This study investigates the application of a pulsed electric field (PEF) mode in ED for the treatment of model and real refinery wastewater. PEF is a promising method for intensifying mass transfer and mitigating polarisation phenomena in the presence of complex mixtures of salts, petroleum products, and surfactants. Key parameters - average current density (5-10 mA/cm<sup>2</sup>), frequency (500 ± 20 Hz), and duty cycle (2) - were optimised to minimise specific energy consumption and membrane scaling. The novelty of this research lies in the comparative analysis of pH stability and energy efficiency between DC and PEF modes under high-fouling conditions typical of the oil and gas industry. Compared to direct current (DC) at the same average current density, the PEF mode reduced specific energy consumption by 1.2-2.2 times and increased the desalination rate by 1.6-2.0 times. Furthermore, PEF mode stabilised the pH in the concentrating chamber, leading to a significant reduction in inorganic scaling, as confirmed by qualitative and quantitative observations. High removal efficiency of heavy metal ions (Fe, Cr) were achieved at the optimal pulse frequency.

Two experimental phases were conducted: (i) assessing traditional sludge under increasing salinity, and (ii) evaluating acclimated sludge at higher salinity (1.25%).

After 21 days of acclimation (0.25% and 0.5%), COD and NH<sub>4</sub><sup>+</sup> removal efficiencies improved to 11-13% and 22-25%, respectively, under 1.25% salinity. Microbial analysis revealed a decline in bacterial richness with increasing salinity. Concurrently, halotolerant and halophilic microorganisms were selectively enriched. These findings support the application of salinity-acclimated sludge as seed biomass for saline domestic wastewater treatment in WWTPs.</p>","PeriodicalId":12009,"journal":{"name":"Environmental Technology","volume":" ","pages":"2294-2306"},"PeriodicalIF":2.2,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147835589","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
