Abstract

Phenol is generated in many industries, including oil refineries, production of phenolic resins, plastics, coal furnace, tannery, textile, rubber and processing seafood, and rubber reclamation plants. The presence of phenol in wastewater of oil refineries, petrochemical plants, olive oil, pesticide generation and oil field activity is primarily associated with the TDS. This study is aimed to determine the effectiveness of moving bed biological reactor (MBBR) for removing the phenol from saline wastewater. The MBBR used in this work was operated with HRT of 6 hours for 233 days. Effect of phenol concentration (0-500 mg/L) on the MBBR performance was conducted in three phases. MBBR performance by the phenol concentration of 100 mg/L was not affected. So that the COD removal efficiency for phenol and COD, was 95.5-97% and 94%, respectively. MBBR reactor by the phenol concentration of 300 mg/L and 500 mg/L are affected. Removal efficiency for phenol 94.5-96.5% and 92-94.5%, respectively. MBBR reactor removal efficiency for salinity 2% and 3% 86-89% and 82-85.5%respectively it can be deduced that the effect of salinity changes on system performance more than phenol change. Moving bed biofilm reactor (MBBR) is able to remove the phenol from saline wastewater.
