Nowadays, more and more farmland and plantations are beginning to use water-saving irrigation systems. This brings the efficiency of irrigation to a new level. Echter, during the actual use of irrigation systems, some problems may still occur.
Bijvoorbeeld, the water output may become smaller and smaller, en pijpen, druppels, and sprinklers may get clogged. The causes of these problems are most likely related to the filter. If the irrigation system is not equipped with a filter, or if the installed filter is unsuitable or substandard, or if the filter is not properly maintained, clogging problems can easily occur.
Daarom, the filter plays a very important role in the entire irrigation system. This post will give you a detailed introduction from four aspects: the importance of irrigation filters, the types of irrigation filters, the selection of irrigation filters, and the maintenance of irrigation filters.
Why Are Irrigation Filters So Important?
Let’s take a drip irrigation system as an example. In a drip irrigation system, the terminal water supply devices are usually drippers. Sometimes you may notice that the drippers work fine at first, but gradually, the water flow becomes slower and slower, and eventually, no water comes out at all. The reason for this problem is very likely that the drippers are clogged!
Some irrigation systems use water sources that are not suitable for direct irrigation. Bijvoorbeeld, well water, river water with a high sand content, enz. These water sources contain quite a lot of small sand particles and other impurities. If this water is introduced directly into the irrigation system without any treatment, even if it doesn’t clog the pipes, it will definitely clog the drippers.
Because the outlet holes of the drippers are very small, even very tiny particles and impurities can clog the drippers over time. Eventually, this will affect the operation of the entire irrigation system.
To prevent this problem, a filter must be installed at the water source to filter out the impurities in the water. Then, the clean water is delivered into the irrigation pipes. In this way, clogging will no longer occur.
The role of the irrigation filter is extremely important. If we compare the irrigation system to the human body, then the filter is like the kidneys — its function is to filter out all the “toxic” onzuiverheden!
Types of Irrigation Filters
Over het algemeen, the filter systems used in irrigation projects are divided into two levels: primary filtration and secondary filtration.
Primary filtration is the initial stage of filtration. If the irrigation system does not have strict requirements for water quality, then only primary filtration is sufficient. But for drip irrigation or sprinkler irrigation—these two methods require higher water quality standards, and it is necessary to avoid clogging of drippers or sprinklers—so secondary filtration with finer precision must be used, or even a combination of both primary and secondary filtration!
Primary filtration generally uses sand filters and hydrocyclone sand separators. Secondary filtration usually uses disc filters and screen filters. Below is an introduction to these four products:
Irrigation Sand Filter
This type of filter has a large tank, using sand and gravel as the filtering medium. It is mainly used to filter larger impurities. If there are many floating objects in the river or pond (leaves, algae, enz.), the sand filter can effectively intercept these impurities and perform preliminary primary filtration.
The sand filter can be used alone. If you want to enhance the filtering effect, multiple sand filters can also be used in parallel.

Hydrocyclone zandafscheider
The distinctive feature of this filter is that it has a cone-shaped tank, with a sand collection tank connected at the bottom. If groundwater is used as the water source in the irrigation area, then the hydrocyclone sand separator is often used during the primary filtration stage.
Since there are fewer floating objects in groundwater, its impurities are mainly sand, stone particles, enz., it is suitable to use the hydrocyclone sand separator, which works based on centrifugal force. The difference in density between water and sand makes it possible to separate them effectively through centrifugal force, achieving the purpose of filtration.

Irrigation Disc Filter
The disc filter is a fine filtration device. Its core filtering component is a stack of plastic circular discs with grooves.
When water enters the filter, these discs are pressed tightly together under the force of elasticity and water pressure, thereby intercepting impurities in the water and achieving the filtering effect. It’s important to note that impurities will accumulate in the discs over time, which may cause clogging and reduce filtration efficiency. Daarom, the discs need to be removed and cleaned regularly to ensure that the disc filter can work properly for a long time.

Irrigation Screen Filter
This type of filter uses a stainless-steel mesh screen as the filtering medium. The mesh has fine openings, so the size of the holes determines the filtration precision. When water flows into the filter, impurities larger than the mesh openings are intercepted, while clean water passes through the mesh and enters the irrigation pipes.
Just like the disc filter, impurities in the mesh should not be allowed to accumulate for a long time. Daarom, the mesh needs to be cleaned regularly to ensure the filter functions properly.

How to Choose a Filter?
In a water-saving irrigation system, primary and secondary filtration are generally used together. When selecting a filter, it is necessary to determine the type and combination of filters based on the type of impurities in the water source.
If there are very few impurities in the water source, then installing just one filter is enough — you can choose a disc filter or a screen filter.
If there are more impurities in the water, with a large amount of suspended matter and quite a bit of sediment, then a combination of a sand filter and a disc filter or screen filter should be used.
If the water source is groundwater, since groundwater rarely contains floating matter, a combination of a hydrocyclone sand separator and a disc filter or screen filter is a good choice.
The above is a general method for selection. In fact, based on the type, concentration, and particle size of the impurities, there are more refined filtering solutions. If you want to learn more, feel free to Neem contact met ons op to consult with a product expert.
Maintenance of Irrigation Filters
The most common problem with irrigation filters is reduced filtration performance (manifested as decreased water output or clogging). This is caused by impurities in the water accumulating inside the filter over long-term use without being cleaned. Over time, this will inevitably increase filtration resistance and affect the irrigation water flow.
Daarom, it is necessary to maintain the filter regularly, which means cleaning the filter element on a regular basis. Generally, there are pressure gauges at the inlet and outlet of the filter. You can determine whether the filter needs cleaning based on the pressure difference.
In addition, many filters come with a backflushing function. There’s no need to remove the filter element — the internal parts can be cleaned using reverse water flow, and the impurities will be discharged through the drain outlet, which is very convenient.
