Particulate clogging problems (sands, silts, trash, etc.)
Depending on the size of the particulate matter, the best way to preventing emitter clogging will differ. Filters should be used with all waters that contain suspended particulate matter.
Some suspended particulate matter is small enough to pass through the filters commonly used for agricultural applications. However, these small particles will settle out, particularly in locations of slow flow velocity (e.g., ends of lateral lines). If the small particles build up in the microirrigation system, they can contribute to emitter clogging, so they should be periodically flushed from the system.
