Removal of Phenol from Sewage Effluent

What is it about?

Treatment of hazardous phenolic substances that are discharged to environment has a significant interest since decades. Biological treatment using freely suspended sludge is the most economical treatment method, but, is considered inactive for treatment of phenolic substances due to the complexity in their chemical structure. The degradation of phenol was experimentally investigated using separate and coupled biological and photo-catalytic processes.

Why is it important?

The photo-catalytic degradation of phenol resulted in another toxic materials, longer exposure to UV would result complete degradation of phenol and its derivatives. Thus, despite the effectiveness of the combination of AOP and biological processes, photo-oxidation process is recommended as a post treatment to the biological wastewater treatment; other arrangement would lead to inefficient.
