Let's take a look at the principle of the pressurized floating device that lifts and removes dirt!
The pressurized flotation method is a technology that attaches fine bubbles (microbubbles) to coagulated flocs or suspended substances, allowing them to rise rapidly due to the buoyancy of the bubbles. This technology can achieve more than four times the capability of sedimentation methods. Expected effects of pressurized flotation: - Removal of SS (80-95% removal) - Removal of BOD (20-50% removal) - Removal of n-hexane (80-95% removal) - Removal of phosphorus (removal rate varies depending on the amount of PAC or polyaluminum chloride injected) - Removal of COD (over 90% removal for suitable wastewater) - Concentration of activated sludge The key point of the pressurized flotation method is, of course, the generation of fine bubbles, but the ability to properly select chemicals and adjust pH allows for the separation and concentration of various substances. In some cases, it is possible to achieve flotation separation using only fine bubbles without the injection of chemicals. If you can send approximately 20 liters of sample water, we will conduct tests free of charge. Additionally, we can lend out a test machine (1.1kW 200V), so please feel free to contact us through the inquiry page on our website. https://www.edijapan.co.jp/

Company information
Population growth, global warming, and water shortages are threatening the world. To protect our beautiful planet and its limited water resources, we are striving to contribute to environmental measures through energy conservation. Our company introduces and provides products with excellent features not found in Japanese products, assisting you in further promoting energy saving and CO2 reduction. [Announcement of New Products] We have entered into a licensing agreement with the Australian company GOYEN, a specialist manufacturer of dust collection systems, and since July 2020, we have started importing and selling equipment, including pulse jet valves (diaphragm valves) for bag filter dust collectors and maintenance kits for Hosokawa Micron dust collectors, as the exclusive agent in Japan. [Announcement of Company Name Change] Our company (YY Corporation) has changed its name to EDI Japan Co., Ltd. as of January 1, 2015, based on the licensing agreement with Environmental Dynamics International (EDI) in the United States, and has begun operations as the exclusive agent for EDI in Japan. *The business of EDI Japan Co., Ltd. continues to encompass the activities of the former YY Corporation without any changes.
