PROJECT FEUP/CCDRN/2006/2 - "TREATMENT OF RIO MEÃO AQUIFERS CONTAMINATED WITH TRICHLOROETHYLENE"

The main objective is the mediation of two aquifers contaminated with trichloroethylene located at Rio Meão. This volatile organic compound will be eliminated either by pumping the groundwater to the surface and treating it by Air Stripping, either by its destruction or transformation at its location (in-situ). The target concentration for the remediation will be fixed according to the limits imposed within the European Community for groundwater (document under preparation). For the Air Stripping alternative the process will be designed in order to minimize the operating cost. The project includes the selection of the equipment as well as operatory technical assistance. In the second alternative batch laboratory tests in columns will be performed in order to chose the most appropriate reactant: either an oxidante or a deshalogenator. The results will be used to select the most appropriate reactant according to the following criteria: final concentrations, costs and kinetics. This alternative will be compared to the previous. For the final selected alternative a project will be performed including the preparation of reactants, the injection system (number of holes, its constitution, location, flowrates, …) as well as the definition of a complete monitoring system.
