Abstract: The backwash process consists of water passing through the filter in the opposite direction of the filtering flow to remove organic and inorganic particles of media filter. Inefficient sand filters designs and the occurrence of inadequate operating conditions contribute to restrict the process performance, causing deficiencies in the filter cleaning and compromise the operation of localized irrigation systems. The objective of this study is to provide a review about concepts associated with the backwash process in sand filters, relating literature information with laboratory experiments. A basic documentation was produced with technical and scientific information on this subject to create a reflection about the backwash process and contribute to the improvement of the equipment performance in the localized irrigation.
