Abstract

The present invention relates to a procedure and a means for processing liquids, such as for oxidizing, flotating or treating in other desired ways. In the method a liquid to be processed is conducted as an in-flow (A) into a first volume (12). Dispersion liquid and the air/gas/liquid dissolved therein is conducted into said first volume (12) or into a volume in the immediate adjacency therebelow for intermixing the liquid to be processed and the dispersion liquid containing air/gas/liquid. The mixed, processed liquid mixture containing bubbles is made into an upward motion, whereby impurities are accumulated into a suspension surface (28). At least part of the liquid to be processed is conducted as a suction flow (K') into a pump (17). Air/gas/liquid is drawn with the pump (17) as a flow (B) into the suction flow (K'), whereby the air/gas/liquid at a pressure generated by the pump (17) is dissolved in the pump (17) and in the discharge side thereof into the circulation flow (K), reacting possibly with reactable components in the circulation flow (K). At least part of the processed circulation flow (K) is returned with the pump (17) into the liquid to be processed.
