Bottom filter well with their hands

word "well" is associated with cold, clean and tasty water.But sometimes the water in the well does not live up to expectations - it is a cloudy, opaque, and after standing, the precipitate gives an unpleasant color and odor.To filter this water does not need to install expensive purification system is often used for centuries proven method - the bottom of the filter natural materials stacked on the bottom of the well in a certain sequence.

bottom filter if necessary?

To determine whether your filter needs the well bottom, it is necessary to examine the bottom and define a breed that it generates, as well as the direction of the water-bearing veins.This can be done as in the digging of the well, as well as during routine cleaning, if you are dissatisfied with the quality of water.There are several cases:

  1. bottom of the dense clay with gushing springs from it.The water is clean, the rock that forms the bottom is not dissolved.Such a well is not needed in the bottom filter, furthermore, the bottom filter may harm in this case by closing springs at the bottom.The coarse filter accidentally fallen into the water particles to better implement, install a filter in the water intake system.
  2. bottom of soft clay, eroding active water flow.In this pit in the bottom of the water is murky.If the height of water in the well is significant water from the upper water layer may be performed without filtering.But it is better to lay on the bottom layer of large gravel thickness of 15-20 cm, it will prevent the active erosion of the bottom.
  3. Sandy bottom, the water is not in full swing, but calmly and evenly seep into the well.This requires a well in the bottom filter - in its absence, the sand on the bottom of the well will be instantly eroded in any impact, for example, when the bucket hitting the water or bottom of the well.Putting pumping equipment in a well the more impossible - Troubled from the bottom of the sand instantly score system and can cause pump failure.

floaters on the bottom of the well.Floaters - is sand, to limit saturated with groundwater, while he acquires the fluidity inherent in liquids.Visually, it can be recognized by the cloudy water jets or periodic emissions at the bottom of the well.To get clean clear water, in which the well will not only arrange the bottom filter, but also protect it from erosion of a wooden shield.

way, how to purify water in the well, we have already mentioned above.

materials to bottom of the filter device, the description and preparation of

  • grained quartz sand.Find it can be found along the river banks.Silica sand has a grain size up to 1 mm, with fine inclusions translucent dark color.Sand before laying in the pit should be cleaned: put a layer of sand in a container, add water, stir and leave for 20-30 seconds, then drain the water.Heavy large sand particles will settle during this time, and the clay and silt residues remain suspended in the water.This procedure can be repeated several times until the water from the sand does not become substantially pure.

  • river pebbles.Like sand, found along rivers in the form of stones of different sizes and colors of round shape.Pebbles - Natural chemically neutral material, the normal background radiation.Pebbles before laying down the well just need to wash under running water.

  • Gravel - loose porous sedimentary rock.Gravel grains are of various sizes, from a few millimeters to several centimeters.Gravel often has impurities harder rocks, clay or sand.It is also used in drainage systems.You can not take the gravel used in other systems - due to the porosity of the material capable of storing a variety of dangerous contamination.

  • Rubble.Irregularly shaped stones of various sizes are produced mechanically.Can be of various minerals.For the bottom of the filter device it is not for every gravel.Building rubble of limestone dusts and contaminate the water, and eroded by prolonged contact with it.Granite chippings are not suitable - it has increased radiation background.For the bottom of the filter is recommended to take the rubble of neutral minerals that have the ability to purify water, such as jadeite.You can purchase it in stores that sell bath accessories - this stone is most popular for sauna ovens.

  • Shungite or petrified oil.It is used in water purification systems to remove it from heavy metal compounds, organic impurities and oil.If the well is located near businesses or roads, or the depth of the well is less than 5 meters, will allow the addition of schungite disinfect it.

bottom Filter Types

Bottom filters by the method of stacking are of two types:

  • straight;
  • reverse.

Straight bottom filter with the laying of a larger fraction at the bottom of the well.It is used in two cases: if the bottom of the well is made up of loose clay, either during installation of the bottom panel of the floaters.Reverse filter means laying on the bottom of a fine-grained fraction.It is used in wells with a sandy bottom and calm duct.

Fitted bottom sheet filter

Shield used in the case of risk of floaters.It is made of hardwood that can be stored for a long time in water: aspen or oak.Shield knock together from boards, cut to the size of the well bore, drilled holes in it with a diameter of 1 cm, wrapped with geotextile and lowered to the bottom.To shield has raised the water flows, it is laid a layer of large stones, and after sleep small pebbles or gravel layer of at least 15-20 cm. In the case of large floaters shield gradually sucked into the sand, so every five to seven years it will have to be installed again.

task filter in this case - not only filter the water, how to prevent its erosion.At the bottom of the well, cleaned of dirt and mud, put a layer of gravel or large stones, put a second layer of gravel with a grain size in 5-6 times lower than the first layer, and the top is filled shallow river pebbles.The thickness of each layer should not be less than 15 cm, that is, the entire filter will take about half a meter depth of the well.

Reverse bottom filter to the well with a sandy bottom

return filter has a dual function - does not allow the particles of sand to climb the top under the influence of jets of water or mechanical impacts and at the same time it protects the bottom of the well from the large collection, accidentally fallen into the well.

Carry it in reverse order.First, at the bottom of the stack purified layer of river sand, pre-washed.Next layer - shungite river gravel or grit size fraction up to 1 cm last layer -. Crushed stone or stones with a size of 5 cm thickness of each layer, as in the case of the direct filter, not less than 15 cm

Wall..filter of coarse concrete

if the water flow at the bottom of small, sometimes it is necessary to arrange additional wall filters to fill the well was going well through the walls.To do this horizontal hole, ascending or V-shaped, in which the coarse filter is mounted in the lower concrete ring.Preparing concrete from cement and gravel without the addition of sand.Cement is diluted with water to a consistency of sour cream, and then pour them gravel and stones enveloping stirred to solution.The resulting mixture was packed into prepared holes, and are waiting for concrete curing.gravel size is selected according to local conditions, it must be such that the filtered sand.

maintenance and care of the bottom filter

In operation, the bottom filter clogged with particles of silt, clay and sand, and needs to be cleaned annually.Stones being removed from the wells and washed with pure water, completely replace the sand, and then placed on the filter bottom in the same sequence.

Such uncomplicated and inexpensive device as a bottom filter helps you to purify water in virtually any pit and make it suitable for household needs.For drinking water may be used only after a positive result of the analysis, which is done by the specialists of SES.Bottom filter will protect the well from siltation and growth of microorganisms, as well as extend the life of the pump equipment.
