The Kubota Connection


In 1989 the Kubota Corporation started to develop a reliable membrane technology to treat wastewater. Following a substantial research and development effort, Kubota developed a flat-plate membrane technology that was accepted by Japanese Government and has since revolutionized wastewater treatment in Japan.


Today, there are over 1,400 MBRs in Japan and on the order of 1,600 facilities worldwide. In fact, Japanese wastewater treatment regulations (Johkaso) now require Kubota MBR membranes be used in certain applications.


Kubota has provided quality heavy equipment to the US market for over fifty years and is continuing that tradition with our Submerged Membrane Unit (SMU). The Kubota Membrane USA (KMU) Corporation is focused on providing the most reliable MBR membrane technology available as part of EQMBR Systems.


In early 2001, Kubota formed a partnership with Enviroquip to service the US market based on their history of providing complete wastewater treatment plants since 1966. Enviroquip, like Kubota, understands that any WWTP is only as reliable as it’s weakest component. Moreover, Enviroquip recognizes that the key to optimizing the hydraulic performance of any submerged membrane technology is biological process control.

As an integral part of the EQMBR, the Kubota SMU will be manufactured in the US to expedite deliveries and ensure prompt after sale support. In addition, our technical staff brings the global experience of our international partners to bear on every project at the request of Enviroquip. With over 1,000,000 cartridges in circulation worldwide and a production capacity on the order of 7MGD/month, KMU provides Enviroquip with cartridges that are backwards compatible with units manufactured over 14 years ago.
