Removal of pharmaceutical products from water in wastewater treatment plants
Hamanová, Sabina ; Fuksa, Josef (advisor) ; Cajthaml, Tomáš (referee)
This thesis deals with removal of pharmaceuticals and personal care products by constructed wetlands (CWs) and compares its efficiency with removal efficiency of mechanical-biological conventional wastewater treatment plants (WWTP). In the first part the structure of WWTP is described, followed by the structure of CW. Special attention is also paid to the types of CWs, basic principles of function, physical-chemical parameters and vegetation. Below in literature review based on recent works is introduced characterization of selected pharmaceuticals with possible risks. The final section is focused on comparison of case studies from different countries in the world, oriented to the removal of organic polutants, especially PPCPs, from wastewater using various mechanisms including the use of constructed wetlands. Key words: PPCPs, constructed wetland, wastewater treatment plant, wastewater

Carbamazepine - a study on the input to surface waters
Hromádková, Lucie ; Fuksa, Josef (advisor) ; Cajthaml, Tomáš (referee)
Anticonvulsant carbamazepine is a pharmaceutical, which is necessary to be taken continuously. Moreover carbamazepine and its metabolites are resistant to microbial degradation and sorption onto sludge in present municipal wastewater treatment plants. Therefore carbamazepine and its metabolites pass through WWTP and are constantly discharged to surface waters. Concentrations of carbamazepine measured in surface waters are too low to cause acute toxicological effects, but chronic toxicological effects or synergic effects with other pharmaceuticals cannot be excluded. Due to its physico-chemical properties carbamazepine is recalcitrant to degradation in surface waters and in soil, thus it infiltrates through bedrock to ground water. So far there is not enough information on behaviour and effects of metabolites of carbamazepine in surface waters. Besides carbamazepine, also other pharmaceuticals are nowadays often detected in surface and ground water and in the soil. Furthermore, as the population grows the consumption of pharmaceuticals increases as does their input into environment. However, given the risks, which pharmaceuticals in the environment entail, it is necessary to reduce additional input of these micropolutants into environment. As pharmaceuticals can enter the environment by many pathways, there...
