The thickness of the sludge at the bottom of the closed water tank decreased by 8 cm in 130 days! We will introduce a case of implementing EIB in Lake Biwa.
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.
