FujiClean Co.,LTD
About
FujiClean Co., Ltd. is a Japanese manufacturer of onsite wastewater treatment systems, founded in 1961 and recognized as one of the world's leading producers of Johkasou decentralized treatment units. With over two million systems installed in Japan alone and annual sales exceeding 50,000 units, FujiClean holds approximately 40 percent of the domestic Johkasou market. The company's products employ biological activated sludge processes housed in factory-manufactured FRP (fiber-reinforced plastic) tanks produced at proprietary manufacturing facilities. The CE Model provides residential-scale treatment for single-family homes, while the PCN Model incorporates FujiClean's Forward Fluidized Media Chamber technology for enhanced biological contact and nitrogen removal, deployable either as individual units or grouped into small-scale treatment facilities serving multiple dwellings. The ACE1200 serves larger-capacity applications in international markets such as Australia. Cold-climate configurations have been validated through installations in Calgary, Canada. FujiClean has expanded globally with sales bases in Australia, the United States (where a new Georgia manufacturing plant is under development), Germany, the Philippines, Vietnam, Oman, and Canada. The company was recognized as a Global Niche Top 100 Company by Japan's METI in 2020 and its Johkasou technology is registered with the UNIDO Sustainable Technology Promotion Platform.
