“…During the process, the BTEX compounds diffuse into the biofilm, where they are metabolized by the microorganisms. Mello et al (2019) achieved 99% removal efficiency by applying attached biomass-supported activated carbon media [12]. The same reduction rate was achieved in horizontal-flow anaerobic immobilized biomass reactors where a denitrifying consortium was used as an inoculum to form a biofilm [13,14].…”

Benzene, toluene, ethylbenzene and xylenes, collectively known as BTEX compounds, are significant emerging contaminants in municipal wastewater. Stricter effluent quality regulations necessitate their removal, especially with concerns about organic micropollutant concentrations. Water scarcity further underscores the need for wastewater treatment to ensure safe agricultural or drinking water supplies. Although biological treatment partially reduces BTEX levels through processes like biodegradation and sorption, additional purification using physico-chemical methods is crucial for substantial reduction. This paper aims to outline plant-wide simulation methods for treating BTEX-contaminated sewage and facilitating reuse, adhering to IWA Good Modelling Practice Guidelines. The model, built upon the MiniSumo process model, incorporates equations detailing BTEX metabolism and removal kinetics, informed by an extensive literature review. Using a variant of the Benchmark Simulation Model with granular activated carbon for water reuse, the study examines strategies for improving effluent quality and minimizing operational costs. These strategies include adjusting the sludge retention time and airflow to enhance BTEX degradation and stripping, respectively, and comparing maintenance approaches for the GAC tower.

“…Activated carbon can also be used in supporting biofilms for pollutant removal. Due to the larger surface area provided by activated carbon, biomass was able to degrade xylene and other BTEX compounds efficiently and reduce the toxicity of up to 99% (Mello et al, 2019). In this era of machine learning, modeling strategy to check the efficient substrates of adsorption of SOCs can help in the development of efficient adsorbents.…”

Synthetic organic compounds (SOCs) are reported as xenobiotics compounds contaminating the environment from various sources including waste from the pulp and paper industries: Since the demand and production of paper is growing increasingly, the release of paper and pulp industrial waste consisting of SOCs is also increasing the SOCs’ pollution in natural reservoirs to create environmental pollution. In pulp and paper industries, the SOCs viz. phenol compounds, furans, dioxins, benzene compounds etc. are produced during bleaching phase of pulp treatment and they are principal components of industrial discharge. This review gives an overview of various biotechnological interventions for paper mill waste effluent management and elimination strategies. Further, the review also gives the insight overview of various ways to restrict SOCs release in natural reservoirs, its limitations and integrated approaches for SOCs bioremediation using engineered microbial approaches. Furthermore, it gives a brief overview of the sustainable remediation of SOCs via genetically modified biological agents, including bioengineering system innovation at industry level before waste discharge.

“…Anaerobic expanded granular sludge bed bioreactor and aerobic activated sludge (AS) bioreactor were the main treatment processes, exhibiting good removal in COD and organics. Batch and continuous bioreactors of biofilms supported on activated carbon were used to study the biodegradation of BTEX compounds from petrochemical wastewater (Muneron Mello et al, 2019). Complete degradation of BTEX compounds was achieved by the well‐adapted biofilms.…”

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.
