Water reuse and recycling

Search line summary 

Although having care to minimize the chemical products, water and energy consumption during the production process, at the end there are liquid effluents with organic and inorganic products, some difficult to remove (dyes, flame retardants, antistatic, repellents to water and oil, surfactants, salts etc.).

In this line, the behaviour and improvement of the different purification processes in the purification of industrial effluents are studied. We work both in biological processes (activated sludge, membrane bioreactors – MBR, mobile bed reactors – MBBR, etc.) and with physic-chemical processes (coagulation-flocculation, membranes, advanced oxidation electrochemical processes …).

The research focuses mainly on solving the problems of effluents from the textile industry, but also from other industrial sectors such as fine chemicals, detergents, food, etc.
