MBR and Traditional Activated Sludge Process Comparison

Advantages of MBR
1.

High effluent quality
• Permeate – free of suspended solids

2.

Small footprint, elimination of secondary clarification tank
Only half of the area of conventional activated sludge process is required, and capital cost is reduced
Solve the problem of poor sedimentation in conventional activated sludge process; especially for winter

3.

Long solid retention time, easy management
Sludge wasting volume is greatly reduced

4.

High biomass concentration and treatment efficiency
Operate at biomass concentration of 10,000 – 20,000 mg/L, COD removal and denitrification occur simultaneously

5.

Easy to install in the existing aeration tank to become a MBR system

6.

Easy for operation & maintenance

7.

Greatly reduce the volume of aeration tank

8. Reduce fouling and increase water flux
