  1. 1. The removal of SelectedPharmaceuticals on WWTPin the Czech RepublicF. Wanner, M. Váňa, L. Matoušová, J. K. Fuksa, D. Pospíchalová 1st Bulgarian National YWP Conference, 17.5. 2012, Sofia
  2. 2. IntroductionRemoval of organic pollution on WWTPs has been practically solved.Improving removal efficiency of Nitrogen and Phosphorus on WWTP. Attention of public now focusing on new specific pollutants. PPCP (pharmaceuticals and personal care products) The consumption of these substances is rising. Wastewaters→ WWTPs→ Receiving waters Removing?
  3. 3. Research project in the Czech Republic The possibilities of removing selected specific pollutants (PPCP) on WWTP The goals of the project is to describe: Concentrations of selected PPCP in the wastewaters Treatment efficiency of classical biological WWTP Propose and verify optimal technologies for PPCP removing The main work packages of the project: 1. Literature research of up-to-date knowledge about removing selected PPCP on WWTP. 2. Monitoring of PPCP concentrations in the influent and effluent on selected WWTP in the Czech republic. 3. Model of WWTP for verifying advanced technologies for better PPCP remove.
  4. 4. Observed substances • Analgesic and Non-steroidal anti-inflammatory drug (NSAID). About 70% used as liniment Diclofenac (over-the-counter), except Europe used per(CAS 15307-86-5) orally. • Consumption in the CR c. 20 tons per year. • Non-steroidal anti-inflammatory drug (NSAID). Ibuprofen Generally used per orally.(CAS 15687-27-1) • Consumption in the CR c. 200 tons per year. • Anti-epileptic, antidepressant etc. Used purelyCarbamazepine per orally and only for prescription.(CAS 298-46-4) • Consumption in the CR c. 7,5 tons per year.
  5. 5. Observed substances • Basic metabolite of Acetylsalicylic AcidSalicylic Acid (Aspirin). Direct usage only for eyes(CAS 69-72-7) applications. • Consumption in the CR c. 600 tons per year. • Basic metabolite of fibrates used for levelClofibric Acid control of lipoproteins (cholesterol) in blood.(CAS 882-09-7) • Consumption in the CR c. 10 tons per year.

  20. 20. Discussion of the resultsIbuprofen, Salicylic Acid• Biologically degradable• Total treatment efficiency up to 99%.• Significant Concentrations on the Effluent.Diclofenac, Carbamazepine• Resistant toward biological treatment process.• Low treatment efficiency (max. 33 % for DIC and max. 27 % for CAR).• Often noticed increase of the concentrations after passing WWTP.Clofibric Acid• For evaluation more detailed data missing.
  21. 21. ConclusionsVarious Treatment Efficiency for selected PPCPThe main factors of high removal efficiency of IBU and SAL: Hydraulic retention time Sludge ageSpecific setting of technological line and usage of wastewatertreatment technology is not so important as supposed.Mechanical pretreatment is not important for removingpharmaceuticals at all.Tertiary Treatment must be added for higher removal.
  22. 22. The next phase of the projectAssembled WWTP pilot plant with real wastewater.Testing of various settings of WWTP line and maintechnological parameters.Adding tertiary treatment: 1. Ozonization 2. UV radiation 3. PAC (Powdered Activated carbon)
