Conclusions from ModelingConclusions from Modeling The lava rock-based biofilter is efficient
for treating odorous H2S.
The biofiltration model, which has been incorporated into a friendly software (BiofilterTM), is capable of predicting the biofilter removal performance of H2S.
The model is a useful tool for biofilter design and operation.
