“Water and sanitation are one of the main drivers of public health. I often refer to them as “Health 101″, which means that once we can secure access to clean water and proper for all health facilities, regardless of the difference in their living conditions, they have won a major battle against all kinds of diseases. ” “Dr LEE Jong-wook, Director General, World Health Organization.”

1. Water Purification

For the distribution of water in cities and communities, it must be fit for human consumption (drinking), so it must be treated with specific measures to thereby purifying the water to reach the quality standards required today.

2. Desalination plants

In many regions the use of sea water, either as a drink for humans or for fields as irrigation for agriculture and forestry no longer be necessary; for the use of sea water or salt water, it is necessary to remove salt from water by desalination processes, using technology such as the reverse osmosis being the most advanced, efficient and less harmful practice with the environment .

3. Plants for sewage treatment

The sewage treatment is a series of physical, chemical and biological processes aimed at eliminating the physical, chemical and biological contaminants in the effluent water for human use.

To reduce pollution from sewage from the cities, the product of human or industrial use, it is necessary to treat them as prior to being discharged into rivers and thus use normal step.

Traditional (obsolete) systems for the wastewater treatment, as the case of “impoundment” gases generated due to organic decomposition, along with the amount of disease-causing microorganisms that are present, without leachate that deterior√°ndola seep into the ground and may even contaminate underground aqueducts.

Anaerobic digestion is a biological process in which the material in the absence of oxygen, and by the action of a group of specific organic bacteria, or decomposes into gaseous products “biogas” and digestate, which is a mixture of mineral products and compounds of difficult degradation.
