In most cases, a well is made for the construction of an autonomous water supply at a dacha. So that she can give clean water for a long time, care should be taken to prepare the filter for the well. It will be immersed in the aquifer, so its quality must be appropriate. In this article we will explain how to make a filter for the well with your own hands.
Example of a plastic slotted filter
A filter for a well is an element located at the very bottom of the casing. In some cases, it is called a work site. It performs an important function of preventing the entry of soil particles into the structure, through which clean water flows to the surface. In addition, it provides additional protection against collapse. Making filters is carried out in several ways. In this article we will discuss with you the following filters that everyone can make:
In an artesian well
Speaking about perforated filters, their design is most popular. In their structure, they resemble the usual perforated pipe, which is covered with a grid. Make it yourself is easy. The most important advantage of such a filter is high efficiency. Also perforated perforated filter is applicable in a variety of rocks. It is used in most cases in the manufacture of artesian wells. The construction itself has the following components:
As regards the last section, large particles accumulate in the sump. It is located at the very bottom of the trunk.
You must first prepare the following construction material and tools:
Grid selection can be performed by sieving sand from an aquifer. So, a grid that passes 50% of the sand will be the most suitable.
Making a filter with plastic perforations
The filter manufacturing process itself takes place in such sequences:
So, the perforated filter for the well is ready!
If in your case a rock predominates in the well that is prone to collapse, then a slot filter will be the best option. Its main feature is that it has sufficient bandwidth. On top of the product there is no deaf zone, and the area of the gap exceeds the area of the hole. To be objective, this design has one drawback. The slotted filter has a slight bending strength. For this reason, in the process of its manufacture, it is necessary to create stiffening belts that will not have perforations.
You will need the following building materials and tools:
The principle of manufacturing a slotted filter is similar to the principle of manufacturing a perforated filter. The slots must be made in the zone order or in chess. The size of the gap is determined by the diameter of the granules, which predominate in the composition of the rock. As in the first case, the pipe must be wound with a brass mesh of brass weaving. Preliminarily, with the help of a grinder and a cutting wheel, make slots in the pipe. Before you lay the grid on the pipe, it is necessary to wind the wire in 2 cm increments in a spiral. It is recommended to solder the wire at a distance of 0.5 meters, which will allow you to make a rigid structure.The self-made slotted filter, made by this technology, is quite durable and has good throughput.
For better structural strength, the mesh can be soldered to the wire.
Speaking of simplicity then this type of filter belongs to this category. At the same time, the gravel filtration construction will be no less effective than the above described filters. So, to make it, you need to take the following steps:
The average size of rock fractions should be less than ten times the gravel fractions.
The gravel filtration system is ready for use.
