Oxygen microprofiles were used to evaluate the relationship between organic loading and respiration rate. The oxygen fluxes into the biofilms represent the total aerobic reaction rate of the biofilm, and the total organic removals represent the total use rate of the biofilm. The ratios of respiration rate to total chemical oxygen demand (COD) removal rate were evaluated under various operational conditions. Results showed that an increase in oxygen supplied increased only the respiration rate and did not affect the overall COD use rate. Systems fed additionally with azo dyes (possible inhibitors) had lower organic removals. Azo dyes appeared to affect both the local respiration rate and the local COD removal rate inside the biofilm.
