Water Purification

 


Water PurificationSocial activities (in particular productive and recreational activities), mainly in urban areas, require and use a large amount of water.

The direct consequence of water use is the production of discharges , that, in order to be returned to the environment, must necessarily be subject to a filtering and cleaning treatment.

Urban waste water, which once contained almost exclusively biodegradable substances, are currently the biggest problem as for of disposal due to the increasingly large presence of synthetic chemical compounds, mainly used in industry.

The sea, rivers and lakes are not able to receive an amount of pollutants higher than their self-purification capacity, without compromising the quality of their water and the normal balance of the ecosystem. It 'obvious, therefore, the need to purify waste waters through treatment systems which mimic the biological processes that occur naturally in water elements (water purification, however, is much faster in plants than in waterways, thanks to the technology and energy employed).

The treatment of the wastewater is much more stringent as the receiving water elements (seas, rivers, lakes, etc..) are at risk of permanent pollution. The purification by biological treatment technologies are essentially based on exploiting natural phenomena events played in artificial environments, so that the parameters governing these processes can be controlled optimally.

But the purification consists also in the use of perforated metal sheets, with a high surface area of hollow passage which provide less resistance to water.
