The challenge
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).
After a thorough quality and efficiency analysis, Sulzer was selected to make the final proposal for the plant modernization.
The solution
During 2011-2013, we finalized the design and in December 2013 we signed the significant contract for the delivery of altogether 81 pieces of equipment including turbocompressors, agitators, pumps, flowboosters and mixers.
The delivery and installation of the equipment was started in the second quarter of 2014 and the last submersible XFP pump was delivered to the Krakow wastewater treatment plant in December.
The XRCP 800 is specifically designed for pumping and recirculation of activated sludge in the denitrification/nitrification process of a wastewater treatment plant. This compact and easy-to-handle pump is efficient and reliable.
This was our biggest project in Poland so far and a great challenge for our people. It was rewarding to see how the customer gained even more confidence in the delivered products day by day. Marcin Jankowski, Sales & Project Manager, Sulzer Pumps Wastewater Poland
Customer benefits
Sulzer offers a wide range of aeration systems for municipal and industrial wastewater treatment. Our application and process know-how combined with our unique product portfolio provide customers with high-tech solutions that guarantee efficiency and process reliability at minimal life cycle-cost.
