Reciclatge

           Plantes de reciclatge (English)

Pull the trash to a landfill is the most simple and economical to get rid of it. But you can not throw garbage anywhere, so the land on which a landfill must meet certain conditions:

To take the trash to landfills must pick before.

The garbage trucks that collected in the streets of towns and cities, once crushed, is transported to landfills. Then he throws dirt on top. Some landfills become parks or on artificial ski slopes! also the visual impact disappears.

The problem with these sites is that the garbage to decompose, emitting greenhouse gases like methane. Furthermore, the accumulation of this gas can cause an explosion, so that landfills should be located in well-ventilated.

Waste generated

Industrial waste treatment in the Vallès

Firstly we proceed to its milled and then arranged in rows of eight feet open pit. The heaps are turned over periodically in order of facilitating the oxygenation and avoid its anaerobic fermentation. The turning reaches made ​​up to twice a week while the temperature is maintained around 55 ° C and the moisture content of the row is between 50% and 60%.

Beginning in the third turned the temperature is maintained at 25 ° C indicate that the fermentation has finished. This occurs after three or four weeks.

After another period equivalent is left to heal and ten proceed to refining, to remove any kind of residue that might be left.




Wastewater treatment

The wastewater treatment is a series of physical, chemical and biological processes that are intended to eliminate the physical, chemical and biological water present in the effluent of human use.


wastewater treatment begins with the initial physics separation of the current large solids industrial or domestic wastewater by using a system of grids then you apply a desanding primary sedimentation followed by an separating the suspended solids present in the wastewater.

To eliminate dissolved metals are used precipitation reactions, which are used to remove principally plumb and phosphorus. Then follows the progressive conversion of the dissolved biological material in a solid biological mass used suitable bacteria. Once the biological mass is separated, the treated water can undergo additional processes.

The final effluent can be downloaded back at a natural water body. The segregated biological solids undergo additional treatment and neutralization
