“…Advances in the design and development of highly efficient adsorbents have intensified in the recent years. Different literature reports and critical reviews address the application of different adsorbents for water contaminant capture including activated carbon, carbon nanomaterials (graphene, fullerenes, nanotubes), zeolites, inorganic materials (e.g., MoS 2 , CeO 2 ), metal‐organic frameworks (MOFs), molecularly imprinted polymers (MIPs), porous organic polymers (POPs), and hybrid membranes …”

“…Activated carbon is one of the most reported commercially available materials for removing pollutants from water, since it is inexpensive and features large surface area. However, although many forms of activated carbon are currently used in water treatment featuring relatively high removal efficiencies for a great number of microcontaminants, adsorption of hydrophilic contaminants is quite limited .…”

Covalent organic frameworks (COFs) are attractive materials receiving increasing interest in the literature due to their crystallinity, large surface area, and pore uniformity. Their properties can be tailored towards specific applications by judicious design of COF building blocks, giving access to tailor‐made pore sizes and surfaces. In this Concept article, developments in the field of COFs that have allowed these materials to be explored for contaminant adsorption are discussed. Strategies to obtain water‐stable materials with highly ordered structures and large surface areas are reviewed. Post‐synthetic modification approaches, by which pore surfaces can be tuned to target specific contaminants, are described. Recent advances in COF formulations, crucial for future implementation in adsorption devices, are highlighted. At the end, future challenges which need to be addressed to allow for the deployment of COFs for the capture of water contaminants will be discussed.

“…Due to its adsorbent properties activated carbon (AC) can efficiently remove organic micropollutants (OMPs) from wastewater (Çeçen and Aktaş, 2012;Wang and Wang, 2016). OMPs are found in sewage water treatment systems and one of the main sources are pharmaceuticals originating from households, livestock farming and hospital effluents (Mansour et al, 2018). The detection of OMPs in surface waters indicates that the present treatment at waste water treatment plants (WWTPs) is insufficient to remove OMPs effectively (UBA, 2015), hence legal regulations are already in force in Switzerland for the implementation of a fourth treatment stage at WWTPs (FOEN, 2015).…”

Activated carbon (AC) used for removal of organic micropollutants in European wastewater treatment plants (WWTPs) is usually produced from non-renewable resources that need to be transported over long distances. Utilising local residual biomass as a raw material may be advantageous in terms of sustainability. This study investigated the environmental and energy balances of using biowaste and biomass from landscape management for micropollutant removal at a commercial scale WWTP. Both residual biomasses were processed using the integrated generation of solid fuel and biogas from biomass (IFBB) technique to obtain a press cake that was used as feedstock for AC production. The results showed a lower global warming potential (GWP) and cumulative energy demand in comparison to a fossil-based conventional AC. Differences in GWP between residual and fossil ACs were enhanced when the end-of-life incineration step was considered, and residual AC had a lower social risk associated with its production. Energy efficiency of AC production was substantially increased by utilising waste heat generated in the pyrolysis process of biochar and by using electricity generated in a combined heat and power plant using biogas from the methanation of IFBB press fluids. Converting residual biomass into activated carbon using IFBB and a state-of-the-art pyrolysis and activation unit along with energy recovery would aid WWTPs to become self-sufficient in terms of raw materials and improve the sustainability of WWTPs.

“…The adsorption of PCs on BCs may be affected by the pH, contact time, temperature, sorbent particle size and amount, as well as by the properties of the particular PCs [13,14]. Experiments regarding the removal of triclosan from secondary WW effluent using wood-based BC in continuous flowthrough columns indicated adsorption of triclosan by BC, but to a lesser extent than by activated carbon [15].…”

The aim of this study was to evaluate the effectiveness of wood-derived biochar for the removal of 18 pharmaceutical compounds (PCs) from untreated municipal wastewater (WW). The WW samples were analyzed by an HPLC-Q-Orbitrap-HRMS method. Two aliquots of WWs were incubated with biochar sorbent for 2 h and 7 d. The highest absolute removal of PCs was achieved for ibuprofen and caffeine (2.6 and 13.2 mg L-1 after 7 d, respectively). The highest removal efficiency after 2 h incubation was detected for erythromycin (72.0% ± 12.7 %) while lower degree of removal was observed for other compounds with much higher initial concentrations. The results indicated that a 2 h sorption process on biochar may be insufficient and 7 d incubation is preferred for quantitative removal of xylazine, metoprolol, and azithromycin. However, the sorption of ketoprofen, diclofenac, ibuprofen, sulfamethoxazole, and simvastatin on biochar was more effective during the first 2 h than during the following 7 d. Regression analysis revealed a strong correlation (R 2~0 .9) between the absolute amounts of the removed PCs and their initial concentrations. In this respect, the removal of the last traces of PCs from WW is expected to present technological challenges.
