Biotreatability <br /> Biotreatability investigations typically are performed following they:determination of project <br /> feasibility and are designed to characterize the microbiological and physicochemical criteria <br /> required during implementation to ensure optimal process performance and cleanup kinetics. <br /> The evaluations typically are performed using bench and/or field-scale model systems and are <br /> r designed to simulate biotreatment under site-specific conditions. <br /> �. Biotreatability analyses can be provided through BioLogic in a timely and economic manner. <br /> r- Reports generated from these investigations include data':interpretation and practical recom- <br /> mendations designed to ensure the success of the remediation and/or waste minimization <br /> project. Several of the evaluations typically performed in a biotreatability investigation may <br /> include: <br /> Biotreatability Investigation parameters <br /> 0 Basic nutrient physicochemistry H Bioaugmentation/biostimulation <br /> 0 Selective degrader identification a Precipitant evaluations ()vater) <br /> 0 Microbial enumeration and 0 Effects of physicochemical <br /> composition parameters <br /> P � l <br /> 0 Synergistic/antagonistic Q Effects of surfactants <br /> microbial interactions Q Effects of nutrient additives <br /> Microbial biodegrader screen Q Microbial kinetics assessment <br /> assessment <br /> r' <br /> s :. <br /> Biofouling Assessment -qp <br /> Biofouling is a condition associated with tight soils where ,interparticle plugging results from <br /> subsurface bacterial growth and biomass formation. Biofouling can develop quickly and just <br /> as quickly "foul", sometimes irreversibly, an in situ project. A propensity toward biofouling <br /> can be addressed in a biotreatability investigation where in situ model systems containing <br />` site-specific soill are constructed to determine whether bi4ouling will occur and/or to what <br /> point bioremediation will be effective, if at all. The data generated in a biofouling assessment <br /> will aid the client in making feasibility decisions as to the 'appropriateness of bioremediation <br /> for the project site. <br /> 7 <br /> / <br />
