4 Foot print Moderate Low Low ( depends on media fill factor in MBBR tank, type of liquid solid separation unit e.g. settling tank verses DAF unit etc ) Low Low
5 Fat , Oil and Grease Tolerance High Low High ( MBBR system may tolerate higher FOG concentration when it is compared to MBR system ) Low High
6 Control Simple Complicated Simple Simple Simple
7 Effluent Reliability / Quality Consistency High Low High Low High
8 Cost on sludge trea Cost on sludge treatment (digestion , thickening / dewatering) : Moderate Cost on sludge treatment (digestion , thickening / dewatering) : Low Cost on sludge treatment / disposal (digestion , thickening / dewatering , tankering etc ) : Moderate Cost on sludge treatment (digestion , thickening / dewatering) : Low NA - No Sludge Production
