In most cases, for the construction of independent water supply in the country is made well.For a long time she could give clean water, it should take care of the preparation for the well filter.It will be shipped in the aquifer, so the quality should be appropriate.In this article, we'll show you how to make a filter for the well with their hands.
filter wells.What is it and what are the types?
example plastic slotted filter
filter is an element of the well, located at the bottom of the casing.In some cases, it is called a work site.It performs an important function to prevent ingress of soil particles inside the structure through which the pure water is supplied to the surface.In addition, it serves as additional protection against collapse.Production of filters is carried out in several ways.In this article we will discuss with you
- filters with perforation,
- slotted filters,
- gravel filtration facility.

Speaking of perforated filters, their construction is the most popular.By their structure they resemble conventional perforated tube which is covered with a net.Make it yourself easy.The most important advantage of such a filter is a high efficiency.Also, perforated filter with perforations applied in various formations.Use it in most cases in the manufacture of boreholes.The structure itself has the following components:
- nadfiltrovy site,
regard to the latter area, the settler is an accumulation of larger particles.It is located at the bottom of the barrel.
You must first prepare the next building material and tools:
- steel pipe of suitable diameter.In some cases, allowed to use plastic pipes, but it is important that the food was plastic.
- Drills for metal.The diameter of the drill should be selected according to the size of the granules, which predominate in the soil.
- Electric drill.
- metal mesh.
Making filter Perforated plastic
very same process of making the filter is held in the following order:
- measure the length of the settler.
- By placing a tube on a flat surface, put on her layout.The perforated area must be 25% of the total length of the pipe.
- Further, the holes are made.From the edge of the tube retreat one meter.Between each opening interval should be 1-2 cm. The holes must be drilled at an angle of 30 ° -60 °.Direction angle upwards.
- Every sharp edge should be thoroughly cleaned.The product obstuchal slightly to the inside and the outside was not swarf.
- The next step closing the wooden stopper bottom of the tube.
- order not to clog the holes, tighten the pipe into the net.

Manufacturing slotted filter
If your case well prevails breed that is prone to collapse, then the best option would be to manufacture the filter slot.Its main feature is that it has sufficient capacity.Top products no hollow area and the area exceeds the area of the slit opening.To be an objective, such a construction has one drawback.Slotted filter has a small bending strength.For this reason, in the manufacturing process necessary to create a belt rigidity which will not have perforations.
you will need the following construction materials and tools:
- cutting torch,
- stainless wire Ø3 mm,
- brass mesh,
- required pipe diameter,
- cutting disc.
slotted filter manufacturing
principle manufacturing slotted filter is similar to the principle of production of perforated filter.The slots must be performed in the waist or in a staggered manner.The size of the gap is determined by the diameter of the granules, which are predominant in the composition of rocks.As in the first case, you need to roll up the tube brass mesh weave braid.Previously using a grinder and cutting disc fabricate cracks in the pipe.Before you apply a grid in the tube, it is necessary to wind the wire in a spiral in steps of 2 cm. At a distance of 0.5 meters is recommended to solder the wires that will make the rigid structure.Homemade slotted filter formed by this technology sufficiently durable and has good capacity.
Gravel filtration facility
If we talk about simplicity, this type of filter fall into this category.In this construction gravel filtration will be no less effective than the above described filters.So, to make it, you need to take the following steps:
- hole wells to be drilled larger diameter.
- Further, calibrated and chosen gravel.The fraction of gravel must be the same size.
- well then filled with gravel, a layer of which should be 5 cm.
Gravel filtration facility ready for use.
