In this article, a review of nine new and innovative methods against emitter clogging is presented. Some of them used only freshwater sources (canal water and groundwater) and some of them compared the results of the preventive or treatment method for freshwater and TWW/RW. Though the flushing and filtration methods are well-known conventional methods, few research works delved on effects of varying the flushing pressure as well as frequency and hence they were included for review. Table 1 lists different methods reviewed by this study.

Various innovative methods of prevention and/or treatment of emitter clogging

Physical methods Flushing of laterals and use of filters 
Magnetizing the irrigation water 
Generating molecular oscillations using MERUS ring 
Pulsating or dynamic pressure application 
Ultrasound treatment of water 
Chemical methods Fertigation 
Application of N-halamine nano particles (NPs) 
Electrochemical method 
Biological methods Treatment with various antagonist bacterial strains (Bacillus spp, Burkholdria spp, Lactococcus garvieae and Bacillus amyloliquefaciens)
