Slurry treatment is an innovative approach for bioremediation of contaminated soils under controlled conditions of pH, temperature, and nutrients. This treatment of excavated soils permits better control of environmental conditions than in landfarming, composting, and biocell units, and therefore may achieve accelerated rates of decontamination. Bioslurry reactors have been used to remediate a variety of contaminants, such as soils and sludges from refinery wastes, wood-preserving wastes, wastes containing polychlorinated biphenyls and halogenated solvents. Key considerations in design of such reactors involve meeting the oxygen requirements for biodegradation, preventing the settling of soil particles, efficient mixing of additives, and control of foaming. The aspects of reactor design, specifically agitation system have been discussed in this paper.
