The importance of water purification

Human activity is responsible for a high consumption of water every day. The consequence is the production of a significant quantity of wastewater, which before being reintroduced into the environment must be subjected to purification treatments. 

This process, regulated by a series of national and community regulations, is fundamental for the well-being of the planet because it prevents chemical substances from ending up polluting ecosystems.

Wastewater: Why is purification an indispensable process?

Waste water from the civil and industrial sectors is full of chemical compounds of synthetic origin. Generally speaking, thanks to a series of natural filters and biological processes, seas, rivers and lakes have a certain self-purifying capacity: a capacity that is completely insufficient if the waste water contains high quantities of dangerous substances.

In fact, any discharge of waste into water bodies would risk compromising the quality of the water present, loading seas, rivers and lakes with complex pollutants difficult to dispose of and harmful to the balance of ecosystemsPurification allows waste water to be subjected to treatment systems similar to those that occur in nature, but in a more efficient way and with significantly shorter timescales, safeguarding the harmony of the receiving water bodies and consequently the quality of water present in nature.

At the basis of this process, the purification plants, in which waste water is conveyed to be subjected to chemical, physical and biological processes aimed at eliminating pollutants. Of course, today there are different types of purification plants, sized according to a series of parameters, including the hydraulic load and the quantity of pollutants present in the waste water.

Companies such as GAZEBO SpA that designs and builds innovative and high-tech purification plants: on the GAZEBO website the most innovative ones are illustrated in particular solutions for the purification of civil and industrial wastewater, for the first rain water treatment and the lifting and pumping stations, all carefully constructed with latest generation prefabricated monoblock tanks in reinforced concrete.

Wastewater Treatment: The Importance of the Purifier

A purification plant is composed of a series of artifacts designed to treat water through a wide range of functions. Within a system of this type, two specific processes can be distinguished, the water line e the mud line, the first designated for the purification of water coming from the sewerage system, the second reserved for the treatment of sludge resulting from previous processes.

Both procedures, of course, are of fundamental importance, as they are decisive in the process of reduction of the percentage of dissolved or suspended substances considered incompatible with a biological purification process.

The water line, in particular, is carried out through three processes: a primary treatment di physical type, secondary treatment di biological type and a tertiary treatment capable of further refining the purification process.

The primary treatment, more specifically, includes operations of grilling, sandblasting, degreasing e primary sedimentation aimed at removing suspended sedimentable particles present within the sewage. The secondary treatment, which is perfected with theaeration , secondary sedimentation -both aimed at eliminating sedimentable and non-sedimentable substances- precedes the tertiary treatment, which removes all those substances not eliminated by the previous treatments. The final phase instead includes the sludge line, which reduces and stabilizes the volume of the residue or organic.

This is how wastewater treatment allows waters that have wastewater values within the limits of the parameters imposed by the legislation, protecting ecosystems from the harmful effects deriving from a potential water pollution. 

Valuable in industry, especially with regard to waste reduction andIncreased productivity, wastewater treatment is subject to constant improvements in treatment processes: an evolution that could favor a progressive increase in the workforce and guarantee a plausible solution in the event of a water crisis.
