Whether it is a garden, lawn, golf course or even your backyard you are irrigating, you will need to filter your water regularly. Irrigation water often contains several organic and inorganic substances. This debris gets trapped in irrigation systems, leading to blockages that eventually cause uneven irrigation. With sprinkler systems, for instance, this could result in blocked sprinkler heads leading to patches of dryness dotting the vast green areas of your lawn. The type of water filter system you need to counter this depends on a number of factors. Your irrigation system, for a start, will determine the best filter system for you. The type of water, and even the location of your irrigation system, may also determine the most suitable water filter system for you. The following are some of the common water filter systems and where they are most applicable.
Cartridge filters employ the use of a rough filtration paper assembled into a cartridge. The cartridge paper's rough surface filters the water from most inorganic debris such as sand, rocks, soil, leaves, and more. In cases where the cartridge is made of very rough, but fine filters, they can also filter organic substances such as bacteria films and algae. Cartridge filters are usually replaced, but in some cases, the cartridge can simply be washed and re-used.
Screen filters are some of the most popular filters used for irrigation. Their preference is mainly due to their inexpensive nature and ease of maintenance. The screens can be removed and washed by hand when debris builds up or flush-washed by a powerful water jet. They are very useful when your irrigation system is exposed to particulates such as sand, silt, rocks and other hard substances.
These also operate well to remove particulate debris. Centrifugal filters spin water, settling the larger and harder debris at the bottom of the centrifuge, and then letting the filtered water proceed for irrigation. The sediment is deposited separately, and, therefore, these filters don't need frequent replacement, making them an ideal choice for a water filter system when irrigating crops.
In these, the irrigation water is forced into an area containing a filtration screen, as well as filtration media. The filtration screen handles filtration of sediments such as sand and soil, while the filtration media can achieve filtration of both organic and inorganic substances. From this combination, disc filters tend to be more thorough with their filtration and discharge water of better filtration quality. Disc filters are cleaned by removing the discs and flushing before reassembling the disc arrangement.
