Three types of energy recovery devices (ERDs), including turbine ERD, pressure exchanger ERD, and dual-cylinder work exchanger ERD, are analyzed in single-stage, inter-stage pressurized, and dual-stage systems. Using WAVE software and thermodynamic modeling, the specific energy consumption (SEC) of each system is evaluated. The Gibbs model and ion model are applied to calculate exergy flows and destruction rates within the systems. Results indicate that dual-stage systems incorporating optimized ERD combinations reduce SEC by 15–25% compared to single-stage systems, achieving SEC values as low as 2.5 kWh/m<sup>3</sup>. Exergy analysis reveals that RO membranes contribute 55–95% of exergy destruction. Economically, dual-stage systems exhibit higher initial costs but yield long-term savings due to enhanced energy recovery efficiency. Notably, the dual-turbine configuration balances SEC (2.5–3.5 kWh/m<sup>3</sup>) and operational stability, providing the most cost-effective solution. The findings provide actionable insights for designing energy-efficient and economically viable RO desalination plants. The study underscores the importance of integrated energy, exergy, and economic analyses in optimizing RO desalination processes, potentially surpassing standalone ERD performance limits.</div></div>","PeriodicalId":56019,"journal":{"name":"Sustainable Energy Technologies and Assessments","volume":"93 ","pages":"Article 105372"},"PeriodicalIF":7.4,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148952601","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Applied to all ten water companies providing wastewater services in England and Wales over the 2020–25 regulatory period results show that the sector operates at approximately half its potential energy cost efficiency (mean BEPI = 0.496). Persistent structural inefficiency, rooted in legacy digestion infrastructure and plant configuration, consistently dominates transient operational inefficiency across all companies, indicating that capital investment rather than operational adjustment is the primary lever for efficiency improvement. Translating BEPI scores into monetary terms reveals a cumulative potential saving of £475 million over the five-year period.
