Evaluation of cellulose triacetate hollow fiber membrane for volume reduction of real industrial effluents through an osmotic concentration process: A pilot-scale study

The current article tackles the challenge of reducing wastewater volumes generated from gas industry. A forward osmosis (FO) pilot unit, deployed as osmotic concentration (OC) process without draw solution (DS) recovery step, was applied an option for volume reduction real industrial effluents. commercial hollow fiber (HF) FO membrane fabricated Cellulose Triacetate (CTA) firstly tested with synthetic feed (FS) to investigate separation properties and identify optimum operating conditions unit. plant then challenged extended period operation, primarily assess membrane-fouling propensities other performance parameters. Results revealed that according conditions, CTA can achieve recoveries between 60%–90%, at water fluxes 2.24-1.65 L.m ?2 h ?1 (LMH)). operation 75% identified condition since it showed lowest specific solute flux (20.93 mmol L ) a 1.94 LMH. Outcomes testing demonstrated operational stability over 50 continuous operation. system recovered stable trend minimal decline. Water 1.76 LMH recorded along reverse 292 . observed decline slightly by only 5.6%, which attributed inorganic scaling on surface where cleaning citric acid efficacy in restoring initial flux. • technical viability technology scale appraised. HF evaluated. role unit examined. OC successfully Stable during fouling.
