“…MBR was estimated 0.03 $/m 3 lower than that reported for the MBR by Mannina et al The difference between data might be associated with the variability in the operational condition, MBR design, and wastewater flow rate. In the MBR systems, the higher operational cost is associated with the membrane module aeration because of its high-energy requirement (45%–75%) . Neoh et al pointed out that 10% of the MBR capital cost belonged to the membranes and 50% to the vessels.…”

A highly efficient, economic, and environmentally friendly hybrid membrane bioreactor-reverse osmosis (MBR-RO) was simulated for the treatment of meat-processing wastewater. The effluent elucidated ≥92% reduction in the COD, TKN, NO 3 − − N, TN, TSS, and TP parameters. The aerobic MBR accounted for over 62% of the total operation cost that predominantly dealt with the electricity demand (94.19%), while climate change (95.13%) and photochemical oxidation formation (4.66%) categories imposed the highest environmental burdens. Fossil fuel utilization as the major energy supplier (97.26%) significantly enhanced the CO 2 emission that led to augmented environmental impacts. Most sensitivity to change of prime parameters was reflected by the agricultural land occupation (19.25%) and ozone layer depletion (18.97%) categories. Accordingly, the proposed hybrid MBR-RO can be nominated as a promising system to overcome problems emerged from the meat-processing wastewater.

“…Currently, a plant‐wide modeling comparison revealed some better findings for the activated sludge system compared to membrane bioreactors. Specifically, the activated sludge system had lesser direct and indirect greenhouse gas emissions than membrane bioreactors (Mannina, Cosenza, & Rebouças, 2020).…”

Wastewater treatment plants (WWTPs) become a main contributor of polycyclic aromatic hydrocarbons (PAHs) and their substitutions present in freshwater systems. This paper reviews PAHs and their substitutions in full‐scale WWTPs including their fate and behaviors, analytical techniques, biological treatments, feasibility examination, and modeling. In addition, challenges and future outlook are also highlighted. This study found that PAHs and their substitutions have been detected in WWTPs. GC‐MS and HPLC analytical methods have been found to be acceptable for the detection and analysis of PAHs and their substitutions. Although some biological treatments such as activated sludge and membrane bioreactors are capable for the treatment process, their technical, social, economic, and environmental aspects must be considered. The fate and treatability estimator (FATE) model has been used for the modeling of removal of PAHs in full‐scale WWTPs, but in some cases their shortcoming has been reported, which calls for an evaluation and modification of the model based on physicochemical processes.

“…Membrane bioreactor (MBR) is a established process for removing microplastics from wastewaters in real WWTPs or pilot scales [67,98,109]. The removal efficiency of the MBR process in several studies conducted in the Netherlands, China, the United States, the United Kingdom, and Finland are in the range of 64.4 to 99.9% [12,13,67,109,116,117]. Membrane bioreactor is a growing technology in conventional water and wastewater treatment plants for replacing the conventional activated sludge technology in some countries such as Sweden.…”

Separation and removal of microplastic pollution from aquatic environments as a global environmental issue is classified as one of the major concerns in both water and wastewater treatment plants. Microplastics as polymeric particles less than 5 mm in at least one dimension are found with different shapes, chemical compositions, and sizes in soil, water, and sediments. Conventional treatment methods for organic separation have shown high removal efficiency for microplastics, while the separation of small microplastic particles, mainly less than 100 µm, in wastewater treatment plants is particularly challenging. This review aims to review the principle and application of different physical and chemical methods for the separation and removal of microplastic particles from aquatic environments, especially in water treatments process, with emphasis on some alternative and emerging separation methods. Advantages and disadvantages of conventional separation techniques such as clarification, sedimentation, floatation, activated sludge, sieving, filtration, and density separation are discussed. The advanced separation methods can be integrated with conventional techniques or utilize as a separate step for separating small microplastic particles. These advanced microplastic separation methods include membrane bioreactor, magnetic separation, micromachines, and degradation-based methods such as electrocatalysis, photocatalysis, biodegradation, and thermal degradation.
