In order to develop an efficient and integrated waste treatment and recycling process, as a preliminary step, economically important cyanobacterium, Oscillatoria terebriformis was tested to treat the tannery industry efficient with used in both free and immobilized conditions. Treatment of effluent by Oscillatoria terebriformis for immobilized polyurethane foam cubes was used. The effluent was analyzed initially for physicochemical and heavy metals such as chromium (Cr), Copper (Cu) and Zinc (Zn). Treatment of effluent by Oscillatoria reduced the above heavy metals constituents of the effluent to a considerable amount and brought down the pH to near neutrality. Level of physicochemical and heavy metal was found to be reduced in the effluent treated immobilized cyanobacterium when compared to free and control.
