The validation testing of advanced oxidation processes for the removal of pharmaceuticals from the effluent WWTP

 

  • Fate and effects of micropollutants in the aquatic environment/University of South Bohemia in Ceske Budejovice – Tomáš Randák

 

  • Pharmaceuticals in drinking water at the Káraný water treatment plant/E.G.Masaryk Water Research Institute – Zbyněk Hrkal

 

  • Pharmaceuticals in surface water of Vltava river catchment/Povodí Vltavy state enterprise – Marek Liška

 

  • Innovative carbon-based sorbents as an efficient way of wastewater treatment/Technical University of Ostrava – Roupcová Petra 

Micropollutants and their metabolites enter the aquatic environment from a variety of sources with the main sources of contamination being sewage, agricultural effluents and even recycled municipal wastewater for parks and gardens. The project will prepare and analyze carbonaceous sorbents based on biochar and other selected carbon compounds. Furthermore, a treatment unit will be designed for final purification and disinfection of wastewater from selected micropollutants. This pilot unit will subsequently be installed as a pilot plant at the Příbram WWTP which is connected to 2 medical facilities and at the Ostrava WWTP.

CarbonCLEAN® Project of a demonstration pilot plant for the removal of pharmaceuticals from wastewater
  • Norway: Monitoring of microplastics and use of digital tools on removal of marine litter/’Centre against Marine Litter – Nowegian Environment Agency – Ragnhild Nylund

 

  • Monitoring of pesticides in the environment and methods of their elimination/Technical University of Ostrava – Tereza Motúzová 

 

  • CarbonCLEAN: Removal of pharmaceuticals from waste water using textile filters containing biochar/AIVOTEC Ltd. – Sylvie Kříženecká 

The aim of the project is to demonstrate the effectiveness of the removal of selected drugs on real wastewater and in real technological conditions of the WWTP in a demonstrative pilot plant and to determine the possible need for partial technological modifications of the filtration equipment so that it can be used in normal operation. Technically, replaceable textile filters with CarbonCLEAN® sorbent, which is a biochar-based materiál, originally developed by the AIVOTEC, will be used.

  • The validation testing of advanced oxidation processes for the removal of pharmaceuticals from the effluent WWTP/Brno University of Technology – Tomáš Macsek

Our goal is to test in operation methods for reducing water pollution in the form of drug residues. In the project, we will use oxidation processes based on ozonation and technologies close to nature, such as artificial wetlands or biofilters, to purify water. The project will be implemented at two selected locations – the wastewater treatment plant in Blansko and the Research Institute of Veterinary Medicine in Brno. The aim of the project is to reduce this pollution by at least eighty percent.

  • Decentralized removal of micropollutants from infectious hospital wastewater/Prague Water Supply and Sewerage, Inc. – Robert Kvaček

The project is focused on reconstruction of existing WWTP and installation of advanced treatment technologies. Wastewater Treatment Plant (WWTP) is located in Prague 4 – Krč on the premises owned by the Partner. The existing WWTP does not meet the conditions required by ČSN 75 6406 and its outdated biological line and chloration do not provide complete disinfection and removal of pharmaceuticals before discharge into sewage network. As of now, wastewater treated in existing hospital WWTP is discharged into sewage network and treated in a large-scale municipal WWTP. From environmental point of view it would be more suitable to provide completely decentralized treatment on-site followed by discharge into Kunratický stream. This solution would also help mitigate the on-going problems with insufficient flow in the stream. The proposed solution is an upgrade of the existing WWTP by providing a microfiltration separation unit, ozonation unit and GAU sorption unit. During wet weather flow, wastewater and stormwater exceeding the hydraulic capacity of the WWTP will be disinfected and discharged into municipal sewage network. The project will provide the medical facility with a powerful tool for removal of pharmaceuticals and their metabolites, thereby significantly decreasing the specific pollution of the sewer network and reducing the risk of antibiotic resistance in bacteria. The proposed technology will also be able to disinfect infectious waters. Treated effluent which will be discharged into municipal sewage network or recipient water body can provide a constant supply of water for the aquatic fauna and flora. This will be a significant contribution especially in the summer months when the flow fluctuates significantly.

  • Utilization of advanced oxidation processes for effective removal of gabapentin and ibuprofen from wastewater/Agrovýzkum Rapotín s.r.o. – Martin Vašinka

The aim of our project is to install the pilot unit of the tertiary degree of wastewater treatment in WWTP Moravský Beroun. The realization of the project is located on the territory of the protective waterband in which springs of mineral water, which are collected for commercial purposes. For this reason, it is necessary to limit the entry of foreign substances and their metabolites into surface and subsequently into groundwater. As part of the project, we will install a new three-stage system that will allow us to reduce water pollution with drug residues. If this system proves successful in practice, it will be implemented for the entire capacity of the treatment plant.

  • Reduction of surface water pharmaceutical substances pollution in biologically treated wastewater/Technical Univerzity of Liberec – Tomáš Lederer

The project is focused on the elimination of anthropogenic pollution by pharmaceutical substances (especially resistant antibiotics) from wastewater, which leads to the accumulation of unnaturally occurring substances in the environment. At present, wastewater treatment plants do not have technologies that would be able to eliminate these pollutants from wastewater, and are therefore further entrained in the environment (especially in surface water). It is therefore in the general interest to reduce the input of this pollution, thereby protecting itself and the environment. Due to the evident dominance of the input of pharmaceutical substances into the environment from surface sources (wastewater from the population) (Santos et al., 2013), the project intends to eliminate or reduce the input of these substances from the effluents of biological wastewater treatment plants. The project partners will realize field-tests of technologies that have been developed at both sites and promise very effective removal of the contaminants in question from the wastewater.
