A method for improved slurry-phase bioremediatian treat- ment of organic sludge and mix- tures of organic sludge and organ- ics-contaminated soils by dissolv- ing the contaminants into an aque- ous phase and microbially degrad- ing same. A high solids slurry of the sludge and soils is formed with water and an active bio-slurry con- sisting of large populations of ac- climated hydrocarbon-utilizing bacteria and small amounts of bi- odegradation residue. The slurry is passed through a plurality of in- series bioreactors (2-6) in each of which a low hydraulic shear is maintained to promote the devel- opment of a large population of microorganisms that will form flocculent suspensions. The output from the series of bioreactors is flowed continuously or semicontinuously to a liquid-solids separator (7) to partition the mixed liquor bio-slurry from the biode- graded waste residue. The mixed liquor bio-slurry containing small amounts o f biodegradation residue is returned to the slurry being processed for recycli
