METHOD TO SUPRESS OR REMOVE BLUE-GREEN ALGAE IN THE POND OF LARGE AREA BY MICRO BUBBLES

Serious pollution caused by much propagated blue-green algae kills useful aqueous organisms and causes undesirable and intolerable bad smell and the other effects. Those negative effects further raise the environmental pollution in beautiful and safe nature resulting in inevitable loss of clean environments familiar to us. Until now, small scale evaluation tests for the restoration of clean environment from such kind of serious pollution have been done, however, large scale of the experiment and evaluation tests have not been done with low electric power consumption and without chemical applications. In our present study, we describe the machine (named "Nanomizer") that generate the water flow containing ionized micro-nano bubbles and a successful example that show the restoration of clean water by applying the ionized water to the water polluted by the blooms of blue-green algae, that is, the removal of bad smell and the improvement of water quality by suppressing the growth of blue-green algae in early stage of their blooming in the ash disposal pond of 140 ha and 6 m deep on the site of South Korea - East Power Co. by using two 750 W Nanomizer.
