Filters for groundwater wells

Many people think that groundwater is clean and safe to drink.
But this is a myth

Water from a groundwater well is way better than well water: it does not contain organic impurities, and bacteria are less common there. But the groundwater well has its drawbacks: increased content of iron, hardness salts, manganese, hydrogen sulfide.

Iron

Iron often affects the quality of water from a groundwater well. Its maximum concentration has to be no more than 0.3 mg/l: if it is higher, water will taste bad. Also, in this case iron bacteria will spread, that means plumbing equipment and clothes after washing will be covered in yellow stains.

Hardness

Water hardness is another common issue for a groundwater well. Water is considered hard if the content of calcium and magnesium salts exceeds 2–3 mEq/L. Hard water leads to the scale build-up in kettles, boilers and washing machines. Besides, soap, shampoo and washing powder would not foam well.

Hydrogen sulfide

Hydrogen sulfide is more and more often found in groundwater wells. The repulsive smell is not its only drawback — it also causes corrosion of copper, steel and brass items. Hydrogen sulphide is a toxic compound, and the water containing it is not potable.

Manganese

The normal amount of manganese in water is 0.1 mg/l. If the concentration is higher, water gets a bad taste, stains appear on household appliances and washed clothes. Increased amount of manganese is bad for your nervous system.

AQUAPHOR water filtration and treatment systems solve a problem of contaminated water from a groundwater well.

If you want your water to have a balanced composition, you need to choose the right water filtration system.

This requires a chemical analysis of water from the groundwater well. We can perform an in-house analysis of your water, taking into account all important parameters — the number of residents, water consumption rate, the groundwater well depth.

Standard solutions

How do you remove iron from groundwater?

To remove iron from water, we recommend you to install a filter with ion-exchange resin. As the water passes through this resin, the dissolved iron ions are replaced by sodium ions.

AQUAPHOR S series iron removal systems work on this principle. They are suitable for treating iron-rich well water provided that the iron concentration does not exceed 14 mg/L. Reverse osmosis systems are also highly effective at removing iron from water. In addition to iron, they remove bacteria, viruses, chlorine, heavy metals, pesticides, organic impurities, nitrates, and nitrites.

How do you remove sand and silt from water?

To remove sand from groundwater, use mechanical filters. They are designed for pre-filtration and come in two types: those with cartridges and those with a mesh. In a cartridge filter, water is purified by passing through a replaceable cartridge. A mesh filter traps sand particles using a fine mesh screen.

For pre-filtration, we recommend you to install AQUAPHOR Gross 20 filter: it removes sand, silt, rust and other particles up to 10 microns.

How can groundwater be softened?

Ion-exchange filters for limescale removal are well suited for water softening, for example AQUAPHOR S550, S800, or S1000 systems. They provide comprehensive treatment by reducing manganese, iron, and hardness salts.

AQUAPHOR softeners are designed for treating hard, or “limescale-rich,” water from all types of wells, including artesian wells.

See the catalogue of softeners.

How do you get rid of an unpleasant water smell?

The problem can be solved by installation of a special filter for purification of groundwater and removal of smell.

AQUAPHOR Gross is designed for fine filtration. It removes unpleasant odor, heavy metals, organic compounds and trace contaminants. The filter cartridge is a mixture of activated coconut shell carbon and AQUALEN fiber. For effective filter operation, you need to replace cartridge according to the schedule.

Do I need to remove calcium from the water?

Calcium is an essential element for the normal functioning of the body. However, firstly, calcium from water is not absorbed effectively, and secondly, it can damage household appliances. Boilers, pipes, and water-heating elements can have a much shorter service life in hard water. Softening well water is therefore one of the most important tasks when organizing a water supply system for a house or property.

AQUAPHOR water treatment systems remove hardness salts and effectively soften the water, significantly extending the service life of expensive household appliances and plumbing.

Water from my groundwater well is turbid. What should I do?

Cloudy water can be caused by sand, high iron content, damage to the well filter, or chemical contamination. Water from a shallow well may also become cloudy because of microscopic algae and bacteria. To determine the exact cause, we recommend carrying out a comprehensive water analysis.

A good solution for a country house or cottage is to install deep-treatment sorption filters with activated carbon or reverse osmosis systems. For rusty and cloudy water with a high concentration of large particles, additional main-line filters may be required, as they are suitable for treating large volumes of water.
