VEGA Project No. 1/1382/04 Advanced methods for water, wastewater, sludge and organic
wastes treatment (Ján Derco)
Addition of silicate rocks in order to intensify processes of nutrient removal is insufficient and expensive. More
convenient is performance of nitrification and denitrification processes in sludge water in separated reactor with
activated sludge regeneration and phosphorus precipitation in sludge water after sludge stabilisation. Control of
the second step of denitrification process is realistic but too complicated. More appropriate is to optimise
denitrification process by using convenient external organic carbon source for complete denitrification with regard
to actual costs. Anaerobic technology for treatment of corn silage was designed and process parameter values
were determined. Parameter values obtained from laboratory investigation of treatment of organic solid wastes
were used for design, construction and starting-up of full-scale station for biogas production. From results of
testing of anaerobic-aerobic wastewater treatment technologies for small pollution sources followed satisfactory
results in all pollution indicators. Anaerobic baffled reactor is convenient for degradation of
hexamethylenetetramine. Increase of removal efficiency and biodegradability enhancement of biologically
resistant and priority pollutants were achieved by oxidation with ozone and modified procedures of the Fenton
reaction. Significant increase of treatment efficiency of the Fenton reaction was observed after addition of
catechol and hydroquinone.
Project duration: from 01.01.2004 to 31.12.2006
APVV project No. APVT-20-029804: Functional supramolecular surface nanostructure on the
basis of cyclodextrins (Dušan Velič, Josef Prousek)
J. Prousek participation: The study of the radical reactions influence on the stability of cyclodextrin and
cyclodextrin´s complexes. For this purpose the utilization of Fenton reaction has been tested as a source of
reactive hydroxyl radicals.
Project duration: from 01.01.2005 to 31.12.2007
APVV project No. APVV-20-000705 Rapid gas chromatography-mass spectrometry for
analysis of selected organic pollutants in environmental and food matrices (Eva Matisová,
Josef Prousek)
J. Prousek participation: Evaluation of environmental estrogens with endocrine disruptor activity in environmental
and food matrixes. The utilization of different AOP processes for their degradation.
Project duration: from 01.01.2006 to 31.12.2008
VEGA project No. VEGA 1/2462/05 Sensors of chemical toxicity - ascertaining of selected
environmental chemical risk factors by the use of biosensors based on DNA and LDL (Ján
Labuda, Josef Prousek)
J. Prousek participation: The study of different antioxidant and prooxidant activity of some natural phenolic
compounds by the use of Fenton reaction. Further, literature study of environmental pollutants with carcinogenic
activity such are nitroaromatics and polyaromatic hydrocarbons, metals and chlorinated compounds.
Project duration: from 01.01.2005 to 31.12.2007
Bilateral Slovak – Slovene Science and Technology Co-operation Project No. SK-SI-01506:
Development of methodology for evaluation of biodegradability of wastewaters after oxidation
treatment (Ján Derco)
The main goal of the project is to set up appropriate methodology for evaluation of economically and ecologically
applicable treatment methods by means of advanced chemical oxidation processes for heavily polluted industrial
wastewaters as well as landfill leachates with low biotreatability potential. The chemical oxidation processes are
studied as possible independent or pretreatment methods before biological treatment. The study will be
conducted also with synthetic and actual wastewaters. Biotreatability of the wastewaters will be evaluated prior
and after optimised chemical pretreatment using complex toxicity and biodegradability assessment. Those
characteristics are considered as key summary factors for effective performance of biological wastewater
treatment plant. It is expected that combination of both treatment methods will lead not only to pollution prevention
but also to the overall cost management of related wastewater treatment plants. Methodology will gain knowledge
on wastewater treatment and it will improve understanding of behaviour of the heavily polluted persistent
wastewaters.
