Bioreactor Design
1. Am I Surface Water Scientist ?
Specific to Hydrology, water shed,
pollution but not limnology
Skill towards Environmental
Innovations & contribution to this
emerging science
Water quality to aquatic life,
agricultural use and recreation &
aesthetic purpose
2. Aerobic Submerged
Attached Growth
Bioreactor: A Suitable
Device for Intermediary
Wastewater Treatment
3. Specific Objectives:
To assess the organic matter degradation
efficiency under different solids and
salinity proportions in wastewater.
To evaluate ammonia nitrogen removal
capability under submerged condition of
bioreactor.
To find out relation between bacterial
intensity and the degree of waste removal.
7. Measuring parameters and instruments
Measured parameters Measuring instruments

25. Conclusion
Aerobic submerged bioreactor has
been proved to be a potential device
for secondary treatment of
wastewater.
The rate of remediation of
wastewater depends on the intensity
of bacterial growth.
High salinity retards the remediation
process i.e. the bacterial growth.
26. Conclusion
The experimental results indicate
that spherical shaped. i.e. the small
size tire chips are better for bio-
remediation for landfill leachate
treatment than rectangular shape.
In submergence bioreactor clogging
rate is slower than trickling filter
and clogging can be eliminated
through backwashing .
