Water Quality and Treatment

Introduction:

The main objective of the work currently being carried out in the research group “Water Quality and Treatment” is the protection against water pollution. The research work aims to minimize and reduce water pollution. The group activity is divided in two areas. First, water and industrial wastewater quality control techniques and secondly, non-conventional treatment techniques applied to the removal of hazardous pollutants from water. Consequently, from an engineering and environmental technology point of view, our research areas focus on water pollution control and natural and wastewater treatment technologies.

Research Lines:
  1. Water pollution control

    This line of research, started in 1980, is based on many research projects funded by the Ministry of Environment in Spain through the Ebro Hydrographic Confederation. The main objective includes the identification of the main activities discharging hazardous pollutants to the Ebro River basin, the characterization of major industrial discharges and the water quality control of both groundwater and surface water.

  2. Water and wastewater treatment technologies

    This research line focuses on the application of advanced oxidation techniques to remove hazardous contaminants from water. These techniques include the use of ozone, combined ozone (along with hydrogen peroxide, high pH, metal catalysts, UV light, sunlight, titanium dioxide), Fenton reagent and photo-Fenton with aeration (homogeneous or heterogeneous phases). All these techniques are combined with conventional techniques such as coagulation-flocculation, adsorption on activated carbon, biological treatment, etc...These techniques can be either applied to water treatment or to industrial wastewater treatment (pesticides, dyes, paper mills, wine making, manufacture of rubber, paints, etc.).
