Hormones in drinking water
Original language description
Drinking water in the Czech Republic is mostly prepared from the surface water. The corresponding technology is mostly based on sedimentation of solid particles, coagulation by addition of ferric sulphate, removal of precipitate containing impurities like colloid substances of organic origin (humic compounds, peptides, soaps etc.) as well as inorganic compounds (clay particles too small to be removed by sedimentation, precipitates). The next step is deacidification by aeration or by addition of calciumhydroxide, followed by filtration and disinfection by chlorine. This technology is in many cases ineffective for removal of new type pollutants like drug residuals which are present in surface water as result of their incomplete removal during waste water treatment.
