Lateral flushing with fresh water reduced emitter clogging in drip irrigation with treated effluent

Emitter clogging is a persistent problem for drip irrigation using treated effluent. To find an effective flushing regime, research was conducted using two water types (treated effluent and fresh groundwater) with two flushing frequencies (every irrigation event and every five irrigation events) and a control (no flushing). Thin-wall laterals with inline-labyrinth emitters were examined. The irrigation duration was 1 h daily for 91 days. Emitter...
