A known method for removing biomass from a liquid eliminates only cells bonded on solid substances and proteins, but not suspended cells. The present invention relates to a method enabling a larger amount of biomass to be removed with a lower consumption of chemical products, energy and water, whereby liquid first runnings, the biomass contents which is lower than that of the operating liquid, are fed into the reactor; a Redox potential not falling below a set first-runnings value is placed in the operating liquid at least in a locally delimited area; the operating liquid is fed into the reactor after the Redox potential has been placed into the first-running liquid, while a Redox potential not falling below a set first operation value has been placed in said liquid at least in a delimited area, which operation value is to be sufficiently high to damage the cells contained in the operating liquid to such an extent that they cannot float anymore; and the operating liquid is cleaned by flotation. |
