Do not know why you need a well screen for the filter and the filter itself, and also how to choose such a product? Further we will help you deal with these, and many other similar questions.
When a well needs a filter and what are its functions?
Traditionally, all well filters have two main functions:
- First, such products provide water supply, free from various mechanical impurities;
- Secondly, the filters also prevent the collapse of the well, which, you must agree, is important.
As usual, filters for wells are installed only if it is a question of so-called unstable rocks.
Recall that here about any natural filtering of speech does not go, in the form of permeable solid ground.
In the design plan, any wellbore filter will consist of three parts: a working part( that is, directly, the filter itself), a settler with a stopper, and a superfilter tube.

The same in all cases and the process of filtering.
So, those parts of the rock, for which the screen for the well filter did not become a hindrance, settle in the settler and only then, clean water without them is delivered to the consumer.
Types and designs of well filters
If you decide to buy a filter for a well, it will be useful for you to know that all such products today are divided into three different types: gravel or gravity, mesh, as well as perforated or slotted.
When choosing the types and design of filters, it is worthwhile to pay attention to the type of well in which the well was created.
So, for those corrosive rocks containing a large amount of hydrogen sulphide, oxygen or carbon dioxide, it is appropriate to use models whose frame is made of stainless steel or non-metallic pipes.
Perforated and slotted filters are of current use for fractured rocks prone to collapse. In this case, the slots in the pipes are suitable for milling, and the holes for drilling.
Filters for wells drilled in gravel-pebbly deposits are usually made of pipes that have either longitudinal slots or a grid of large cells.

And here for the sands it is worth to purchase those filters that have a coating in the form of a brass grid with sufficiently small cells.
We hope that we could be of use to you and now you can easily and quickly select the type of filter that best fits your well and ensure you a clean water supply for a long time.
