Biofilter with modular trays
摘要:
A biofilter for the removal of contaminants from gas streams disclosed. The biofilter makes use of a series of modular trays, each containing a gas-contacting medium for removing at least one contaminant from the process stream. The trays have a modular design that allows them to be sealingly stacked and to be configured to allow series, parallel or series-parallel flow through the biofilter.
