According to opinion polls around the world, limescale is perceived as a leading pollutant in water.

The components of limescale (calcium and magnesium) are necessary for human health and give you the taste of drinking water.

Lack of calcium as well as magnesium lowers the pH and puts water into corrosive areas and leads to both health damage and accelerated wear in the pipes and heating elements.

The magnesium that is perceived as a component that produces scale is essential and even necessary for the human body. The advantage of magnesium is that the temperature range in which it sinks is over 100 degrees relative to calcium that sinks already at

65 degrees. However, scale that coats water pipes and heaters produces huge damage estimated in billions every year.


The accumulation of scale on heating elements and heat exchangers of all kinds causes overheating due to the layers of scale and constitutes thermal insulation and unnecessary energy waste at levels of 10% and above.

The piping is clogged and the replacement costs cause high expenses and unnecessary awkwardness, especially since the piping is located in an inaccessible place, and until the decision is made about the replacement suffers from low sufficiency and pressure and hence energy waste as well as valuable time. That after the galvanizing layer is washed (which pollutes itself due to the heavy metals that make up the galvanizing coating) melting of the metal pipes can occur and cause the phenomenon of red water which interferes with the aesthetics of water use and in addition, damages the taste qualities of water as well as odor. The processes of preventing damage from scale as well as preserving the values ​​of important minerals are actually carried out by the products of Dropa Tech in every flow and in every diameter.

Softening the water – leaving  scale and its derivatives with the help of resins (resins) that produce ion exchange, there is a law that prohibits the installation of “ion exchanger” because the water harms both health and creates salinity to underground aquifers. When the resin is saturated with scale, a “refresh” procedure must be performed by draining the brine.

Advantages: Get high flow and excellent water pool results.

Disadvantages: The treatment that requires suffering from sacks of salt, the water is not suitable for drinking. Causes of: Reds ”, water that especially attacks iron and copper, it is important to prepare pipes that are not sensitive to acidic water and it is better before installing a softener, preferably stainless steel or plastic pipes.

Desalination – There are several techniques, the leading of which is the reverse osmosis, in this method water is transferred into a

semi-permeable membrane and thus the variety of dissolved substances remains outside.

Advantages: Reducing all levels of solutes, including derivatives of scale, capable of sweetening seawater, getting rid of organic pollutants, dissolved gases, bacteria, and viruses.

Disadvantages: expensive costs, very low flow and therefore it is mandatory to install a tank for collecting the water at the end of the process, the water is acidic and tasteless and difficult to drink, it is better to balance the reaction ratio.

Water collection must be carefully handled to prevent a “microbial outbreak.”

Evaporation – an expensive and cumbersome process that requires a lot of energy.

Advantages – the equipment is cheap, high availability for everyone, the water is high quality without salts but not drinkable.

Disadvantages – the water production process is expensive and the production quantities are small.

Rainwater – collecting the rainwater into reservoirs.
Advantages – availability, cheap price, excellent for washing purposes, steam iron, dishwasher, and washing machine.
