PURIFICATION SYSTEM OF OCEAN SLUDGE BY ACTIVATING MICROORGANISMS

Abstract

Ocean sludge exerts a very big environmental load to local sea area. Here, attention was paid
to micro-bubble technology for application to the purification of sludge. The important point in this technique
is to activate the bacteria existing in the area by micro-bubbles. We had developed a method for decomposing
the sludge by using of microorganisms in an aerobic state by micro-bubble. In this study, our objects are to
develop a new powerful purification system for sedimentary sludge using a micro-bubble device and by
activating microorganism. As the results of our experiments, we succeeded in reducing the time needed to
purify the sludge.
