Water is a vital resource for humans, not only for its consumption, but also for all kinds of industrial processes and production of goods.

Our activity changes its natural state and contaminates it, causing serious environmental damage to rivers and seas and excludes its use for activities such as agriculture. This is why we must ensure the correct treatment of the water so that it can be reused and returned to the environment.

The wastewater treatment consists of a series of physical, chemical and biological processes that eliminate pollutants  from water so that humans can make use of it.

The purification of waste water from towns and cities or industries is undertaken in a Waste Water Treatment Plant (WWTP).

In the WWTP, purification processes  are performed (like those that occur naturally in the river basin) in a concentrated and automated way. 

Below you will find an explanation for each of the different water treatment processes. Each process has a specific objective according to the purification stage.

It is important to note that the composition of the water, circumstances and end use or destination may require variations on conventional water treatments.
