Original Abstract

The winery wastewater (WWW) is produced mostly by equipment cleaning, during which compounds like ethanol, organic acids (mostly acetic acid), unfermented sugars, polyphenols etc. contaminate the WWW. Especially during vintage season (grape crushing), the WWW shows a high chemical oxygen consumption (COD) and low pH, which are extremely far from discharge limits to surface water, and typically not acceptable even for wastewater treatment plants. A combination of evaporation and stripping showed promising results for COD reduction of WWW. The wastewater composition is crucial to assess the recycling technology’s feasibility and aid the design procedure. The analyzed parameters were COD, pH, amount of fructose, glucose, ethanol and acetic acid. WWW samples for this research were taken at a winery in South Moravian region at the beginning of October 2022 (the critical period of the vintage season) and analyzed at biweekly (14 days) intervals for 1 month. Parameters were determined by different methods: COD photometrically using COD cell test, amount of fructose and glucose by HPLC, ethanol by GS–FID and acetic acid by IC. The results show that the winery wastewater storage time can have a decisive effect on the performance of the technology based on evaporation and stripping. At the same time, it is possible to optimize the storage time to achieve a certain technological goal.
