Reliance on coal as an energy source has led to significant by product management relegated to the storage or disposal of fly ash generated as a result of combustion. Disposal of the ash is a major source of environmental pollution in the areas surrounding the production and disposal site. Therefore an inexpensive by product management technology is needed for the environmentally safe disposal or storage of this material until beneficial uses for this by product are developed. Fly ash has shown quite effective absorbent capacity for COD reduction from the domestic waste water though its capacity lower than that of the activated carbon, The low material cost makes it an attractive option for the treatment of domestic waste water. Hence in the present study was undertaken to identify fly ash as an alternative treatment source. The efficacy of continuous reactor for COD reduction using fly ash with the help of hydraulic free jet was studied .for this purpose a system of standardized continuous reactor under steady state conditions is used to study the effect of this media .for a fixed residence time ,absorbent dose ,pH of the media, and initial COD concentration ,percentage reduction in COD was evaluated. It was found that about 84 percentage reduction in COD Could be achieved under controlled conditions.
