Filtering irrigation water with media (sand/gravel) filters, also known as depth filtration for irrigation systems. The media filters perform the filtration of water through a thick layer of graded particles. These particles can be sand, gravel or other granular sorted materials. The filtration grade depends on the effective size of the bedding and the water velocity passing through the filter.
How the Sand / Media filters work:
Water enters through the filter inlet and percolates through the filter bed. When suspended matter comes in contact with media particles, it absorbs it. Clean water then goes via the strainer collectors, located on the bottom of the filter tank through the filter outlet. Cleaning is done by backwashing. Water is inserted in reverse direction - from the strainer collectors upwards, causing suspension of the filter bed, thus releasing the suspended materials from the bedding and it is flushed out through a backwash valve. Backwashing may be done automatically according To pressure differential and/or according To time intervals. When your water source is a river, open reservoir or wastewater, media filters might be the heart your drip irrigation system.
