Irrigation systems water filtration, Media and disc filters [2 out of 5]
Filter media
Filtering irrigation water with media (sand/gravel) filters also known as depth filtration. 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.
Disc Filters
Disc Filters integrate the benefits of the old filtering methods screen and media, as well as having their own unique advantages. Manual disc Filters are useful for filtration of both sand granules and a variety of organic materials. Disc filters are the best choice for almost any micro irrigation systems.
Small Nylon discs are grooved on both sides of each disc to a specific micron size. A series of these discs are then stacked and compressed on a specially designed spine. When stacked, the groove on top runs opposite to the groove below, creating a filtration element with a statistically significant series of intersecting grooves which trap the solids. The stack is enclosed in corrosion and pressure resistant housing. During filtration, the discs are tightly compressed together by a combination of either spring power or tightening nut and the differential pressure, thus providing high filtration efficiency. Filtration occurs while water is percolating from the outer diameter to the inner diameter of the element. Depending on the micron grading, in irrigation water filtration it is common to use from 18 (in 400 micron discs) to 32 (in 20 micron discs) disc quantity per each 1 cm of the spine length stopping points in each track, thus creating the unique in-depth filtration. During the filtration process, the filtration discs are tightly compressed together by the spring’s power (or tightening nut) and the differential pressure, thus providing high filtration efficiency. Filtration occurs while water is percolating from the peripheral end to the core of the element.
The Disc Filter is cleaned by unscrewing the disc’s tightening nut, and wash the released discs under strong flow of water. The discs roll around a central spine rapidly, thus part of the dirt is separated due to the centrifugal force.
For automatically cleaning the discs, there is a releasing mechanism of the clamp between the discs, thus separated from each other the trapped particles are released and back-washed, know methods called Spin klin and Spin clean.
