Effectiveness of Biosurfactant for Toluene Removal in Biotrickling Filters Operating under Stressed Operating Conditions

摘要

1.Rhamnolipids can replace bed backwashing as a technique to control excessive biomass growth 2.Rhamnolipids stabilized pressure drop across the BTF 3.Selected rhamnolipids concentration did not exhibit any toxicity on microorganisms in the BTF 4.Stable long-term scenario of a BTF working under stressed operation conditions is achievable in the presence of biosurfactants 5.Higher toluene loading rates and carbon mass balance are under investigation.
