■ Comparison between MBR process to conventional wastewater treatment
Item | Conventional Wastewater Treatment | MBR |
---|---|---|
Process Componets |
Pre-treatment Biochemical reaction tank Coagulation tank Sedimentation ank filtration Sterilization Interim tank. |
Pre-treatment MBR tank Sterilization Interim tank. |
Construction Requirements |
Not easy to achieve modular design. It is better to build all system in one time |
Modular design. It is suit for stage construction, save cost. |
Site Requirements |
Restrain to site | No restrain to site. Can make ground type, semi-ground type and under ground type. |
EffluentQuality | Reach the first level A criteria of the national discharge standard | Better quality than the first level A criteria of the national discharge standard |
Occupation Area |
Large | Small |
Water Productivity |
Sand filter tank or actived carbon tank need to backwash frequently. Process itself will consume water, so producing water rate is low |
Backwashing is not required. Producing water rate is high. |
Excess Activated Sludge |
Suldge production is high, the cost of sludge disposal is high too |
Sludge production decrease , the cost of sludge disposal is reduced too |
Chemical Sludge |
Need to add many chemical reagent produce chemical sludge. Easy to make secondary pollution |
No need to add chemical reagent no chemical sludge. |
Operation Management |
It is easy to have breakdowns because of complex mechanical structure. Need professional person to maintain the system. |
Simple mechanical structure and operating process. Full process can be auto-control. Operator only need a simple training. |
Effluent Application |
Limited application: water for toilet flushing ,roadsprinkler and City green. |
The effluent quality is good which can be widely used in toilet flushing water, roadspinkler water, city greening water, automobile washing, Construction site water and scenic environment water and so on. |
