[EIB (Micro-Nano Bubble) Implementation Results] Chiri Betsu River Bottom Sediment Purification Experiment

To improve the quality of inflowing water! We collected bottom sediment from the Chiribetsu River and conducted tank experiments.

The Chiribetsu River is a second-class river flowing through the Iburi region of Hokkaido and draining into Muroran Port, primarily used for industrial water. It has been confirmed that both the upstream and downstream areas have high levels of coliform bacteria, and improvements in the water quality entering the river have been sought. As a result, purification was carried out using 'EIB (Micro-Nano Bubbles)' to activate indigenous bacteria. As a result, within about a month from the start, the thick black sludge that had accumulated about 10 cm at the bottom was decomposed and transformed into a sandy texture, and after three months, almost all of the bottom sediment had turned into sand. During the process of change, the presence of various protozoan animals in the bottom sediment was confirmed. Tropical fish were raised using the purified water, and they survived without any issues, with a large number of fry hatching and good growth of aquatic plants.
