The Kujawy Wastewater Treatment Plant was built in 1999 and after twelve years of operation, a modernization of the treatment plant was needed for the removal of nitrogen and phosphorous pollutants, as well as an enlargement by another 100,000 PE (population equivalent).
The project called for a total of 81 pieces of equipment including turbocompressors, agitators, pumps, flow boosters and mixers. The delivery and installation of the equipment was started in the second quarter of the year and concluded in December. The new plant now has a 25% bigger hydraulic capacity and provides 50% better treatment of biogenic components (nitrogen and phosphorus). The energy consumption has been reduced by more than 20% compared to the original plant.
