Nevertheless, the current disposal practices for these end-of-life (EoL) polymeric membranes, primarily landfill and incineration, are neither economically nor environmentally sustainable. To address this challenge, we first analyzed the factors leading to the EoL phase for these membranes; an understanding that is critical in developing or selecting appropriate recycling technologies. We further proposed a technological framework to guide recycling choices based on the specific state of the EoL membrane. In cases where the membrane exhibits significant breakage, dissolution using eco-friendly solvents, followed by membrane re-preparation, is recommended. For membranes without substantial breakage, regeneration, upcycling, or downcycling strategies can be deployed based on scenarios. We underscored the crucial role of irrecoverable foulant removal within the regeneration technology. Additionally, the reaction interface must be suitably remediated before the application of upcycling technology to EoL microfiltration/ultrafiltration membranes. The downcycling strategy, facilitated by NaOCl oxidation, is readily applicable to EoL nanofiltration/reverse osmosis membranes.

In this work, a seawater reverse osmosis (SWRO) membrane with powerful boron removal competence was designed by adopting an in-situ rapid integration protocol, which utilized aliphatic amines as hydrophobic barriers by bonding the residual chloride groups upon the membrane surface and as molecular plugs by embedding in the PA networks. Consequently, it resulted in a notable improvement in the rejection of neutral boron molecules due to enhanced steric hindrance caused by immobilized amine plugs and synergistically tunned hydrophobic interactions. The permeability coefficient of boron decreased from 4.8 to 0.9 L m−2 h−1, and the boron rejection increased from 80.7 to 90.5% under the modification conditions with the optimal type and concentration of amines, while displaying a NaCl rejection of 99.8% and an acceptable water permeability of 0.55 L m−2 h−1 bar−1. Meanwhile, the alteration of membrane chemical compositions and structure properties was kept to a minimum.
