was not able to promote significant reductions in the iron quantity as a way to prevent the clogging of drippers; and (iii) the use of aerators followed by sedimentation tanks made it possible to achieve a considerable improvement in the water application uniformity for drippers that were more sensitive to clogging caused by the use of water with high iron content.
