Objectives Practical criteria in the design and maintenance of MAR wells and boreholes in order to minimize clogging impacts, obtained from three different operative sites in Spain
FERNÁNDEZ ESCALANTE, Enrique Tragsa I+D+i
1. Study on the biggest impact that affects MAR facilities: clogging 2. Clogging characterization for three MAR areas in Spain (down-hole techniques, sampling and analysis) 3. Improvements to be applied to wells and bores designs and water pre-treatment criteria 4. Proposal for practical interventions at hoc (cleaning and maintenance operations ) in order to reduce the clogging genesis and to increase the effectiveness of the facilities
