Water being one of the most precious resources for the Survival of life is on the verge of depletion and hence various treatment processes to treat wastewater are being researched. Speaking about waste, another solid waste comes into the picture which is available in abundance and easily accessible i.e. “FLY ASH”. Many researches have been done to utilize the fly ash for removal of heavy metal like Arsenic, Cadmium, and Nickle etc. for the past years. This paper is based on the idea of utilization of the magnetic property of the Nano iron particles present in the fly ash as well as the adsorption capacity of the carbon particles present in the fly ash. The magnetic property harnessed by the means of magnetic filtration lead to a decrease in the settlement time of the sludge to 35 seconds in 1000ml of wastewater with a fly ash concentration of 12 g/l. Turbidity removal was 95% in most cases at variable settlement time. The wastewater used for the experiment/study was obtained from an Educational University in Gandhinagar, having various organic and inorganic contents. This sewage water initially having an over range turbidity which was reduced to a limit of 50 to 100 NTU by Fly ash treatment process induced with magnetic filtration. Atomic spectrometric test for Fe+ ions was done and the result obtained has slight decrease in the Fe+ concentration in the treated water. The whole treatment process done by the adopted method lead to a huge decrease of time span for treatment as compared with the standard adopted process for the treatment of sewage water at the university treatment plant.
