Abstract
A biochemical-action vessel accommodates a substrate in which biochemical reactions are caused by microorganisms. A heat-exchange arrangement is provided in the vessel and removes the heat generated in the substrate by such reactions. The substrate is circulated in the vessel advanced by an advancing arrangement in a closed path which passes through the heat-exchange arrangement. Aerating gaseous medium is introduced into the substrate upstream of the advancing arrangement and in the region of suction generated by the same, and entrained by the circulating substrate so as to supply the oxygen necessary for the aerobic growth of the microorganisms.
