Dyes employed in many production cycles are characterized by high toxicity and persistence the environment, conventional wastewater treatments often fail to reach removal efficiencies. Consequently, there is an increasing research demand aimed at development of more efficient sustainable technologies. A two-step strategy consisting dye sorption followed sorbent bio-regeneration proposed here, with a special focus on regeneration step. The objective this study was establish best operating conditions achieve dye-loaded polymers concurrently ultimate dyes. To aim, Hytrel 8206 polymer, used as material remove Remazol Red from textile wastewater, investigated two-phase partitioning bioreactor (TPPB) under alternated anaerobic–aerobic conditions. Comprehensive analysis operational parameters, including load initial contamination levels, conducted optimize efficiency. Experimental data demonstrated efficiencies (91–98%) biodegradation up 89%. This also examines process investigate fate intermediates; results confirmed successful degradation without significant by-product accumulation. underscores potential TPPB-based polymeric for treatment, offering promising solution global challenge pollution water resources.
