Water is essential for life, pure drinking water is a limited resource and its demand to supply ratio is increasing globally due to population growth, climate change… Development of efficient, sustainable and cost-effective techniques for water purification and reuse is therefore urgent.
Artificial Recharge is an often used technique to replenish exploited aquifers. Water of insufficient quality for drinking is infiltrated via basins or surface spreading through soils and aquifer sediments thereby improving its quality. Although managed recharge has been used for decades, the techniques is often operated as a black box without knowledge of the micro-organisms and the metabolic processes and pathways involved.
ACWAPUR project aims at developing innovative techniques to prevent leaching of pathogens, inorganic nutrients and organic pollutants to underlying aquifers during artificial recharge processes. This will be achieved by the use of advanced treatment permeable barriers, with a porosity that prevent leaching of pathogens and at the same time provide optimal conditions for microbial degradation processes. These barriers are constructed using organic layers to promote sorption of organic pollutants and facilitate the creation of different redox conditions to accelerate aerobic and anaerobic degradation processes.
In this context, we have constructed a group of 6 small recharge basins, combining different plants and barriers compositions to compare the behavior on the contaminants degradation. This seminar it would be formed by two parts: experiment design and first recharge period (lessons learned or not), and first chemical results. Waiting for the analytical results, we left the second part for summer comeback.
