<p>The invention concerns a method and device for introducing a gas or gas mixture into a liquid using a filter through which the gas or gas mixture is introduced into the liquid. According to the invention, in order to provide advantageous introduction conditions, the liquid is guided in a surface-parallel flow at a minimum flow speed of 0.5 m/s via a multifilament filter mesh (5) which is supported on a support surface on the side remote from the liquid flow. The gas or gas mixture is fed in a manner restricted locally by the support surface to the filter mesh (5) which lies loosely against the support surface at least in given regions, along the liquid flow path.</p> |
