Biotreatment of Petrochemical Wastewater: A Case Study from Northern Tunisia
A full‐scale study has been conducted to assess the bioaugmentation efficiency of trickling filter process to treat petrochemical wastewater from a lubricant industry recycling waste oils. During 45 weeks, the organic loading rate (OLR) in the trickling filter was increased stepwise from 0.9 to 4 kg of chemical oxygen demand (COD)/(m3·day) at the end of the upgrading period as the flow rate (FR) reached the value of 30 m3/day. The removal, obtained in terms of percentage, for COD ranged from 60 to 84.5 and greater than 98 for total n‐alkane (TNA), while those of total kjeldahl nitrogen (TKN) and total phosphor (TP) were about 32 and 55, respectively. The analytical profile index (API) of trickling biofilm has confirmed that 5 strains are closely related to Acinobacter junii, Stenotrophomonas maltophilia, Vibrio vulnificus, Vibrio metschnikovi, Pseudomona slulzeri and Trichosporon spp2.
