Since all the project is focused on the protection and help to the environment, students, before starting to work in Italy on the Oglio river, went to visit a plant that does a great job in this field, the Verziano depuration system.

This place in addition to the waste water of the city of Brescia, collects almost all of the discharges of a great number of zones near to it.

In the wastewater treatment tanks, the bacteria present transform the biodegradable pollutants into non-polluting substances.

The innovative systems used make it possible to make the water leaving the plant usable in agriculture.

Among other things, the purifier presents an innovative element that has been explained to the students, an ultrafiltration system, called MBR (Membrane BioReactor), which in Brescia had the first large-scale world application for civil wastewater.
