Designing a modular biofilter for cleaning gas emissions

Summary

The issues of designing a modular biofilter for cleaning air polluted with aromatic hydrocarbons are considered. The technology of air cleaning using biofiltration was tested earlier at a pilot plant. Basing on the analysis of various biofilter designs and taking into account the high required air capacity of the industrial unit (70,000 m³/h), an option was adopted with prefabricated separate modular biofilters in the form of heat-insulated containers with dimensions providing for the delivery to the assembly platform by regular transport. The required capacity is achieved by parallel connection of the required number of individual apparatus. To identify possible design flaws, a full-scale biofilter was fabricated and tested. The identified negative factors were eliminated in the industrial modular biofilter project.
