Excellent Permeate Quality:

MBR treatment remove 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 & 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 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 possi ble by the large hydraulic capacity of the MBR system. MBR system also do not require a primary or second ary clarifier, since the membranes physically separate the water 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 this advantage, retrofitting an existing plant with a MBR system can lead to increased treatment capacity without requiring any new tanks.

Simple Maintenance:

The 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.
