Research progress on life cycle assessment of end-of-life reverse osmosis membrane
Reverse osmosis(RO)technology is widely used in the field of water treatment,and plays an important role in desalination and wastewater treatment.While the scale of RO technology is expanding,a large number of end-of-life RO membranes are generated,most of which are disposed of in landfills or incinerated,causing environmental pollution and wasting resources at the same time.The current methods of managing end-of-life RO membranes,including reuse,recycling and energy recovery,were outlined according to the waste management hierarchy.And the current life cycle assessment(LCA)research on the abandonment stage of RO membranes was analyzed based on the LCA framework.The results indicate that the management of end-of-life RO membranes improves the sustainability of RO desalination,is an effective alternative to landfill,and is an effective way to introduce circular economy into RO membranes.Currently,the LCA for the management of end-of-life RO membranes is still in its infancy.It is urgent to carry out the life cycle assessment of emerging end-of-life RO membranes management technology,as well as the comparative life cycle assessment of the management of end-of-life RO membranes.
