Study on the Treatment of Excess Activated Sludge on the Return Sludge Line

Abstract

The motion of ferrite particles was used to treat the excess activated sludge produced in waste water treatment plants. The motion of ferrite particles was controlled by two electromagnets (EMs). We have proposed a magnetic circuit with two metal plates between the EMs, so that the magnetic flux of the magnets can be obtained for a larger area. Thus, a larger container with activated sludge can be treated and by applying an AC voltage to it, can be sterilized and its quantity can be reduced. Our experiments show the prospects of using magneto-ferrite treatment in the return line of activated sludge in a sewerage plant.
