ABSTRACT

Filtration of water to remove particulate matter and biological contaminants is critical to the efficient operation of many pressurized irrigation systems. Filtration for sprinkler irrigation systems, where there are largesize water contaminants that can clog the sprinkler nozzles, is usually done with screen or disk filters. Microirrigation systems, with small flow passageways in the drip emitters and microsprinklers, may use screen, disk, or sand media filters to remove small particulates and organic contaminants to prevent clogging. The choice of which filter to use is often based on the water quality.
