Conventional energy buffering methods, using electrical storage (batteries or supercapacitors) or mechanical storage (pressure accumulators), provide only temporary buffering, however, cannot prevent pump shutdowns. Direct control of PV-membrane hydrodynamics, independent of energy buffering systems, remains an underexplored solution to this issue. In this study, an electrohydraulic control system (EHCS) was developed to dynamically minimise pump shutdowns during unfavorable weather conditions across different membrane types. The system achieves this by rapidly reducing the load pressure on the pump via fast-response control actions using an electrically actuated valve. Experimental results demonstrate that the EHCS (without buffering support) increased daily water production by 7.5 % for the BW30 membrane and 14.6 % for the NF90 membrane under highly cloudy conditions. Additionally, pump shutdowns were reduced by 86 % for the BW30 membrane and 57 % for the NF90 membrane. The findings highlight the EHCS as an effective alternative for managing PV-membrane system performance during SI fluctuations, offering a robust solution without reliance on energy buffering systems.</div></div>","PeriodicalId":299,"journal":{"name":"Desalination","volume":"608 ","pages":"Article 118784"},"PeriodicalIF":8.3,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143725075","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Over-abstraction from these aquifers accelerates SWI, necessitating practical measures to prevent it and enable sustainable extraction of groundwater resources. Simulation-optimization (S/O) methods have been widely adopted for developing optimized groundwater extraction strategies, with optimization algorithms playing a critical role. This study compared several constrained multi-objective optimization algorithms (CMOOAs) for designing pumping schemes to mitigate SWI in coastal aquifers. The evaluated algorithms included the Controlled Elitist Multi-Objective Genetic Algorithm (CEMOGA), Multi-Objective Feasibility Enhanced Particle Swarm Optimization (MOFEPSO), Multi-Objective Lichtenberg Algorithm (MOLA), and Multi-Objective Pareto Search (MOPS). A bi-objective SWI management model was developed using an S/O approach, with the FEMWATER code replaced by a surrogate model based on Multivariate Adaptive Regression Spline (MARS) to improve computational efficiency. The MARS model effectively captured aquifer processes, demonstrating strong correlation metrics (R = 0.986–0.999) and low error indicators (NRMSE = 0.001–0.019, MAE = 0.522–6.291 mg/l). This surrogate model was integrated with each CMOOA to design optimal pumping strategies that maximize beneficial abstraction while minimizing SWI. Multiple independent MARS-assisted optimization runs were conducted for a robust comparison of solution accuracy and convergence time. Results showed that MARS-CEMOGA outperformed other algorithms, delivering the highest solution quality and computational efficiency, requiring just 323.86 s compared to 388.12 s for MOPS, 999.18 s for MOFEPSO, and 2316.55 s for MOLA.

The ICC mode shows the highest specific energy consumption (up to 72.02 Wh/mol of NaCl at 2.0 V) and low operational stability manifested by extreme alteration of pH in the electrode compartments (anode compartment pH down to 2.17; cathode compartment pH up to 12.08), which leads to the need for frequent electrode regeneration or replacement. In comparison to the ICC mode, the SCC mode exhibited superior performance, with a 44.3 % increase in salt removal and up to 3.95 % higher current efficiency at 2.0 V, due to the regeneration of electrodes through short-circuiting, as it reduces the electrical resistance and minimises the side reactions.
