Removal of Pharmaceuticals
Water is the most important resource in the world. However, even though water covers almost 70 percent of the earth’s surface only about 0.007 percent of the earthly supplies of water are directly available to mankind. Therefore, it is particularly important to protect this precious resource from contamination.
The role that especially pharmaceuticals play is not insignificant. Their active agents and decomposition products are secreted by mankind and animals and reach the hydrological cycle via the sewage. In addition to this, expired medicines are disposed of via the toilet. At present, the waste water purification plants are not designed for the removal of these substances or they have long since reached the limit of their capacity.
With the help of the hybrid silica gels investigated within the project Wasser 3.0, a new concept is being developed to cleanse the water of these substances and thus to improve the quality of the water sustainably.
