STOCK Lublin, Poland
The new Wastewater Treatment Plant (WWTP), located at the STOCK Lublin company, was designed for the pre-treatment of wastewater from alcohol production. The treatment process includes mechanical and anaerobic pre-treatment stages, followed by chemostat before the effluent is discharged into the sewer. The anaerobic pre-treatment was implemented to reduce organic pollutants and other parameters in accordance with the maximum permitted discharge limits into the sewer.
