Nitrate pollution

The dispersions of the sewage system, the lack of or insufficient maintenance of the aqueducts, the irregular disposal of zootechnical sewage and the excessive use of nitrogen fertilizers are some of the main causes of nitrate pollution of drinking water. Human consumption of polluted and / or contaminated water can cause serious toxicological problems for the body.
Nitrates within the human body react and combine with amines and amino acids resulting in potentially carcinogenic or mutagenic substances. In addition, nitrates can cause hemoglobin to change in methaemoglobin, resulting in reduced oxygen circulating in the bloodstream.
What are nitrates
Nitrates (NO3) and nitrites (NO2) are substances composed of nitrogen (N) and oxygen (O) normally present in nature. They are essential elements for the growth of plants that synthesize their protein structure by exploiting sunlight and soil nitrogen.
The danger comes from the extensive and intensive use of fertilizers – natural and chemical – which causes an excess of nitrates in the soil, in food (especially fruit and vegetables) and in groundwater. When nitrates reach the body through food and water, they become substances that are extremely harmful to human health.
With the integrated separation technology purification plants distributed and installed by A.A Group, it is possible to eliminate nitrates from the drinking water of the network. The semipermeable membranes of which the implants are equipped, having holes measured under a microscope of a size of one millionth of a millimeter (0.0001 micron), are able to retain and separate the nitrate particles of much greater dimensions between 60 and 300 millionths of a millimeter.
