The KUBOTA Submerged Membrane Unit® incorporates microporous membranes made from polyolefin. Although fluids which are smaller than the membrane’s micropores can permeate the membrane, contaminated ingredients cannot permeate it due to their larger sizes. Water flow created by aeration, and air bubbles contact the membrane’s surface and move upward while vibrating the surface. This keeps the membrane surface always clean and prevents the micropores from clogging.
Flagship projects include Palm Island Dubai and the southern hemispheres largest urban reuse STP in NSW Australia. The Kubota membrane STP has been meticulously designed and manufactured and is in use in large thousands of large scale government plants worldwide. As membrane manufacturers, Kubota were at forefront of membrane development and continue to be industry leaders due to their ongoing commitment to R&D. Kubota membrane units treat approximately 80,000,000ML of sewage per day globally.
A key advantage of the Kubota membrane system is the quality of treated water produced, which allows reuse to any application, including waterway discharge and inhouse reuse.
Kubota Membrane STP’s provide peak flow management and incorporates buffer storage and emergency storage into the treatment chain. The plants control varying flow volumes and concentration at all times, maintaining a high level of treatment and providing operational security.
