Effect of ferrous sulfate and peracetic acid on the properties of activated sludge
An activated sludge was treated with Fe-2(SO4)(3) (5-7 g/kg dry mass) and AcOOH (0.15-0.75 mg/kg dry mass) to change the suspension content, sediment index and d. index of the sludge. The addn. resulted in decrease of the biotic sediment index but did not result in any substantial decrease in the filamentous bacteria no.
