Biological decomposition of organic material
Abstract
Abstract AN AQUEOUS LIQUID WITH AT LEAST 1% BY WEIGHT OF ORGANIC MATERIAL IS MAINTAINED IN ROTATION IN A TREATMENT VESSEL IN THE PRESENCE OF THERMOPHILIC MICROORGANISMS INCLUDING THERMOPHILIC BACTERIA, THERE BEING AN ELAPSED TIME OF 2 TO 200 SECONDS FOR EACH REVOLUTION OF THE TOTAL VESSEL CONTENT. AIR IN THE FORM OF FINE BUBBLES IS SUPPLIED TO THE ROTATING LIQUID IN A QUANTITY RATIO OF ONE PART BY VOLUME OF AIR TO 5 TO 100 PARTS BY VOLUME OF LIQUID DURING EACH REVOLUTION THEREOF, THE LIQUID BEING HEATED WITHOUT HEAT ADDITION AND BY THE ACTIVITY OF THE THERMOPHILIC MICROORGANISMS TO A TEMPERATURE OF AT LEAST 42* C. WHERE THE MICROORGANISMS ARE ACTIVE. THE REVOLVING LIQUID IS KEPT HEAT-INSULATED, PREFERABLY BY FOAM FORMED IN THE BIOLOGICAL DECOMPOSITION; AND PREFERABLY BOTH THE LIQUID AND THE FOAM ARE MAINTAINED IN ROTATION IN A VERTICAL PLANE AND IN A DIRECTION SUCH THAT THEY MOVE OUTWARD FROM THE CENTER OF THE VESSEL AT THE REGION OF THEIR INTER-CONTACTING SURFACES.
