Impact of Upflow Gravel Filtration on the Clogging Potential in Microirrigation

Abstract

This paper evaluates the effect of six water treatment combinations for the treatment of turbid surface water on four types of emitters by looking at clogging potential and distribution uniformity. The pilot plants use different combinations of upflow gravel filtration, disc filters, and slow sand filtration, fed with natural water from the Cauca River (Cali, Colombia). The outflow of these systems was used to feed four different types of emitters. The paper analyzes the removal of physicochemical parameters that affect emitter clogging and the distribution uniformity of the lower quarter (
