“…By adding 0.5% of methylcellulose and 2.5% of activated carbon, the porosity and the rejection rate achieved up to 85.38% and 41.57% for 10 ppm of paracetamol. By using the inversion technique, ZnO can be attached to the polyethersulfone resulting in C=C bond breakage and 90.24% of paracetamol degradation for 5 mL concentration and 86.18% for 10 mL concentration that the transformation of paracetamol is possible drawn as seen in Figure 2b [ 75 ]. In the sole solution, the nanofiltration NF50 membrane removed 36% of paracetamol at pH 12 and 12.2% at pH 3 [ 76 ].…”

Membrane technology can play a suitable role in removing pharmaceutical active compounds since it requires low energy and simple operation. Even though membrane technology has progressed for wastewater applications nowadays, modifying membranes to achieve the strong desired membrane performance is still needed. Thus, this study overviews a comprehensive insight into the application of modified polymer membranes to remove pharmaceutical active compounds from wastewater. Biotoxicity of pharmaceutical active compounds is first prescribed to gain deep insight into how membranes can remove pharmaceutical active compounds from wastewater. Then, the behavior of the diffusion mechanism can be concisely determined using mass transfer factor model that represented by β and B with value up to 2.004 g h mg −1 and 1.833 mg g −1 for organic compounds including pharmaceutical active compounds. The model refers to the adsorption of solute to attach onto acceptor sites of the membrane surface, external mass transport of solute materials from the bulk liquid to the membrane surface, and internal mass transfer to diffuse a solute toward acceptor sites of the membrane surface with evidenced up to 0.999. Different pharmaceutical compounds have different solubility and relates to the membrane hydrophilicity properties and mechanisms. Ultimately, challenges and future recommendations have been presented to view the future need to enhance membrane performance regarding fouling mitigation and recovering compounds. Afterwards, the discussion of this study is projected to play a critical role in advance of better-quality membrane technologies for removing pharmaceutical active compounds from wastewater in an eco-friendly strategy and without damaging the ecosystem.
