There are several types of cleaning devices that can be installed in a drilled well. Most types are quite suitable for manufacturing from plastic pipes, especially since such well filters are fully in line with the requirements that are imposed on such products - compactness in combination with high throughput, compliance with the standards of sanitation, resistance to corrosion.
And if you take into account the minimum costs( including temporary ones) when manufacturing a filter from a plastic pipe yourself, then plus such a constructive solution is obvious. How to mount it, what to take into account - and will be the subject of conversation in the article proposed by the reader.
Filter device
There is no sense in getting to work without understanding what the result should be. To give concrete recommendations on linear parameters is meaningless, if only because all the wells differ in cross-section of the pipes installed in them.
And here you need to know the design features of the filter:
- Element of fastening to the pipe - it is often called the "superfilter area".If a plastic pipe is used for production, then the need for such a component part disappears. Why, it becomes clear below.
- Sedimentation tank. As in any filter, there must be a place where solid suspensions that do not pass through the pipe will gradually accumulate.
- Filter itself. In our case, the grid.
filter assembly technology The feature of this filter( in contrast to the filter for the pool) is that it is not a separate structural part, but is manufactured directly on the end of the last pipe assembly bend installed in the barrel. The concrete model is chosen mainly based on the characteristics of the soil and the depth of the well.
In some cases, to increase the performance of the filter, it is possible for him to use a piece of pipe of a larger cross section than the main line that connects to the last bend. Or increase the number of perforations, the dimensions of the holes( slits).
Kinds of self-made filters
Slit
From the name it is clear type of perforation - slits in the walls of the pipe. The scheme of their location is any( symmetrical, asymmetric).The main thing is that they are distributed evenly over the entire area of the filter.
How to make
Markup. With this it is clear - it is necessary to designate places for slots. Chalk, marker, nail( to apply shallow scratches) - everything will do. The lower row of cracks is usually located at a distance no closer than 100 mm to the knee cut. This is due to the fact that during the operation of the well at the bottom will accumulate sludge, which will close part of the end of the pipe.
Slot slot. "Bulgar" is better not to use, as working with it requires a lot of experience. The most suitable tool is a hacksaw( for metal) or a trihedral file. It will be a little longer, but accuracy and accuracy are guaranteed. The length of the slots is selected according to the cross-section of the pipe in the recommended interval of 20 to 70 mm.
Filter design option
Installing the filter element. Once the basis is a plastic pipe, it is advisable to install the grid from the same material. To fix it will be simple - by gluing, good, compositions that do not dissolve, do not soften in water, enough. This will eliminate the need to engage in the installation of additional clamps, various twists, soldering or other technological operations.
Fitting the plug. Water must enter the pipe only through the filter element and the slots. Accordingly, the end of the knee must be tightly closed. What to use, it is easy to think - a wooden "chop", for example.
Perforated filter
Drilling holes in the walls of plastic at home is quite difficult, so as an option for self-manufacturing, this model is used less often. The technology is the same, the difference is in the holes.
There are other types of filters that can be used in the arrangement of a well using plastic pipes. As such, the individual elements are not mounted. Filtration of the liquid is made through the filling - gravel, small gravel( crushed stone).It should only be noted that the quality of water in this way of cleaning will be somewhat lower. But if it is not initially contaminated, then, as an option, you can try.
