Water treatment for 48 MW cooling capacity

E.ON SE, a CHP plant in Heidelberg, Germany, providing heat, cooling, and steam to the "Im Neuenheimer Feld" area, is expanding its cooling capacity in response to the increasing demand at Heidelberg University Hospital campus.

The new cooling center is designed for a maximum capacity of 48 MW and a volume of up to 12,000 m³ of cooling water. Silhorko-Eurowater is responsible for the design and manufacturing of the complete water treatment solution for the first expansion stage of the cooling center. A total of 4 expansion stages are planned. The water treatment system consists of reverse osmosis with antiscalant dosing to prevent membrane fouling. Demineralized water is employed for the operation of the cooling towers and helps improve their performance and energy efficiency. 

In the initial expansion stage, the new cooling center will provide an output of 12 MW. Together with the already operational cooling center with a generation capacity of 40 MW, this establishes one of the largest cooling supply complexes in both Germany and Europe.
