Toyoda Gosei develops DUV LED water purification module
Toyoda Gosei Co Ltd of Kiyosu, Aichi Prefecture, Japan has developed deep-ultraviolet (DUV) LED light modules for use in eliminating viruses and bacteria (replacing mercury lamps, for which there are environmental concerns).
As the first mass-produced application, deep UV LED water purification units are being used on water recirculating WOSH portable washstands, which will be sold by WOTA Corp from November.
Founded in 2014 as a startup from Tokyo University, WOTA aims to create decentralized, autonomous water recirculation systems in society. Its business centers on R&D and the supply of next-generation independent water infrastructure.
WOSH portable washstands purify and reuse water many times, and so can be used outdoors, at store entrances and other places where the water supply is limited. In addition to regular filter and chlorine purification, the washstands use deep UV irradiation to achieve a higher level of purification.
The partnership between Toyoda Gosei and WOTA has been deepened in September by Toyoda Gosei’s purchase of convertible bonds from WOTA, the most recent of its corporate venture capital investments.
