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. [Verification Experiment] ■ Title: Chiribetsu River Bottom Sediment Purification Experiment ■ Period: February 20, 2015 – March 20, 2015 ■ Location: Bottom sediment from the Chiribetsu River was collected, and tank experiments were conducted at our company ■ Information: It was confirmed that both the upstream and downstream areas had high levels of coliform bacteria ■ Purification Method: Purification through activation of indigenous bacteria using EIB *For more details, please refer to the PDF document or feel free to contact us.

Lake Biwa, located in Shiga Prefecture, is the largest lake in Japan in terms of area and water storage capacity. However, organic matter such as algae and bacteria settles at the bottom of the lake, leading to the formation of sludge, with approximately 2 millimeters accumulating annually in the southern lake. To address this, purification was implemented through the activation of indigenous microorganisms using 'EIB (Micro-Nano Bubbles).' As a result, the thickness of the sludge at the bottom of the closed water tank decreased by 8 cm over 130 days, and it was found that simply circulating lake water containing ultra-fine bubbles could activate microorganisms present in nature and decompose and eliminate the sludge. 【Verification Experiment】 ■ Title: Lake Biwa Purification Experiment ■ Duration: March 2013 – 160 days of operation ■ Location: Yanagisaki, Lake Biwa (Otsu City, Shiga Prefecture) ■ Information: Organic matter such as algae and bacteria settles at the bottom of the lake, leading to sludge formation. ■ Purification Method: Purification through the activation of indigenous microorganisms using EIB. *For more details, please refer to the PDF document or feel free to contact us.

Hyouko is an artificial lake located in the Suibara area of Agano City, Niigata Prefecture, where problems arose due to the accumulation of sludge caused by the feed and droppings of gathered wild birds, as well as decaying plants. In response, purification was carried out through the activation of indigenous microorganisms using 'EIB (Micro-Nano Bubbles).' As a result, although it was a short-term test, signs of improvement were clearly observed in the bottom sediment around the device, and no negative impacts on the surrounding area of the device were confirmed. It is believed that the plankton that decomposes the bottom sediment was activated by this device, and it was confirmed that the lake was improving in water quality more than expected. 【Verification Experiment】 ■ Title: Hyouko Purification Experiment ■ Duration: September 14, 2011 - September 30, 2011 ■ Location: Hyouko (Agano City, Niigata Prefecture) ■ Information: Sludge was generated due to the feed and droppings of gathered wild birds and decaying plants. ■ Purification Method: Purification through the activation of indigenous microorganisms using EIB. *For more details, please refer to the PDF document or feel free to contact us.
