  • Pump station arrangement and method for removing harmful fluids from wastewater
    Patent number: 11235995
    Abstract: A pump station arrangement for removing harmful fluids from wastewater and a method for removing harmful fluids from wastewater in such a pump station arrangement. The pump station arrangement includes a pre-chamber, a pump sump, a recirculation channel extending from the pump sump to the pre-chamber, and a gas sensor arranged in the pump sump and configured to measure the content of harmful fluids in the form of gas in the pump sump. The pump station arrangement is configured to recirculate the wastewater via the recirculation channel from the pump sump to the pre-chamber if the measured content of harmful fluids in the form of gas in the pump sump exceed a predetermined value. Also disclosed is.

  • Method and arrangement for an enforced heat transmission between alimentary bodies and gases
    Patent number: 5316076
    Abstract: A method and arrangement for enforced heat transmission between a solid or liquid alimentary body and an ambient gas takes place in connection with cooling/freezing or when cooking, frying or drying the entire part or parts of the alimentary body. This method and arrangement uses a low-frequency standing sound wave. The apparatus uses a low-frequency sound generator having a pulsator part and a resonator part. The resonator part is acoustically virtually closed and is designed so that the alimentary body, which is to be exposed to enforced heat transmission, is located within a zone inside the resonator part where the standing sound wave has a particle velocity anti-node.
