摘要: A method of treating sewage sludge comprises a pathogen reduction stage in which raw is incubated for predetermined incubation period at temperature the mesophilic range. The plurality sequential vessels ( 1 a, b, c ) comprising an upstream vessel receives to be and downstream discharges sludge. fed from ), via any intermediate b subsequently discharged after spending residence time each vessel, total being said period.
