Ground Level
|
Transfer Efficiency
|
Low
( As air mixing with wastewater from the bottom of the aeration tank )
|
Very High
( As Air mixing with wastewater from above ground level of the aeration tank, water Dissolved Oxygen saturated before distribute an excess air to the bottom of the aeration tank )
|
Mixing Ability
|
Fair
|
Very High
|
Air Suction Capability
|
Difficult
( As the designed principle works against atmospheric pressure )
|
Easy
( As above ground level mixing condition )
|

Fair
|
Low
|
Total Weight
|
Very heavy
( As the designed principle use self-weight for stability installation )
|
Light
( As the designed principle does not require heavyweight )
|
Maintenance
|
Very Difficult
- Very Heavy
- Easy wear on submersible turbine
- Frequently Inspection require
- Hardly to maintenance
- Costly spare parts
- Costly maintenance
- Poor support due to change of local agent
|
Very Easy
- None clogging
- No moving part
- Fixed and forget
- No spare part requires
- Low maintenance
- Local manufacturer support due made in
|
Life Span
|
Short
( As a lot of moving parts via the designed principle and installation concept )
|
Long
( No moving part, None Clogging )
|
Power Consumption
|
High
|
50% Lower !!!
