Thanks to all these new developments it was possible to increase the heat extraction rate by up to 40%. That means, without the anti-fouling system and without the new ferritic steel, the heat exchanger chains would have to be 40% longer. Together with a bivalent process control system, sewage heat recovery plants now score with a ROI of 2 - 6 years.
