* Capital expenditure is comparable with the annual operational cost of conventional bioremediation systems.
* Can be developed and operated in combination with conventional systems to improve the performance of the latter.
* Reduce the ecotoxicity of the man-made substances released into the water bodies and facilitate the eco-assimilation of those pollutants into the ecological cycles thus reducing the quantum of hazardous residues to zero which otherwise require costly secured landfill and incineration techniques.
