Extending the life-cycle of reverse osmosis membranes: A review

Abstract: The reverse osmosis (RO) technology for desalination and demineralization serves the global water crisis context, both technically and economically, and its market is growing. However, RO membranes have a limited life-cycle and are often disposed of in landfills. The impacts caused by the disposal of thousands of tonnes per annum of RO membranes have grown dramatically around the world. Waste prevention should have a high priority and take effect before the end-of-life phase of a product is reached. In this re… Show more

“…We used the capital cost estimator tool on Desaldata [82] According to DesalData [82], membrane capital cost is approximately 6.5% of the total system CapEx. We selected a membrane lifetime of 5 years, based on the 3-7 year range in the literature [83]. Consequently, the membranes must be replaced twice during the project duration at the 5-year…”

“…Several factors affect TFC RO membranes lifetime (5 -7 years), one of which is the formation of fouling layer. The fouling is produced as a results of the removal of dissolved matter and particles in the feed, which can be classified as inorganic, organic and biological fouling [1].The disposal of TFC RO membranes after the end of their lifetime has negative effects on the environment, because most often EoL RO modules are incinerated to recover energy [2] or discharged in landfills. According to Landaburu-Aguirre et al [3] and the latest data of the International Desalination Association (IDA) [4], the total mass of disposed modules was estimated to be more than 16,500 tons in 2018, which indicates that the problem of disposed membranes needs urgent attention.…”

“…This is because reusing has also economic interests and not just environmental benefits [6]. Direct reuse is divided into three categories: (1) rejuvenation of EoL membranes, (2) using for lower grade treatment and (3) using for new applications [5]. The rejuvenating treatment is done by cleaning agents in order to remove most of the fouling and scaling [7].…”

“…The study period for the LCA was 1 year to neglect any effects of maintenance or repair and to focus solely on the environmental impacts due to system operations. The MF, UF, and RO membranes were replaced at a rate of 1/10th of the total membranes per year due to their 10-year lifespan [43,44]. The MD membranes were replaced at a rate of 1/5th of the total membranes per year due to their 5-year lifespan, as used in other LCA studies [30].…”
