Nowadays (with an absolutely unsatisfactory environmental situation), many citizens most often think about what they eat, drink and how they breathe. Since the availability of demand in the market generates supply, it is not surprising that there are many cleaning devices offered to customers. One of the first places is occupied by filters for water purification from a well. This is explained by the fact that these filters purify water from a variety of contaminants (insoluble heavy metals, chemicals), as well as disinfect water from viruses and bacteria.
Filters for cleaning water from a well are an essential part of a
well design, the durability and quality of which depend on the correct choice of filter type and size. The life of this device during uninterrupted operation is 5 to 7 years.
Filters for cleaning water from a well usually consist of elements such as a filtering (working) part, a sump and a filter tube. This unit transmits water into the well from sand (the least resistance to water inlet should be the least), and also prevents collapse of the walls of the well.
During application, the surface of the specified filter becomes clogged, since grains of sand settle on its inlet and get stuck in them. Also, over time, this device is exposed to corrosion, inevitable is the precipitation of various chemicals, which are mainly compounds such as iron, magnesium and calcium. With these precipitations, the grid is covered, as a result of which the distance between the pipe and this grid becomes clogged, and the inlet openings are also blocked. Because of this, it is necessary to periodically clean the wells and replace the filter elements.
To create a zone with greater water permeability, stationary filters for water purification are usually covered with gravel sprinkling, which also provides an increase in the inlet openings and the presence of favorable conditions for the working process.
When choosing these filtering systems, it is necessary to take into account the composition of the rocks in which they will be:
- for rock prone to collapse, filters for purifying water from a well are made of pipes that have holes and slots;
- for pebble and gravel rocks, said water treatment systems are made of pipes that are coated with a large mesh or have longitudinal gaps;
- for sandy rocks, industrial filters are used for water purification with small brass nets, for the selection of which sifting of dry sand is carried out through them: the mesh that passes 50% of the bulk substance is suitable.
To determine the composition of the rocks, it is necessary when taking a well to take a soil sample for the study.
To ensure a better choice and establishment of these water treatment systems, you should contact specialists in this type of activity.
