Oil spills and industrial pollution pose a huge threat to the ecological environment. Concerns over safety have seen an increased focus on improving the filtration of oily wastewater; for example, during the treatment of sewage. Membrane separation technology offers a promising and efficient option for treating that wastewater, particularly with its low energy consumption. However, it remains a challenge to find low-cost, strong and environmentally-friendly composite membranes that can achieve a high level of separation.
