Abstract: A microflotation system for treating a body of water includes a pressure apparatus configured to produce pressurized water, an expansion valve positioned at a predefined water depth in the body of water and a pressurized water line configured to connect the pressure apparatus to the expansion valve. The system further includes a floating body and a supporting structure connected to the floating body and is structured to maintain the expansion valve at the predefined water depth. A base wall is coupled to the supporting structure and positioned below a surface of the body of water. A circumferential side wall is connected to the base wall and a microbubble stabilization zone is positioned downstream of the expansion valve and is at least partially delimited from the body of water by the base wall and the circumferential side wall.

Abstract: A microflotation system comprises a flotation tank with a dispersion water feed line in which an expansion valve arrangement is disposed. An adjusting apparatus is configured to adjust a flow rate of the expansion valve arrangement and an electronic control is connected to the adjusting apparatus. A measuring apparatus is disposed downstream from the expansion valve arrangement for detecting a size distribution of gas bubbles and the electronic control is configured to set the flow rate depending on a size distribution detected with the measuring apparatus.
