Water Softeners

Between the different types of water filters that are usually fitted in homes, there is one which is of great importance to avoid possible disorders to health, due to the existence of the so-called water hardness, is that of the softenersalso known as softening water, as well as water softener, the process of eliminating the above.


The water that we consume every day and coming out of the sink, usually contains small concentrations of salts, usually from magnesium and calcium, which with the passage of time tend to accumulate in the pipe and block them, or damaging some artifacts such as faucets.
This obstruction in pipes of hot water that in the of cold water, taking as examples the obstructions in coffee or water heaters, is more common because mentioned minerals salts tend to adhere to the walls of the resistance and the heat sources necessary for the operation.
This brings also a galvanized metal walls of the older pipes tend to a greater corrosion in the presence of these minerals, by the formation of the metal ions, which easily react with ions provided by salts.
The softeners that are marketed are divided into three large groups:
Catalytic: uses a special alloy of metals and generates turbulence and changes of pressure in the water, precipitating Calcium carbonate by a change in the pH of the water, making the crystals of calcium decreasing its size and therefore do not form Tartar or inlays.Mechanics: those used in Osmósis reverse, applying pressure and using a semi-impermeable membrane processes.Chemical: They seek the destruction of minerals with the use of a filter in the form of zeolite cartridge replacing ions of calcium and magnesium by ions of sodium or potassium, which not only does not adhere to the walls of the pipeor it falls with the SOAP. Change the filter is necessary to regularly.

Amantide Electric Trike

One of the more problematic has been generated in recent times is the transport, relating not only to infrastructure problems, but also to fossil fuels, a form of non-renewable energy that not only escaseará in the next few years, but will not apply measures to counterbalance excessive use, generate its exhaustion in the coming years.


That is why different designers and researchers to continue with the development of new Concept and prototypes that will seek to replace the car for a form of mobility of the morning, which initially will be for electric cars, and in the more distant future it will aim at single-seat vehicle similar to a wheelchair.

On this occasion, the concept is called amantide electric trike, and basically consists of a kind of tricycle from a little striking design, but that allows to comfortably navigate the city, as well as having a rather than striking detail: after using itYou can fold completely and take up very little space, increasing its portability.
No doubt quite extravagant, is a design that very few brave are encourage to wear, although it continues to be one of the many ideas that are planned for the sake of a future better and free of carbon dioxideemissions
