Inhibitory chemicals for biological wastewater treatment
Understanding which compounds have a negative impact on your plant’s biological treatment system is key to effective treatment
Biological treatment of wastewater is dependent on a complex, interdependent microbial community existing in the biomass. For effective treatment, this community must perform properly; however, there are a number of affecting factors.
The structure and composition of the biomass are very sensitive to sudden changes in environmental factors—for example, pH and temperature. Furthermore, there are a number of toxic or inhibitory compounds that hinder the effectiveness of these microbes at performing essential tasks, like biodegradation.
To ensure that the existing microbial community is performing as expected, it is important to understand which compounds, and at which concentrations, are going to have a negative impact on your plant’s biological treatment system.
