Aerobic Submerged Attached GrowthBioreactor: A SuitableDevice for IntermediaryWastewater Treatment
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.

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.
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 .
