What is presented?

Ultrafiltration allows the microbiological assurance of drinking water quality at a lower temperature of the hot water system and therefore an increase in energy efficiency. This technology can be operated permanently in the circulation pipe.

What is special?

Based on the total cell count in flow cytometry and Legionella cultures, key indicators were developed for ultrafiltration devices and the evaluation of drinking water quality. In 13 model buildings, a permanent purification degree of 80 percent was achieved up to the branch pipe of the flats.

What are the potentials?

At reduced hot water temperatures, ultrafiltration permits compliance with the drinking water regulations and safe operation. For a model building, the CO2 emission was reduced by 31 percent. This results in improved drinking water quality and a considerable reduction in costs.
