The current concept of sustainable development applied in solving society's problems requires both the use of ecological materials for water, air and soil depollution and their green chemistry. In this context, the use of renewable materials in the structure of polymeric sorbents has been imposed in recent years. Synthetic and natural polymers are increasingly being used in building materials with high performance structures. The combination of the two categories of polymers can lead to materials that possess both chemical stability and resistance to extreme pH and temperature values specific to synthetic compounds as well as special characteristics of natural polymers (bioadhesiveness, biodegradability, biocompatibility) with increased capacity sorption and improved mechanical properties. This study proposes the development of new solutions that are based on individual or combined unit processes for sequential / simultaneous elimination of priority pollutants (organic and toxic metals). For this purpose, innovative polymeric materials or composites are designed with properties (porosity, shape, size, sorption, selectivity) adapted to the characteristics of treated waters (types and concentrations of pollutants).The study brings novelties and important contributions to advanced water treatment. The proposed technological solutions at the laboratory scale will be tested on the pilot plant. The adaptation and exploitation of a pilot plant for the testing of the selected technological solutions at the laboratory scale is the key link for the technological transfer to the industrial scale for this study.
