ABSTRACT:
A method and a device for removing suspended particles from a liquid by means of gas-bubble flotation, in which, before the gas-bubble flotation step proper, the liquid is more or less saturated with the gas in one or more preceding gas introduction steps, so as to obtain a longer average life-time of the smaller gas bubbles in the final flotation step.
