Wastewater Treatment
Organic Wastewater
Treatment of the wastewater containing organic substances mainly by biological methods to remove BOD, COD, N and P and so on.
Activated Sludge Process with Suspended Carrier
- Low, medium and high concentrated BOD/COD and Nitrogen compounds
- BOD, COD, T-N, NO3-N, NH4-N
Membrane Bioreactor
- Low, medium and high concentrated BOD/COD
- BOD, COD
Denitrification
- Nitrogen compounds
- NO2-N, NO3-N, NH4-N, Organic-N
[Kenko System]Anaerobic/Aerobic Treatment
![[Kenko System]Anaerobic/Aerobic Treatment](img/img102_04.jpg)
- Low, medium and high concentrated BOD/COD, N and P
- BOD, COD, T-N, NO3-N, NH4-N, NO2-N, P
Sequencing Batch Reactor
- Low, medium and high concentrated BOD/COD, N and P
- BOD, COD, T-N, T-P, P

- Medium and high concentrated BOD/COD
- BOD, COD
Activated Sludge Process with Suspended Carrier
- Activated sludge process with used of microorganisms clinging to carriers.
- 1) High-load treatment is performed due to high concentration of sludge being retained.
2) High efficiency and space saving.
3) An existing system can be modified to respond to any increase in load demand. - Low, medium and high concentrated BOD/COD and N
Membrane Bioreactor
- Activated sludge and treated water are separated by use of membrane instead of a sedimentation tank.
- 1) Space can be minimized since there is no need to install a sedimentation tank.
2) Higher concentration of sludge can be retained.
3) High quality of the treated water can be achieved without filtration. - Low, medium, and high concentrated BOD/COD
Denitrification
- Denitrification is obtained by microorganisms which reduce nitrate to nitrogen gas.
- 1) The treatment method is appropriately provided in accordance with the specific requirements.
2) Ammonia can be treated by means of ammonia stripping. - NO2-N, NO3-N, NH4-N, Organic-N
[Kenko System]Anaerobic/Aerobic Treatment
- By combination of anaerobic and aerobic, BOD, N and P are removed.
- 1) Bulking can be prevented, resulting in more stable treatment.
2) BOD reduction is 1.5～2 times more effective than that of a conventional activated sludge method.
3) N and P can be removed at a high rate of 80～90%. - Low, medium, and high concentrated BOD/COD, N and P
Sequencing Batch Reactor
- An activated sludge process operated as a batch reactor by a cycle of aeration, settlement and discharge of the treated water.
- 1) Suitable to treat a small amount of wastewater.
2) Bulking can be prevented, resulting in more stable treatment.
3) Stable performance in removal of N and P. - Low, medium, and high concentrated BOD/COD, N and P
[TROLL]UASB System(BOD High-Load Anaerobic Treatment)
- Converting organic substances in wastewater into methane and CO2 by use of anaerobic microorganisms in granular forms.
- 1) Waste generated is much less since methane fermentation is used.
2) Less operational cost since no power is needed for aeration.
3) The methane gas can be collected, converted, and used as an energy source. - Medium and high concentrated BOD/COD
