The membrane bioreactor systems combine proven ultrafiltration technology with biological treatment for municipal, commercial and industrial wastewater treatment and water reuse applications. The membrane bioreactor system incorporates reinforced hollow fiber membranes specifically designed to meet the requirements of wastewater treatment. Membrane bioreactor systems replace conventional treatment and combine clarification, aeration and filtration into a simple and cost-effective process that reduces capital and operating costs. The result is consistent, high quality effluent suitable for any discharge or reuse application.

Compared with conventional activated sludge system, the membrane bioreactor system is much simpler, as shown below.

MBR system's advantages include the following:

• almost complete solids and bacteria (Giardia and Crypto) removal;
• high effluent quality; modular design with good expandability;
• robustness in recovery resistant to upsets due to shock loadings or peak and fluctuating flows;
• sludge age or SRT (solids retention time) and hydraulic residence time (HRT) are controlled separately;
• less odor;
• sophisticated but yet simple controls.
