VCs invest $4.4m in Japanese filter technology start-up

The company was set up in 2002 and claims to have developed a so-called ultrasonic atomization separator system derived from alcohol enrichment technology used in the sake brewing industry.

According to a release, the technology replaces existing methods - such as distillation, reverse osmosis, and centrifugation - for separating and recovering particles from liquid compounds. The advantage of the technology is that it eliminates the use of heat and pressure, thereby offering lower energy costs.

Applications for the technology include industrial-effluent treatment, food processing, and seawater desalination. Last year, the company launched a joint research venture with Tsuneishi Shipbuilding to develop new systems for treating exhaust gas from ships in response to global regulation.

With this investment INCJ will support the commercialization of the technology, while Tsuneishi Partners will look to further support R&D and manufacturing through Tsuneishi Group's subsidiaries.
