Features

  • Excellent Permeate Quality

    MBR treatment removes suspended solids (SS) via the physical barrier of a membrane filter, making MBR effluent extremely clear. Similarly E. Coli is completely removed, as it is larger than the membrane’s pore size, so MBR effluent is safe and clean for many recycle uses. The longer Sludge Retention Time (SRT) of MBR systems can improve removal of organic material and total nitrogen (TN) removal and result in a more stable operation. As a result, effluent is cleaner and odorless. This makes MBR effluent good for both the environment and humans, and enables its reuse for groundwater recharge, irrigation, washing, and many other applications.

  • Remarkably Small Footprint

    The Kubota MBR system requires less aerated volume than a CAS system. This is accomplished by increasing solids loading and MLSS concentration up to three times higher than a CAS system can handle. This is made possible by the large hydraulic capacity of the Kubota MBR System. Kubota’s MBR systems also do not require a primary or secondary clarifier, since the membranes physically separate the water from the solids. Furthermore, excess sludge can be wasted from the membrane tank where it is already partially thickened, reducing the amount of sludge thickening required. As a result, the footprint of the MBR system is considerably smaller than that of a CAS system. Due to these advantages, retrofitting an existing plant with a Kubota MBR System can lead to increased treatment capacity without requiring any new tanks.

  • Simple Maintenance

    The Kubota MBR system does not need a secondary clarifier, so microbe observation and adjustment of the Return of Activated Sludge (RAS) is not unnecessary. This reduces operator training needs and simplifies maintenance overall.
