Claim Text:
1. A device for dispersing gas in a liquid comprising a number n of successive zones Z 1 , Z 2 , . . . , Z n comprising static mixing elements having channels, each zone Z i having a length L i , the mixing elements in zone Z i having an effective diameter D i , wherein the individual zones Z i are constructed such that a mechanical energy input E i normalized to the respective ratio L i /D i increases from zone to zone in a direction of flow through the device, wherein n is an integer greater than or equal to 3 and i is an index which runs through integers from 1 to the number of zones n, and the mixing elements present in the zones Z 1 to Z n have a same ratio d i /D i and an effective diameter D i which becomes increasingly smaller from zone to zone in the direction of flow, wherein: d the effective diameter D the effective channel diameter d A a
