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.
