Ethyl centralite was investigated as to susceptibility to microbial degradation and/or biotransformation under both aerobic and anaerobic conditions in both static (batch) and continuous culture systems.
centralite was reduced under aerobic conditions in static culture to
approximately 35% of initial concentration after 5 days. N-ethylaniline
and Ethylphenylurea were identified as transformation products. However
the substance appeared to be quite stable to anaerobic degradation in
study has demonstrated that, in the presence of a rich nutrient medium,
the compound Centralite (diethyldiphenylurea) is biotransformed. These
results suggest that the compound may be successfully removed in a
continuous treatment process operated in both aerobic and anaerobic
modes. High nitrate concentrations are reduced to acceptable levels.
Although increasing the concentrations of nutrients or carbon source
supplements increased the disappearance of a compound it is hoped that
suitable adjustments in operating parameters of a continuous system
would make it possible to drive the disappearance to completion.
