“…The microscopic analysis showed that a good biofilm coverage was obtained and that the biofilm uniformity was also remarkable. This performance was reported earlier by Ahmed et al (2019c). It is also worth mentioning that no clogging problems were encountered during the reactor operation.…”

The wastewater characteristics and some operational control parameters limit the efficiency of attached growth processes for petrochemical wastewater treatment. This study aims to determine the efficiency of a hybrid biological reactor treating actual petrochemical wastewater and to identify the efficiency determining factors. An up-flow biological reactor filled with bio-career was operated at two flow rates, two dissolved oxygen (DO) levels, and under anaerobic conditions. Due to the varying characteristics of actual petrochemical wastewater, efficiency limitations were manifested in many ways. However, the highest chemical oxygen demand and biochemical oxygen demand (BOD) removal efficiencies were 77.2% and 78.5%, respectively, and were achieved under aerobic operation at organic loading rates (OLRs) of 0.2 kg-COD/m3/d and hydraulic retention time (HRT) of 26.67 h (DO 4.0 mg/l). Anaerobically, the highest efficiency was 41.7 for both at 0.18 kg-COD/m3/d and 400 ml/min. The total organic carbon (TOC) removal stability was attributed to the presence of toxic chemicals and removal mechanisms other than biodegradation, as it tapered off at high loading. The nutrient removal efficiency was marginal, conceivably due to the high organics to nutrient ratio and toxic conditions of the wastewater promoting nutrient removal inside the biofilm.

“…The isolated strains demonstrated the halotolerant capability and achieved COD removal of 77%. Granular activated carbon was integrated into a fixed‐film activated sludge process as the support media to enhance the biodegradation of organics and nutrients in petrochemical wastewater (Ahmed, Mydlarczyk, & Abusam, 2019). The integrated system was effective in treating COD and nutrients (N and P).…”

Petrochemical wastewater and produced water from oil and gas operations typically contain an array of organic and inorganic contaminants. The complexity of the wastewater, stringent environmental regulations, and the need for sustainable solutions have driven many research efforts in studying and developing advanced technology or combined treatment processes. On the other hand, the wastewater itself can be resources for water, energy, and other valuable product if appropriate technology is developed to recover them in a cost-effective fashion. The research advances in wastewater treatment and resource recovery technology are reviewed and summarized. For petrochemical wastewater, progresses were made in advanced oxidation, biological processes, and recovery of energy and water from wastewater. For produced water, many efforts were focused on membrane processes, combined systems, and biological treatment.
