Water distiller

Aquadistillator is a device whose function is to purify water from harmful substances. Distillation is a very similar principle of the natural cycle of water - evaporation and condensation. Most distillers combine steam distillation with filtration after carbonation, which ensures optimum purity of water. With the help of water distiller you can save on the purchase of expensive bottled water and forget about carrying heavy bottles.

Types of water

Groundwater: water contained in groundwater aquifers that reach the surface through springs, deep wells and artesian wells.

Surface water: water collected in the form of rain and snow, and seepage of groundwater collected in reservoirs, lakes and rivers.

Spring water: groundwater that rises to the surface through a natural hole.

Artesian well: groundwater that is reached by drilling and then flows naturally to the surface.

Mineral water: bottled water containing at least 250 parts per million of all dissolved solids. Mineral water differs from other types of bottled water by a constant level and relative proportions of mineral trace elements from the moment they come from a source. No minerals can be added to this product.

Deep water: groundwater that is reached by drilling and then pumped to the surface.

Hard water: water high in calcium and magnesium.

Soft water: water low in calcium and magnesium. Soft water can occur naturally or be achieved by ion exchange, when calcium and magnesium ions are exchanged for sodium ions.

Water through reverse osmosis: the process of reducing the mineral content of water by forcing water through a semipermeable membrane.

Water through carbon filtration: a method for removing organic matter and chlorine using the natural ability of carbon to absorb such chemicals.

Water through deionization: a method of obtaining purified water, the method of removal of inorganic impurities with ionic charges.

Distilled water

Distilled water is widely used not only at home, but also in chemical laboratories, pharmacies, car batteries and many other places.

Distilled water is water in which many of its impurities are removed by distillation. Distillation involves boiling water and then condensing the steam into a clean container. Such water is a better choice than ordinary tap water. Tap water may contain a number of impurities, including:

  • chlorine (and by-products);
  • fluoride;
  • pesticides;
  • fertilizers (e.g. nitrates);
  • heavy metals;
  • radioactive substances (such as radium);
  • microorganisms (bacteria, fungi, parasites).

Filtration with a water distiller reduces these impurities and improves the taste of tap water.

Distilled water is very soft. Therefore, when used in everyday life, kitchen appliances will not suffer from scale, and tea will get a much better taste. For example, irons will last longer if they are filled with distilled water.

Maintenance of water distiller

Maintenance of water distiller includes several steps that need to be done systematically in order to constantly get clean water:

  1. Filter replacement: all domestic water distillers require periodic replacement of the carbon filter. A carbon filter is responsible for removing gaseous and liquid chemicals from distilled water.
  2. Boiler cleaning: water distillers remove all types of inorganic salts, such as calcium, magnesium, etc. This inorganic residue is deposited in the chamber of the distiller. As the residue becomes more concentrated, it accumulates on the surface of the boiler and heating element. Periodic cleaning of the boiling chamber from loose particles, as well as any remaining liquid residue, reduces the amount of cleaning required.
  3. Every few weeks, the boiler may need to be cleaned with either distilled white vinegar or powdered products such as sulfamic acid and citric acid. Do not use abrasive materials for cleaning. It is necessary to avoid the use of sharp objects.
  4. Steam sterilization: all air-cooled distillation systems allow periodic steam sterilization of the cooling and storage system. To do this, you must completely drain the liquid from the storage tank for distilled water and put the control valve on the tank in the "open" mode.

Filter types

All "periodic" or "manual" distillers use some type of "post-filter" - a filter located after the distillation process. Since these types of distillers cannot be connected to a pressurized inlet water source, an inlet carbon filter is impractical.

Fully automatic water distillers, which can be attached to a pressurized water supply source, usually have some kind of "pre-filtration". The system filters organic and volatile chemicals from the incoming water before the distillation process.

Other distillers use both a carbon prefilter and a postfilter.

From a technical point of view, the purity of the water, the most effective place for a carbon filter is the place before the distillation process. There are several reasons for this:

  • in all types of water purification systems, successive sets of equipment are designed to improve water quality, the sequence of placing the filter before the distillation process is important because the carbon filter is less efficient than distillation;
  • it is known that carbon has a tendency to disperse into small parts when water passes through the device if a carbon post-filter is used, and therefore small amounts of carbon can enter distilled water;
  • carbon is known to be an active breeding ground for bacteria if the carbon filter remains moist and exposed to air, so placing it before the distillation process helps to avoid the possibility of bacteria multiplying in the filter.

Extra care should also be taken to periodically sterilize or disinfect the container for distilled water. This is usually done with a small amount of a 3% hydrogen peroxide solution.

Mistakes about distilled water

Does distilled water “leach” minerals out of the body?

This is perhaps the most erroneous and misleading statement that can be heard about distilled water. There are various types of water that can cause serious harm to the body. One of these types is deionized water. Deionized water is commonly used in the electronics industry for cleaning computer circuit boards, and its use is carefully protected in these installations with signs. The inscription on the label usually reads: "Danger - deionized water - for industrial use only." There is no scientifically based literature confirming that distilled water “leaches” any type of mineral or tissue material from the body or its cells.

Some people say that distillers cannot completely remove the toxic chemicals in the water. Is this true or not?

Since the mid-1970s, domestic water distillers included volatile organic chemical (VOC) "air vents" or used various types of carbon filters to remove these substances. VOC air vents were installed directly in front of the condensation coils and were intended to release low-temperature organic chemicals into the air, which made it possible to exclude them from the final product of distilled water. Over time, carbon filters have proven to be more effective than VOC when removing a wider range of substances. Today, all distillation systems include some type of carbon “pre-filtration” or “post-filter”.

People who claim that distillation systems do not remove toxic substances, either do not fully know the basic technology of water treatment, or are simply dishonest with respect to systems that they cannot advertise or sell.

Some sources indicate that distilled water becomes acidic because it absorbs carbon dioxide from the air. It's true?

Any type of water stored in an open container absorbs air gases. If you put an open container of water in the refrigerator during the day, you can feel all the smells of other fruits, vegetables and meat stored in the refrigerator.

Distilled water should be stored in closed containers, like any other drinking water. In distillation systems using hermetic storage tanks, there is virtually no contact with moving air, which may contain carbon dioxide or other airborne organic material. The water remaining in these distillation storage tanks will tend to a more neutral pH.
