VOCs at the Gek-Gel/VINAGRO Distillery

The “Gek-Gel” Plant is a modern agro-industrial enterprise with integrated production facilities for wine, spirits, cognac, champagne, and non-alcoholic beverages. In 2016, following a successful collaboration on the construction of a distillery using zero-waste technology, the company approached UTC with the task of recycling excess wine pomace and acidic condensate from the DDGS production facility. Tests revealed a high concentration of suspended solids at 2,000 mg per liter and very high COD and BOD levels. The problem was resolved using a compact combined aerobic-anaerobic treatment solution, which removed 98% of the contaminants. Specifically, the COD values are as follows: inlet—10,000 ppm, outlet—30 ppm.
Configuration of the treatment system: Flotation unit – MBBR – IC – Settling tank. The treatment system has been in operation at the facility since 2017.
