Advanced oxidation: a sustainable solution to protect groundwater

Groundwater depletion has become a global concern, threatening access to drinking water and the survival of ecosystems. Advanced oxidation processes, which provide a means of reusing water that has already been exploited or treating groundwater efficiently, are emerging as a promising alternative to temporary solutions such as mega-basins, which impose numerous environmental constraints.

The overexploitation of water resources, the increase of urbanisation and even climate change are all contributing factors to the drying up of groundwater. This is leading to a shortage of drinking water and damage to ecosystems, endangering biodiversity. 
However, many industrial companies rely on large quantities of water to carry out their activities. Sustainable alternative solutions are therefore available to them to preserve this increasingly scarce resource. 
Advanced oxidation processes, for example, use powerful chemical reactions such as the UV/H2O2 reaction to effectively eliminate pollutants present in groundwater, or complement treatment in wastewater treatment plants to obtain water quality that can be adapted to each industrial sector.
These innovative technologies offer effective elimination of organic contaminants, preserving water quality. In addition, they reduce evaporative water losses caused by mega-basins and minimise the generation of toxic by-products. In the long term, these solutions are economically and ecologically sustainable.
Advanced oxidation processes represent a responsible alternative for preserving threatened water tables. These innovative techniques effectively combat the drying up of groundwater reserves while minimising environmental impact.
