“…The conventional activated sludge and membrane bioreactor processes can efficiently remove bulk organics, nutrients and pathogens. However, certain groups of PPCPs such as significantly hydrophilic compounds and/or compounds with strong electron withdrawing functional groups are poorly removed by the conventional biological treatment processes [2,15,16,17]. Thus, effective treatment processes to remove PPCPs from wastewater is urgently needed.…”

White-rot fungi (WRF) mediated treatment can offer an environmentally friendly platform for the removal of pharmaceuticals and personal care products (PPCPs) from wastewater. These PPCPs may have adverse impacts on aquatic organisms and even human and thus their removal during wastewater treatment is of significant interest to the water industry. Whole-cell WRF or their extracellular lignin modifying enzymes (LMEs) have been reported to efficiently degrade PPCPs that are persistent to conventional activated sludge process. WRF mediated treatment of PPCPs depends on a number of factors including physicochemical properties of PPCPs (e.g., hydrophobicity and chemical structure) and wastewater matrix (e.g., pH, temperature, and dissolved constituents), type of WRF species and their specific extracellular enzymes. This review critically analyzes the performance of whole-cell WRF and their LMEs for the removal of PPCPs; particularly, it offers insights into PPCP removal mechanisms (e.g., biosorption vs. biodegradation) and degradation pathways as well as the formation of intermediate byproducts.

“…(2009) obtain 65%, Vieno & Sillanpää (2014) report 23-85, Moya-Llamas et al (2018 obtain 30-75%. In our investigation, the average removal of DCF reached 86%, which might be due to the elevated age of the sludge (SRT) being over 90 days, which allowed the bacterial population to be more diversified and to be able to degrade DCF, either by direct metabolism or by co-metabolic degradation through enzymatic reactions (Vieno & Sillanpää 2014;Hai et al 2015). Consistent with this rationale, Asif et al (2019) report removals for DCF of 50% for SRT of 30 days, and of more than 90% for SRT of 80 days.…”

This study employs a novel combined pilot plant consisting of an anaerobic reactor followed by a membrane electro-bioreactor (eMBR) to treat domestic water containing selected micro-pollutants of emerging concern (CECs) [ibuprofen (IB), carbamazepine, diclofenac (DCF) and 17α-ethinylestradiol (EE2)]. The first phase operated as a conventional membrane bioreactor to achieve the removal of organic matter [chemical oxygen demand (COD)], the CECs and phosphorus. A removal rate of 96.3% for COD, 94.5% for IB, 37.1% for CMZ, 87.1% for DCF and 96% for EE2 was obtained. In the three subsequent phases, current density (CD) of 5, 10 and 15 A/m2 was applied successively in the eMBR with the aim of investigating the effects on the removal of the former components and the fouling of the membrane. After the application of 5 and 10 A/m2 CD, the removal rate of COD decreased. Regarding phosphorus, a CD of 5 A/m2 was enough to achieve the rate of 97% and the membrane fouling suffered a substantial reduction too. Finally, the experimental results were subject to statistical analysis using the Kruskal–Wallis and Wilcoxon tests to validate the influence of each DC.

“…Combined or hybrid treatment options are also conceptually beneficial, usually leading to improved treatment efficiencies [235][236][237]. Examples of possible combined/hybrid water treatment processes include membrane filtration followed by activated carbon, MBR followed by activated carbon, activated carbon adsorption followed by UV, integrated MBR-TiO 2 photocatalysis, and integrated MBR-PAC adsorption.…”
