Abstract

Oxygen-deficient water in the enclosed coastal seas becomes more serious recently. Micro-bubble technology has been paid attention as a method to relieve oxygen-deficient water by aerating directly just above the sea bottom. Field studies on development on the micro-bubble systems have been done at some areas in Tokyo Bay since 2003. This paper presents the problems in these development processes and the solutions. The problems are the rise power of the big air bubble included in the micro-bubble, protection of equipment by pressure build-up and an energy supply way to equipment. To solve it, the method of measures was examined about these problems. 1) Development of a big air bubble remover. 2) Equipment protection system development by pressure measure. 3) Self-sufficient energy use which doesn't require an electric transmission cable.
