Membrane Solutions

Kubota's submerged membrane units incorporate microporous membranes (average pore size: 0.2μm) made from chlorinated polyethylene. Capable of delivering high-purity treated water, these compact systems are employed in diverse applications, including wastewater treatment tanks (Johkasou) as well as in the treatment of industrial wastewater and municipal wastewater treatment applications. The membrane separation systems remove not only suspended solids, but also enteropathogenic E. coli, enabling the direct reuse of treated water. Ease of maintenance is another major advantage; treatment facilities can be managed by a small body of staff. In 1998, Kubota advanced into markets outside Japan by delivering a system to a sewage treatment facility in the UK. Kubota went on to promote sales of submerged membrane systems to sewage and industrial wastewater treatment facilities, primarily in Europe and North America; Kubota entered the Chinese market in 2009. A submerged membrane system-based demonstration plant has been set up at the largest treatment facility in China. Kubota will work actively to market the systems in other countries and regions, including Middle East,India and Southeast Asia. Thus far, Kubota has delivered its systems in about 900 projects outside Japan. In fact, Kubota is the world's number 1 in terms of membrane separation systems installed, and world's number 2 in terms of the volume of water treated using its systems.
