Description:
Seeded water treatment by high gradient magnetic separation techniques was carried out on combined storm overflows and raw sewage influents. Both bench-type and continuous pilot plant tests were performed to evaluate the effectiveness of the process in purifying waste waters. Critical parameters were varied to determine optimal removal efficiencies, sensitivities and relative importances of these variables. Attempts were also made to compare the effectiveness and economic feasibility of high gradient magnetic separation treatment with present methods of waste water treatment. Finally, recommendations for the next phase of study have been presented. The results of the present study show this process to be a highly effective method of reducing most forms of pollutants present in CSO and raw sewage to low levels of contamination. Capital cost estimates for high gradient magnetic separation systems also compare favorably with traditional secondary plants.
